In recent years, the area of adaptation for bermudagrass has progressively expanded to cooler climates due to the development of more cold‐tolerant cultivars. The expanded area of adaptation as well as the reduced inputs required to maintain healthy turfgrass have made bermudagrass a popular choice in areas of marginal adaptation. In these areas, the greatest threat to bermudagrass health and survivability is winterkill. This management guide seeks to describe winterkill: what it looks like, what causes it, and where it occurs. Additionally, this management guide describes best management practices to both prevent winterkill and recover bermudagrass from winterkill damage.}, journal={Crop, Forage & Turfgrass Management}, author={Hutchens, W.

Intact grass-soil cores were collected from six cultivars grown in a field trial under no-irrigation for 3 years. Tall fescue under irrigation was also sampled from an adjacent area as the contrast. Bacterial and fungal communities in roots, rhizosphere, and bulk soil were examined for abundance, diversity, and composition using quantitative-PCR and high-throughput amplicon sequencing of 16S rRNA gene and ITS regions, respectively. Differences in microbial community composition and structure between non-irrigated and irrigated samples were statistically significant in all three microhabitats. No-irrigation enriched Actinobacteria in all three microhabitats, but mainly enriched Basidiomycota in the root endosphere and only Glomeromycota in bulk soil. Tall fescue cultivars slightly yet significantly modified endophytic microbial communities. Cultivars showing better adaptability to drought encompassed more relatively abundant Actinobacteria, Basidiomycota, or Glomeromycota in roots and the rhizosphere. PICRUSt2-based predictions revealed that the relative abundance of functional genes in roots related to phytohormones, antioxidant enzymes, and nutrient acquisition was enhanced under no-irrigation. Significant associations between Streptomyces and putative drought-ameliorating genes underscore possible mechanics for microbes to confer tall fescue with water stress tolerance.

Crop coefficients (Kc) have traditionally been utilized to assist in reducing irrigation by comparing reference evapotranspiration (ETo) to actual evapotranspiration (ETa) of specific crops. However, Kc values are most relevant during times of nonlimiting conditions and do not quantify the amount turfgrasses restrict evapotranspiration (ET) under moderate drought stress. Stress coefficients (Ks) estimate water needs while maintaining minimally acceptable turfgrass quality. The objective of this study was to derive Ks values for four bermudagrass (Cynodon spp.) cultivars managed in the transition zone. Direct measurements of actual evapotranspiration were made through weighing lysimetry during a 2‐year field study. Experimental units were allowed to naturally dry down near wilting point and maintained at a steady level of soil moisture to calculate Ks for each cultivar. A lower Ks value indicates increased turfgrass tolerance to water stress; whereas a Ks value ≥1 suggests higher soil moisture levels are required to sustain turfgrass quality. ‘TifTuf’, ‘Latitude 36’ and ‘Tifway’ were the best performing cultivars with mean Ks values of 0.747, 0.766, and 0.796, respectively. ‘Celebration’ had the highest Ks value of 0.944.

The identification of new sources of genetic resistance to shade will expand the germplasm pool available to breeders for developing improved bermudagrass cultivars. In this study, 24 common bermudagrass accessions recently introduced from South Africa were evaluated for their ability to persist under shade. Entries were established in a randomized complete block design with three replications at the Lake Wheeler Turfgrass Field Lab (Raleigh, NC) in the spring of 2019. Following full green‐up in summer 2020, entries were evaluated for performance under full sun, and then a 63% shade cloth was installed over the plots. Traits evaluated under shade included: turfgrass quality, turfgrass density, genetic color, ground coverage, turfgrass regrowth and the normalized difference vegetation index (NDVI). A turfgrass performance index (TPI) was calculated to identify the top performers across all traits. Under full sun, seven accessions had comparable performance with ‘Celebration’ and ‘TifTuf’ across traits. Under shade, ‘Stil03’, ‘Q 47620’, ‘TifGrand’, ‘WIN10F’, Celebration, and TifTuf exhibited the highest TPI.

This review compared twenty-five peer-reviewed studies that evaluated changes in soil bulk density, infiltration rate, hydraulic conductivity, and water retention where compost was incorporated into urban soils. A wide range of compost rates and incorporation depths were evaluated in these studies across many soil types. Compost incorporation generally reduced bulk density, enhanced infiltration and hydraulic conductivity, and increased water content and plant available water, compared to unamended controls. In the four studies on runoff water quality, compost incorporation often resulted in higher initial nutrient content in runoff water, but also enhanced grass growth and reduced sediment loss. Few studies evaluated multiple compost application rates or incorporation depths, and the ways in which compost application rates were reported varied widely between studies making it difficult to directly compare them. Four studies investigated the long-term effects of compost incorporation, and there was no clear pattern of why some soils display enhanced physical properties over time and others do not.

Reduced clippings on the surface can increase surface uniformity, a primary goal for lawn mower use. This study was conducted to determine the effectiveness of mulching mower units to reduce clipping particle size compared with traditional side-discharge mower units. Three commercially available mowers of different horsepower/ size were tested in mulching and side-discharge modes of operation to evaluate clipping parameters from tall fescue and zoysiagrass maintained under typical home-lawn conditions. Turfgrass species and mower size had a greater impact on clipping length and specific projected area than mode of operation. Tall fescue clippings were 28% longer than zoysiagrass and had a 34% greater specific projected area. A medium or large mower produced clippings 28 to 31% shorter than the small mower and decreased the specific projected area by 19 to 32%. Mulching operation did not decrease clipping size as hypothesized. Instead, mulching resulted in average increases of 9 and 0.2% in clipping length and specific projected area, respectively. A side discharge mode of operation may result in fewer clippings on the surface, increasing surface uniformity compared to a mulching mode of operation. I t has been reported that recycling lawn clippings promotes retention of plant nutrients and enhances turfgrass quality (Heckman et al., 2000; Kopp and Guillard, 2002; Bigelow et al., 2005). Little information has been found in the literature as it relates to turfgrass particle size from mowing and decomposition rates. Studies by Angers and Recous (1997) reported the decomposition of rye (Secale cereal L.) green residues and wheat (Triticum aestivum L.) straw was influenced by particle size. It seems reasonable to postulate from previous work that smaller turfgrass clippings are more likely to filter down through the turfgrass canopy to the soil surface, enhancing the onset of decomposition and providing an environmental benefit. From a consumer’s perspective, fewer clippings visible on the turfgrass surface can result in a more uniform, attractive turfgrass canopy.

The response of measured colorant color parameters to pre-application irrigation was variable among products tested. Turf colorants with increased product viscosity benefit from pre-application irrigation. Turf colorants are primarily used on warm-season grasses throughout the southern United States to maintain aesthetic quality leading into and during winter dormancy. To maximize aesthetic quality, turf colorants must be applied when certain conditions are present. The objective of this field study was to evaluate the presence of leaf moisture during turf colorant application to dormant turfgrass and its effect on measured color parameters (color, intensity, and hue angle). Four turf colorants were applied to wet and dry (i.e., irrigated and non-irrigated) dormant ‘Tifsport’ hybrid bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt-Davy] and ‘El Toro’ zoysiagrass (Zoysia japonica Steud.). Color parameters were evaluated weekly for 5 consecutive weeks following turf colorant application. Average colorant color and intensity ratings were 14 and 10% higher when dormant turfgrass was irrigated prior to colorant application, respectively. Color and intensity ratings were unaffected by leaf wetness following applications of Endurant Premium and Green Turf Paint applications. However, color and intensity ratings increased by 38 and 26%, respectively, when turfgrass was irrigated prior to the application of Green Lawnger and Ultradwarf Super. Negative effects (i.e., streaking) commonly seen during application of turf colorants higher in viscosity were alleviated as a result of pre-application irrigation. Hue angles quantified from digital images were unaffected by the presence of leaf wetness during colorant application. Results from this research indicate turfgrass managers should consider wetting dormant turfgrass through a quick irrigation cycle to mitigate possible unattractive streaking that result from the use of higher-viscosity products or increased application rates.}, number={1}, journal={CROP FORAGE & TURFGRASS MANAGEMENT}, author={Pinnix, Garland D. and McCauley, Raymond K. and Miller, Grady L.}, year={2019}, month={Mar} } @article{shaddox_fu_gardner_goss_guertal_kreuser_miller_stewart_tang_unruh_et al._2019, title={Solubility of Ten Iron Fertilizers in Eleven North American Soils}, volume={111}, ISSN={["1435-0645"]}, DOI={10.2134/agronj2018.12.0770}, abstractNote={Core Ideas Non‐chelated Fe sources resulted in little to no increase in soluble Fe at 1 h and 21 d.

Numerous products are marketed as Fe chelates but few have been confirmed to increase Fe solubility in soils. The objective of this study was to determine the solubility of Fe from 10 common Fe fertilizers applied to 11 North American soils. Brookston, Cecil, Fuquay, Hallandale, Marietta, Marvyn, Nunn, Pinavetes, Stephenville, Troup, and Zook soils were incubated with soluble Fe applied as sulfate; glucoheptonate; polysaccharide; humate; oxide; citrate; 1,2 dicarboxyethyl D,L aspartic acid (IDHA); ethylenediaminetetraacetic acid (EDTA); diethylenetriaminepentaacetic acid (DTPA); and ethylenediamine‐o‐hydroxyphenylacetic acid (EDDHA). At 1 h, 1 d, 1 wk, 2 wk, and 3 wk, soils were extracted with 0.01 mol L–1 CaCl2 and analyzed for Fe. In each soil 1 h after application, greater than 95% of applied Fe was rendered insoluble from sulfate, glucoheptonate, polysaccharide, humate, and oxide. The chelates FeEDTA, FeDTPA, and FeEDDHA resulted in increased Fe solubility compared with untreated soil within each sampling time in most soils with Fe solubility at 21 d ranging from 5 to 40% of applied Fe. The natural organic chelate (NOC), FeIDHA, increased Fe solubility in 3 of the 11 soils for 1 d, but soluble Fe from FeIDHA declined to that of untreated soils thereafter.

In most tropical and warm, temperate regions, bermudagrass (Cynodon spp.) is the foundation of the turfgrass industry (Taliaferro et al., 2004). Development of bermudagrass for turfgrass began in the early 1900s. Much of this development has involved the hybridization of Cynodon dactylon (L.), a tetraploid recognized as an invasive weed species in many regions, andC. transvaalensis (Burt-Davy), a more erect-growing diploid (de Wet and Harlan, 1970; Harlan and de Wet, 1969). Early turfgrass-breeding programs have aimed to develop better bermudagrasses to replace sand putting greens or seeded varieties (i.e., Burton, 1991). Today, the goal of many breeding programs is to create cultivars that are adapted to a broader range of environments and have improved drought tolerance. The latter is particularly important, as irrigation restrictions during drought events are becoming more common. Improved drought tolerance allows turfgrass to maintain growth and metabolic activities under water deficits through physiological processes, including osmotic adjustment, maintenance of root viability, and membrane stability (Huang et al., 2014; Nilsen and Orcutt, 1996). DT-1, an interspecific triploid (2n = 3x = 27) hybrid of C. transvaalensis and C. dactylon, was tested in 19 drought-stress trials in Georgia, Florida, North Carolina, Oklahoma, and Texas before it was co-released from the University of Georgia and the U.S. Department of Agriculture–Agricultural Research Service in 2014 and commercially named ‘TifTuf’ (Hanna and Schwartz, 2016). Potential uses of DT-1 include sports turfgrass, home lawns, and golf course roughs, fairways, and tee boxes. DT-1 better withstands drought and traffic than previous commercial releases. In addition, it is generally faster growing than other bermudagrass cultivars and maintains turfgrass cover and green color longer into the fall. The objective of this manuscript is to summarize the performance, quality, and drought tolerance research leading to the release of DT-1.}, number={11}, journal={HORTSCIENCE}, publisher={American Society for Horticultural Science}, author={Schwartz, Brian M. and Hanna, Wayne W. and Baxter, Lisa L. and Raymer, Paul L. and Waltz, F.

Turf colorant applications that occur in colder temperatures increases the risk of colorant transfer onto absorbent materials. Turf colorant selection is imperative as certain products are able to adhere to the turfgrass canopy better than others. Turf colorants are used to provide green color to turfgrasses during times of stress and dormancy. When used to treat dormant turfgrass, proper application timing is imperative to increase functionality. The objective of this field study was to evaluate effects of air temperature on colorant transfer onto an absorbent material. Seven turfgrass colorants were applied to dormant ‘Tifway’ hybrid bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt‐Davy] and ‘El Toro’ zoysiagrass (Zoysia japonica Steud.) at three air temperatures (25, 45, and 60°F). Colorant transfer for each air temperature treatment was sampled at 1, 2, 4, and 7 days after application (DAA) by dragging an absorbent cloth the length of treated turfgrass plots. When applied at 25°F, colorant transfer was 2.2 and 2.3 times greater than the amount transferred at 45 and 60°F, respectively. Regreen, Fairway, Perennial Ryegrass, and Premium all exceeded the threshold for colorant transfer (0.030 reflectance) 7 DAA when applied at 25°F. Spaint was the only product to have an acceptable measure of colorant transfer across air temperatures. Additionally, Regreen did not have an acceptable level of colorant transfer at any point during evaluations. When applied at 45 and 60°F, colorant transfer for Spaint, Green Turf Paint, and Green Dye Turf were at least 5 and 6 times lower, respectively, compared to other colorants.

Turfgrass colorants are primarily used as an alternative to winter overseeding. Information on colorants is limited in the scientific literature. The primary objective of this field study was to evaluate the effect turfgrass colorants had on color parameters (colorant intensity, color, and hue angle) of dormant bermudagrass (Cynodon sp.). Secondary objectives were to examine colorant transfer (wipe off) from the turfgrass surface to an absorbent material and to measure product viscosities. Twenty‐five colorants were applied at two spray volumes (75 and 112 mL m–2) on dormant bermudagrass at two heights of cut (0.3 and 1.5 cm). Multidimensional scaling and cluster analysis were used to separate colorants based on measured color parameters. Group 1 colorants maintained colorant intensity the longest, but colorant color was reduced at application due to the appearance of bright blue (e.g., Munsell 5BG/6/6) and bright green (e.g., Munsell 7.5GY/7/10) colors. Group 2 colorants provided the darkest green (e.g., Munsell 5GY/4/4) color, while Group 3 colorants provided minimal color change of dormant turfgrass. Among the Group 2 colorants, Green Lawnger, Lesco Green, Ultradwarf Super, Southwest Green, and Endurant provided a natural green color. Measurements of colorant transfer showed that Blue, Regreen, SprayMax, Green Dye Turf, Titan Green Turf, Solarogen, and Endurant have the highest propensity to disassociate from treated turfgrass.

As new zoysiagrass (Zoysia spp.) cultivars are released, field studies on N responses and mowing heights conducted over several years under different environments are needed to determine best management practices. This study was initiated to (i) characterize a general response (color, density, turf quality) to N fertilization rate, mowing height, and their interactions among zoysiagrass cultivars; and (ii) establish appropriate mowing height and N rate recommendations for each of the cultivars studied. Four Japanese lawngrass cultivars (Z. japonica Steud.) and four manilagrass cultivars (Z. matrella L. Merr.) were evaluated in Citra, FL, for 4 yr and in Raleigh, NC, for 2 yr under three N rates (73, 171, and 268 kg ha−1 yr−1) and two mowing heights (2.5 and 5.0 cm for Japanese lawngrass; 0.6 and 1.2 cm for manilagrass).

It is essential to understand underlying factors controlling water loss to more precisely predict irrigation requirements and develop new strategies for improving effective use of water. In this study, we investigate two key components of potential water loss from a bentgrass (Agrostis stolonifera L.) system that have not previously been examined in detail: 1) water loss in darkness, and 2) water loss through evaporation directly from the soil. The experiments were conducted in controlled environment chambers with intact cores from the field. An automated gravimetric system and soil moisture probes allowed precise measurements of water loss over ranges of vapor pressure deficits (VPD). The gravimetric and soil probe results indicated that substantial evapotranspiration occurred in darkness, at rates 40 to 60% of that in the light across VPDs. Simulations using field weather data from dry and humid environments indicated nighttime water loss rates would be expected to be 30 to 40% of that in the light. Using cores treated with a fast-acting, desiccating herbicide that eliminated transpiration but kept core resistances intact, evaporation directly from the soil surface was estimated to account for 40% of total water loss in the light and 60 to 70% in the dark. The results, collectively, indicated that water loss in darkness must be separately accounted for to accurately estimate daily evapotranspiration totals and irrigation requirements. Furthermore, because of the very high potential for evaporative water loss in the light and dark, efforts to improve water use efficiencies in the turfgrass system should include strategies that regulate both transpiration by the plant and evaporation from the soil surface.}, journal={AGRICULTURAL AND FOREST METEOROLOGY}, author={Rosas-Anderson, Pablo and Taggart, Matthew J. and Heitman,

Based on the literature, further improvements in shade tolerance can be attained through changes in nitrogen fertility rates, mowing heights, and the application of plant growth regulators. In this study, two South African hybrid (Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy) bermudagrass accessions (‘WIN10F’ and ‘STIL03’) and three standard cultivars (Celebration, Tifgrand, and ‘Tifway’) were compared for their ability to persist under 63% shade, two mowing heights, two trinexapac-ethyl (TE) treatments, and two nitrogen fertility rates. The experimental design was a strip-strip-split plot and digital image analysis was used to measure percent turfgrass cover, percent turfgrass spread after cup-cutter removal, and percent turfgrass re-growth after divot formation. Turf quality was measured using the normalized difference vegetation index (NDVI). Differences among genotypes, TE treatments, and mowing heights were observed across all response variables in 2014 and 2015. Differences in fertility treatments were observed in NDVI, percent turfgrass growth, and percent turfgrass recovery within and across years. Significant differences were observed for the interactions between entry by plant growth regulator (PGR) treatments, entry by mowing height, and mowing height by PGR. These results suggest shade management recommendations should be dependent on genotype and site-specific considerations.

It was further hypothesized they may also alter transpiration and canopy temperature by disrupting gas exchange at the leaf surface. Growth chamber experiments evaluated the effects of air temperature and six colors of paint on daily water loss and canopy temperature in ‘Tifway’ bermudagrass [Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt‐Davy]. Daily water loss and canopy temperature were measured every 24 h using gravimetric techniques and an infrared digital thermometer, while lab experiments examined the thickness of white and black paint on the leaf surface. In nonpainted bermudagrass canopies, daily water loss increased (P ≤ 0.0001) with canopy temperature from 29 to 36°C, while in painted bermudagrass canopies it decreased (P ≤ 0.0001) as canopy temperature increased from 29 to 40°C. Yellow and white paint impacted transpiration and canopy temperature the least, while black and blue caused the greatest reductions in transpiration and highest increases in canopy temperature. Cross‐sections of painted Tifway indicate that paint may limit evaporative cooling by clogging stomata. Increased absorption of radiant energy by paint coupled with limited evaporative cooling result in increased heat stress and decreased turfgrass performance in painted canopies.}, number={4}, journal={Crop Science}, publisher={Crop Science Society of America}, author={Reynolds, William Casey and Miller, Grady L. and Livingston, David P. and Rufty, Thomas W.}, year={2016}, pages={2016} } @misc{miller_2016, title={Athletic field paint impacts transpiration and canopy temperature in bermudagrass}, author={Miller, Grady}, year={2016}, month={Nov} } @book{miller_peacock_bruneau_yelverton_kearns_brandenburg_bowman_cooper_martin_2016, place={Raleigh, NC}, title={Carolina Lawns: A Guide to Maintaining Quality Turf in the Landscape}, number={AG-69}, institution={North Carolina State University Cooperative Extension Service}, author={Miller, G.L. and Peacock, C. and Bruneau, A. and Yelverton, F. and Kearns, J.P. and Brandenburg, R. and Bowman, D.C. and Cooper, R.J. and Martin, M.}, year={2016}, month={May} } @inbook{miller_2016, place={Raleigh, NC}, title={Chapter 9 - Lawns}, url={http://content.ces.ncsu.edu/9-lawns}, booktitle={Extension Gardener Handbook}, publisher={NC State Extension}, author={Miller, G.}, editor={Moore, K.A. and Bradley, L.

A commonly used method relies on commercial software package SigmaScan Pro to quantify mean hue angle, saturation, and brightness values from turf images, and to calculate a dark green color index as the measure of color. To enable turf image analysis to function on an open‐source platform, a method was developed within ImageJ to batch process turf images for color parameters. This Java‐based ImageJ plugin quantifies hue angle, saturation, and brightness values and calculates a dark green color index. In addition, information on the variability of these color parameters can be simultaneously acquired. This new method was used to quantify color parameters of turf images collected from field plots of tall fescue (Schedonorus arundinacea Shreb. Dumort.), Kentucky bluegrass (Poa pratensis L.), ryegrass (Lolium ssp.), hybrid bermudagrass (Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt‐Davy), and creeping bentgrass (Agrostis stolonifera L.). While color parameter values differed little between ImageJ and SigmaScan, the time saved in processing images using ImageJ was considerable. Aside from software, analysis of color parameters acquired from the five turfgrass species indicated that hue angle alone can adequately measure turf color in digital images. Results also demonstrated that, in addition to light source, camera settings should remain fixed during photo capture to avoid introducing errors.

Inorganic soil amendments are used to increase moisture and nutrient retention and may influence N and P leaching. This study was conducted to determine whether N and P leaching could be reduced using soil amendments and surfactant‐modified soil amendments. Treatments included a control (sand), sand–peat, zeolite, calcined clay, hexadecyltrimethylammonium–zeolite, and hexadecyltrimethylammonium–calcined clay. Lysimeters were filled with a 30‐cm rootzone layer of sand–peat (85:15 by volume), below which a 5‐cm treatment layer of amendments was placed. A solution of NO3–N, NH4–N, and orthophosphate‐P (2300, 2480, and 4400 μg mL−1, respectively) was injected at the top of each lysimeter, and leachate was collected using an autocollector set to collect a 10‐mL sample every min until four pore volumes were collected. Uncoated amendments, sand, and peat had no influence on NO3–N retention, whereas hexadecyltrimethylammonium‐coated amendments reduced NO3–N leaching to below detectable limits. Both coated and uncoated amendments reduced NH4–N leaching, with zeolite reducing NH4–N leached to near zero regardless of hexadecyltrimethylammonium coating. Pure sand resulted in a 13% reduction of applied orthophosphate‐P leaching, whereas peat contributed to orthophosphate‐P leaching. Surfactant‐modified amendments reduced orthophosphate‐P leaching by as much as 97%. Surfactant‐modified soil amendments can reduce NO3–N, NH4–N, and orthophosphate‐P leaching and, thus, may be a viable option for removing leached N and P before they enter surface or ground waters.Core Ideas Soil amendments did not reduce NO3–N leaching. Modified soil amendments reduced NO3–N, NH4–N, and orthophosphate‐P leaching.

The objective of this study was to quantify actual evapotranspiration (ETa) and to develop crop coefficients (Kc) for four warm-season turfgrass species, namely ‘Tifway’ bermudagrass (Cynodon dactylon (L.) Pers. x Cynodon transvaalensis Burtt-Davy), ‘Empire’ zoysiagrass (Zoysia japonica Steud.), ‘Floratam’ St. Augustinegrass [Stenotaphrum secundatum (Walter) Kuntze], and ‘Argentine’ bahiagrass (Paspalum notatum Flugge). Crop coefficients were derived by dividing ETa (measured directly from lysimeter weight change over 24 to 72-h periods) by reference evapotranspiration (ETo) calculated from the ASCE–EWRI Standardized Method using onsite weather station data. Data were collected over three seasons from non-stressed, well-watered turf. For 17 of the 30 measurement periods, Kc did not differ among the 4 species, and on 24 of 30 periods zoysiagrass, bermudagrass, and St. Augustinegrass Kc did not differ from one another. A trend toward elevated Kc was observed in bahiagrass in years 2 and 3, particularly during early spring measurement periods. Kc values for all species fluctuated across seasons and years, peaking to ∼0.8 during active growth periods when vapor pressure deficit and solar radiation were greatest, and declining to ∼0.3 in late fall and winter. Root growth differences among the species appeared to have a stronger relationship to ET rates than did shoot growth rate. Results demonstrated that the commonly recommended warm-season turf coefficient of 0.6, while approximating overall average annual ETa, under-predicted ETa during active growth periods and over-predicted ETa during late fall and winter periods, when turf was slowly growing or quiescent. The results indicate seasonal refinement of Kc values may be needed to more effectively meet consumptive water use requirements of warm-season turfgrasses.}, journal={AGRICULTURAL WATER MANAGEMENT}, author={Wherley, B. and Dukes, M.

A total of 47 experimental hybrid bluegrass lines and three commercial checks, ‘Rebel Exeda’ tall fescue (Festuca arundinacea Schreb.) and ‘Reveille’ and ‘Thermal Blue Blaze’ hybrid bluegrass (P. arachnifera × P. pratensis) were evaluated at five locations (Auburn, AL, Starkville, MS, Raleigh, NC, Knoxville, TN, and Dallas, TX) from 2009 to 2012. DALBG 1201 was characterized by its superior turfgrass quality, darker green color, and higher shoot density than Reveille and Thermal Blue Blaze. Its leaf texture was finer than Rebel Exeda and similar to the hybrid bluegrass checks. Linear regression analysis for turfgrass quality indicated that DALBG 1201 was more stress tolerant compared with the three commercial checks and was highly stable across varying environmental conditions.

Research was initiated to determine the effect of calcium silicate on silicon uptake, turf quality, and its residual activity in providing plant available Si in two turfgrass systems. During 2005 and 2006, calcium silicate (CaSi, 12% Si) was applied as a topdressing at eight rates ranging from 0 to 342 kg m−2 to a ‘Tifdwarf’ (Cynodon dactylon × C. transvaalensis Burtt Davy) green in the spring and to the same plots overseeded with ‘Wintergreen’ rough bluegrass (Poa trivialis L.) in the fall. At initiation of the study, dolomitic limestone and magnesium sulfate (MgSO4) was applied to equilibrate calcium across all treatments based on the highest rate of CaSi. Every 28 days, treatments were rated for turf quality and then harvested to determine Si accumulation. One month after applying CaSi in 2005, Si concentration in the leaf tissue of Tifdwarf had increased linearly with increasing rates. This response continued through the months of May, June, July, August, and October with a 9%, 21%, 40%, 22% and 21% increase in Si concentration in the leaf tissue between the control and the 342 kg m−2 rate, respectively. Although the rate response remained, there was an overall drop in average percent Si accumulation in leaf tissue across the treatments beginning three months after the first application. Similar responses were noted with the overseeded rough bluegrass with a 46%, 85%, 69%, 111% and 58% increase in Si concentration in the leaf tissue between the control and the 342 kg m−2 rate, respectively. In contrast to the bermudagrass, over the five month period following application, the residual activity of Si in rough bluegrass remained high, suggesting that rough bluegrass might be a better Si accumulator in comparison to Tifdwarf bermudagrass. The second run of the experiment (2006–2007) and the residual trial had the same response with Si concentration in the leaf tissue increasing as the amount of CaSi applied increased.

Visible light and photosynthesis share the same wavelengths (400–700 nm), and it was hypothesized that alterations in visible light to produce specific colors would lead to reductions in photosynthetically active radiation (PAR) and total canopy photosynthesis (TCP). Lab experiments using a spectroradiometer and LICOR 1800‐12 integrating sphere examined the impacts of 10 colors of athletic field paint on PAR as well as wavelengths within PAR. These colors were then applied weekly for 5 wk to ‘Tifway’ bermudagrass [Cynodon dactylon (L.) Pers. × Cynodon transvaalensis Burtt Davy], and TCP was measured using a gas exchange system 24 h after each application. Spectroradiometry analyses revealed the significant effects of paint color (P ≤ 0.001) on reflection, transmission, and absorption of PAR. Lighter colors including white, yellow, orange, and red reflected 47 to 92% of PAR while darker colors including green, black, and dark blue absorbed 87 to 95% of PAR. Accompanying gas exchange measurements revealed that TCP was most negatively correlated with absorption of PAR (r = −0.959, P ≤ 0.001) and that darker colors negatively impact TCP more than lighter colors. The results clearly indicate that damage to turfgrasses with long‐term painting will be difficult to avoid, and this is particularly true with darker colors of paint.}, number={5}, journal={CROP SCIENCE}, author={Reynolds, William Casey and Miller, Grady L. and Rufty, Thomas W.}, year={2013}, pages={2209–2217} } @misc{miller_2013, title={Beyond Fertility Programs}, author={Miller, Grady}, year={2013}, month={Nov} } @inproceedings{cooper_shea_peacock_miller_john_2013, title={Influence of Spray Volume, Post-Application Irrigation and Canopy Height on the Persistence and Distribution of Prodiamine Residues Following Application to a Tall Fescue Lawn}, volume={12}, booktitle={Proceedings of the International Turfgrass Society Research Journal}, author={Cooper, R.J. and Shea, D. and Peacock, C.H. and Miller, G.L. and John, C.V.}, year={2013}, pages={47–52} } @book{miller_2013, place={Raleigh, NC}, title={It is time for fall seeding of tall fescue}, journal={Turffiles (Turfgrass Information for North Carolina)}, institution={North Carolina State University}, author={Miller, G.L.}, year={2013}, month={Aug} } @article{miller_2013, title={I’ve seen this movie before}, volume={29}, number={7}, journal={SportsTurf}, author={Miller, G.L.}, year={2013}, pages={46} } @inproceedings{miller_2013, title={Keeping your golf course green with turf colorants}, booktitle={Proceedings 2013 Southeastern North Carolina Professional Turfgrass Conference}, author={Miller, G.L.}, year={2013}, month={Mar}, pages={8–11} } @article{miller_2013, title={Making better decisions}, volume={29}, number={3}, journal={SportsTurf}, author={Miller, G.L.}, year={2013}, pages={46} } @article{miller_2013, title={Never stop learning}, volume={29}, number={5}, journal={SportsTurf}, author={Miller, G.L.}, year={2013}, pages={46} } @article{zhang_miller_rufty_bowman_2013, title={Nitrate Leaching from Two Kentucky Bluegrass Cultivars as Affected by Nitrate Uptake Capacity and Subsurface Soil Compaction}, volume={53}, ISSN={["1435-0653"]}, DOI={10.2135/cropsci2012.10.0600}, abstractNote={ABSTRACTThere are a number of strategies to minimize NO3– leaching from turfgrass, including planting turfgrass cultivars with higher NO3– absorption abilities. This column lysimeter study was conducted to examine NO3– leaching from two Kentucky bluegrass (Poa pratensis L.) cultivars differing in NO3– uptake capacity. Subsurface soil compaction was included as a second factor. Tillers of Julia and Midnight Kentucky bluegrass, previously identified as having high and low NO3– uptake capacity, respectively, were grown in column lysimeters. Each column was filled with Wagram loamy sand with or without a subsurface compaction layer 8.5 cm below the surface. The two cultivars were established and then treated to impose moderate N deficiency. Potassium nitrate was applied in solution at 49 kg N ha–1 followed by daily heavy irrigation. Leachate was collected and analyzed for NO3–‐N. Cumulative N leaching loss of applied N ranged from 2.6 to 19% and 2.8 to 21% for Julia and Midnight, respectively. In two out of three trials, both cultivars absorbed NO3– very efficiently in noncompacted soil, with only trace amounts of NO3– leaching. While NO3–‐N loss averaged 4.7% of applied N in noncompacted soil across all trials, subsurface soil compaction increased that to 8.9%. Results indicated that despite being identified as more efficient for NO3– uptake, NO3– leaching from Julia was generally similar to that from Midnight. Soil conditions and differences in root morphology and/or architecture may played a more important role than root uptake capacity in determining NO3– leaching from these Kentucky bluegrass genotypes.}, number={4}, journal={CROP SCIENCE}, author={Zhang, Chenxi and Miller, Grady L. and Rufty, Thomas W. and Bowman, Daniel C.}, year={2013}, pages={1722–1733} } @article{zhang_rufty_miller_bowman_2013, title={Nitrate Uptake Rates of Kentucky Bluegrass Genotypes and Their Effect on Nitrate Absorption under Competitive Conditions}, volume={53}, ISSN={["1435-0653"]}, DOI={10.2135/cropsci2012.10.0597}, abstractNote={ABSTRACTNitrate leaching from turfgrasses continues to be a concern. It is proposed that selecting turfgrass genotypes with higher NO3− absorption abilities could reduce NO3− leaching. This study examined the intraspecific difference in NO3− absorption among Kentucky bluegrass (Poa pratensis L.) genotypes and how such a difference affects N absorption when roots are in competition for soil N. A nutrient solution screening procedure was used to identify Kentucky bluegrass genotypes having high vs. low NO3− uptake capacity. Tillers of 60 Kentucky bluegrass cultivars were rooted and transferred to a continuous flow solution culture system. After establishment, plants were treated to develop moderate N deficiency. Isotopically labeled (15N) KNO3 was introduced at high (1 mM) and low (0.05 mM) concentrations to screen for differences in NO3− uptake. After a brief uptake period, plants were harvested, dried, and analyzed for 15N content to determine N uptake rate. There were significant differences among genotypes for uptake rate at both high and low N concentrations. The 60 genotypes exhibited a wide range of uptake rates, with strong correlation between rates at high and low N. The cultivars Julia and Midnight were selected as representing cultivars with efficient and inefficient NO3− uptake, respectively. Julia had NO3− uptake rates averaging 56% higher than Midnight. A subsequent lysimeter study examined whether higher NO3− uptake capacity would translate into increased N absorption under competitive conditions. Tillers of the two cultivars were planted as a mixed stand in soil or sand column lysimeters. After establishment, 15N‐labeled KNO3 solution at high (2 or 1mM) and low (0.05mM) concentrations was applied to each column. After an uptake period, individual plants of each cultivar were harvested for 15N analysis. Results indicated that Julia absorbed 20 to 50% more NO3− than Midnight at the high N concentration and 25 to 71% more NO3− more than Midnight at the low N concentration. Most differences were statistically significant. This indicates that differences in NO3− absorption by Kentucky bluegrass identified in solution culture translate into differences in absorption of soil N.}, number={3}, journal={CROP SCIENCE}, author={Zhang, Chenxi and Rufty, Thomas W. and Miller, Grady L. and Bowman, Daniel C.}, year={2013}, month={May}, pages={1179–1188} } @article{miller_2013, title={Overseeding options}, volume={29}, number={11}, journal={SportsTurf}, author={Miller, G.L.}, year={2013}, pages={46} } @book{brandenburg_butler_gannon_martin_miller_peacock_richardson_warren_yelverton_2013, place={Raleigh, NC}, title={Pest Control for Professional Turfgrass Managers}, number={AG-408}, institution={North Carolina State University}, author={Brandenburg, R. and Butler, L. and Gannon, T. and Martin, M. and Miller, G. and Peacock, C. and Richardson, R. and Warren, L. and Yelverton, F.}, year={2013} } @inproceedings{cooper_miller_peacock_hinton_2013, title={Spring establishment rate varies among zoysiagrass species and cultivars}, volume={12}, booktitle={Proceedings of the International Turfgrass Society Research Journal}, author={Cooper, R.J. and Miller, G.L. and Peacock, C.H. and Hinton, J.}, year={2013}, pages={201–206} } @article{miller_2013, title={Team play}, volume={29}, number={9}, journal={SportsTurf}, author={Miller, G.L.}, year={2013}, pages={46} } @article{miller_pinnix_2013, title={Turfgrass colorant evaluation}, volume={81}, number={10}, journal={Golf Course Manage}, author={Miller, G.L. and Pinnix, D.}, year={2013}, pages={96} } @article{grabow_ghali_huffman_miller_bowman_vasanth_2013, title={Water Application Efficiency and Adequacy of ET-Based and Soil Moisture-Based Irrigation Controllers for Turfgrass Irrigation}, volume={139}, ISSN={["1943-4774"]}, DOI={10.1061/(asce)ir.1943-4774.0000528}, abstractNote={Abstract Increasing competition for water and the desire for high-quality turfgrass require sound irrigation water management.

However, field managers notice chronic declines in turfgrass health after repeated applications. This study examines athletic field paint impacts on spectral quality and associated turfgrass photosynthesis. Growth chamber experiments evaluated effects of red and white athletic field paint as well as one, two, three, and four repeated weekly applications on total canopy photosynthesis (TCP) of perennial ryegrass (Lolium perenne L.). Paint treatments were applied weekly for 6 wk with TCP recorded 24 h after each application using a gas exchange system. Spectroradiometry experiments evaluated reflection, absorption, and transmission of light at various wavelengths based on paint color, dilution, and thickness. Over a six week period all treatments reduced TCP based on color (P ≤ 0.0001) and dilution (P ≤ 0.0001). Red no‐dilution paint produced a 75% reduction in TCP over 6 wk while white 1:1 diluted paint only produced a 19% reduction. Spectroradiometry data suggests this is likely due to reductions in photosynthetically active radiation (PAR) with red paint absorbing 51% of incident PAR while transmitting and reflecting 6 and 43%, respectively. White paint transmitted 5% of PAR while reflecting 95%. Alterations in light spectral quality resulting from athletic field paint applications can impact PAR, which may result in reduced turfgrass health.}, number={5}, journal={CROP SCIENCE}, author={Reynolds, William Casey and Miller, Grady L. and Rufty, Thomas W.}, year={2012}, month={Sep}, pages={2375–2384} } @article{briscoe_miller_brinton_bowman_peacock_2012, title={Evaluation of 'Miniverde' bermudagrass and 'Diamond' zoysiagrass putting green establishment using granular Fertilizer Applications}, volume={47}, number={7}, journal={HortScience}, author={Briscoe, K. and Miller, G. and Brinton, S. and Bowman, D. and Peacock, C.}, year={2012}, pages={943–947} } @article{hinton_livingston_miller_peacock_tuong_2012, title={Freeze tolerance of nine zoysiagrass cultivars using natural cold acclimation and freeze chambers}, volume={47}, number={1}, journal={HortScience}, author={Hinton, J.

Previous research developed an index known as the dark green color index (DGCI) via DIA as an indicator of turf color. The objective of this study was to use DGCI variability to better predict a visual rating (VR) index used to evaluate tall fescue (Festuca arundinacea Schreb.) color under different irrigation treatments. To develop DGCI statistics, two freeware software packages (Image J and R) were used to extract and process information from digital images. The model to predict VR from DIA was developed and calibrated using candidate DGCI statistical moments from 120 images in a calibration data set using a multiple linear regression procedure. Fitness of calibration and validation models were verified using the adjusted coefficient of determination, root mean square error, and the Mallow's Cp statistic. The two‐variable model produced more precise estimates (adjusted R2 = 0.926 and 0.899) than the model that only used one term in predicting the VR values (adjusted R2 = 0.879 and 0.843) for calibration and validation sets, respectively. These data suggest incorporating a measure of color uniformity improves the use of DGCI in predicting VR values compared to using only the mean of DGCI values to predict VR values. Model refinements may be needed for other turf species, but current work suggests using additional statistical moments such as SD improves VR estimate precision and accuracy.}, number={5}, journal={CROP SCIENCE}, author={Ghali, Ihab E. and Miller, Grady L. and Grabow, Garry L. and Huffman, Rodney L.}, year={2012}, month={Sep}, pages={2365–2374} } @article{miller_2012, title={What makes a field good?}, volume={28}, number={9}, journal={SportsTurf}, author={Miller, G.L.}, year={2012}, pages={46} } @inproceedings{miller_2011, title={Athletic Field Management}, author={Miller, Grady}, year={2011}, month={Dec} } @inproceedings{miller_2011, title={Baseball Fall Fertilization for Overseed and Non-Overseed}, author={Miller, Grady}, year={2011}, month={Sep} } @misc{miller_2011, title={Bentgrass Decline: Influence of Cultural Practices}, author={Miller, Grady}, year={2011}, month={Dec} } @misc{miller_2011, title={Establishment of Turfgrasses}, author={Miller, Grady}, year={2011}, month={Feb} } @inproceedings{miller_2011, title={Evaluation of Athletic Field Paints and Turf Colorants and their Impact on Turfgrass Performance}, author={Miller, Grady}, year={2011}, month={Jun} } @article{miller_2011, title={First timer}, volume={27}, number={11}, journal={SportsTurf}, author={Miller, G.L.}, year={2011}, pages={50} } @misc{miller_2011, title={Granular Fertilizer Programming}, author={Miller, Grady}, year={2011}, month={Nov} } @article{miller_2011, title={Head games}, volume={27}, number={7}, journal={SportsTurf}, author={Miller, G.L.}, year={2011}, pages={54} } @article{miller_2011, title={High-performance grasses in NC State’s cultivar-evaluation program}, journal={North Carolina Turfgrass}, author={Miller, G.L.}, year={2011}, month={May}, pages={12,14–17} } @misc{miller_2011, title={Irrigation Design Principles}, author={Miller, Grady}, year={2011}, month={Jul} } @inproceedings{miller_2011, title={Irrigation Management and Smart Controllers for P&R Use}, author={Miller, Grady}, year={2011}, month={Sep} } @misc{miller_2011, title={Irrigation Management and Smart Irrigation Controllers}, author={Miller, Grady}, year={2011}, month={Dec} } @misc{miller_2011, title={Landscape Fertility Programs}, author={Miller, Grady}, year={2011}, month={Mar} } @misc{miller_2011, title={Landscape Turf Selection and Management}, author={Miller, Grady}, year={2011}, month={Jan} } @inproceedings{miller_2011, title={Managing Lawns during the Worst of Times}, author={Miller, Grady}, year={2011}, month={May} } @misc{miller_2011, title={Managing Ultradwarf Bermudagrass Golf Greens in NC}, author={Miller, Grady}, year={2011}, month={Apr} } @article{miller_2011, title={Maximizing the durability of athletic fields}, journal={North Carolina Turfgrass}, author={Miller, G.L.}, year={2011}, month={Sep}, pages={8–13} } @article{miller_2011, title={Maximizing the durability of athletic fields}, volume={27}, number={1}, journal={SportsTurf}, author={Miller, G.L.}, year={2011}, pages={22–25} } @misc{miller_2011, title={NCSU Research at Lake Wheeler Field Lab}, author={Miller, Grady}, year={2011}, month={Oct} } @misc{miller_2011, title={NTEP Cultivar Evaluations}, author={Miller, Grady}, year={2011}, month={Aug} } @misc{miller_2011, title={New Discoveries with Athletic Turf Paints}, author={Miller, Grady}, year={2011}, month={Jun} } @article{carley_goodman_sermons_bowman_miller_rufty_2011, title={Organic matter accumulation in creeping bentgrass greens}, volume={79}, number={4}, journal={Golf Course Manage}, author={Carley, D.S. and Goodman, D. and Sermons, D.S. and Bowman, D. and Miller, G. and Rufty, T.}, year={2011}, pages={99} } @inproceedings{miller_2011, title={Products Necessary for Safe, Attractive, and Playable Athletic Surfaces}, author={Miller, Grady}, year={2011}, month={Nov} } @inproceedings{vick, jr._grabow_huffman_miller_2011, title={Residential Irrigation and Water Conservation Potential of Smart Irrigation Technologies in the Catawba River Basin}, ISBN={9780784411735}, url={http://dx.doi.org/10.1061/41173(414)282}, DOI={10.1061/41173(414)282}, abstractNote={A three year residential lake water use study in the Catawba River Basin was initiated in 2009 to assess current water withdrawals for landscape irrigation and the water conservation potential of "smart irrigation" technologies. The study is being conducted by North Carolina State University, on properties bordering Duke Energy managed lakes, in North Carolina and South Carolina, that withdraw lake water for landscape irrigation. Assessment of current irrigation water use began in 2009 with a survey to which over 1,400 residences responded (reflecting a 7.4% return rate). Survey results were used to select thirty-six residences (twelve on each of three lakes along the Catawba River) for further evaluation. Water meters with loggers were installed on the main lines of irrigation systems of the selected residences in the summer of 2009 to monitor lake water withdrawals for landscape irrigation under current practices. Two weather stations and four atmometers were also installed in the region to monitor reference evapotransporation during the study. Three types of smart irrigation technologies (two ET-based controllers and one soil-moisture sensor system) were installed at twenty-seven of the study sites at the beginning of the 2010 irrigation season. The technologies were distributed such that each lake had six sites with ET-based controllers, three sites with soil-moisture sensors, and three sites with no intervention, which would serve as a comparison group. Metering of irrigation water withdrawals continued throughout the 2010 irrigation season after installation of smart irrigation technologies. Turf quality assessments were made throughout the year using a visual turf quality rating and a Normalized Difference Vegetative Index (NDVI) obtained with a turf color meter.

In this transition zone study, we characterized temporal and spatial aspects of OM accumulation, in an attempt to assess the effectiveness of management and to begin to uncover the processes controlling C sequestration. Root zone samples were collected from sand‐based putting greens at 49 golf courses of various ages, generating 212 individual observations. Organic matter accumulated hyperbolically over time in the top 2.5 cm; apparent critical levels of 40 g kg−1 were exceeded within 5 yr. At a depth of 2.5 to 7.6 cm, accumulation was much slower and linear over time, and critical levels were not reached even after 20 yr. Oxygen levels were never depressed more than 15%, indicating that intensive management of the upper soil profile was successfully allowing gas exchange into the root zone. Carbon accumulated in the soil profile hyperbolically, reflecting changes in the large OM pool near the soil surface. The sequestration rate of 59 g m−2 yr−1 over 25 yr was less than that observed by others examining soil under bentgrass greens in different environments. The evidence indicates that OM and C accumulation are strongly influenced by increasing microbial degradation rates as turfgrass systems age.}, number={3}, journal={Agronomy Journal},

A variety of technologies are available in the market that seeks to reduce irrigation water use. These technologies include rain sensors, and soil moisture sensor (SMS) based and evapotranspiration (ET) based controllers. A study was conducted in Cary, North Carolina with the purpose of evaluating the effectiveness of two smart systems, based on the amount of irrigation applied and turf quality in residential settings. The study included 24 residential sites that were divided into six geographical regions, each group within a region receiving four different treatments. The treatments were: SMS) an irrigation controller with a soil moisture sensor, ET) an evapotranspiration based controller, ED) a standard irrigation controller using seasonal runtimes based on historical climate data and Control) irrigation controller with no intervention. Data was collected from May 2009 through September 2009. Maximum water savings were achieved by the SMS treatment followed by ET, ED and Control treatments. According to visual turfgrass rating, only the Control group was found to have turf quality below an acceptable level.}, number={10095811009581}, publisher={American Society of Agricultural and Biological Engineers}, author={Nautiyal, M. and Grabow, G.L. and Miller, G.L. and Huffman, R.L.}, year={2010} } @article{briscoe_miller_brinton_2010, title={Evaluation of green turf colorants as an alternative to overseeding on putting greens}, journal={Applied Turfgrass Science}, author={Briscoe, K. and Miller, G. and Brinton, S.}, year={2010}, month={Mar}, pages={1–8} } @article{briscoe_miller_brinton_2010, title={Evaluation of green turf colorants on putting greens}, journal={North Carolina Turfgrass}, author={Briscoe, K. and Miller, G. and Brinton, S.}, year={2010}, month={Jul}, pages={20–22} } @book{miller_2010, place={Raleigh, NC}, title={Fall seeding of tall fescue}, journal={Turffiles (Turfgrass information for North Carolina)}, institution={North Carolina State University}, author={Miller, G.L.}, year={2010}, month={Aug} } @article{miller_2010, title={Fire ants}, volume={26}, number={5}, journal={SportsTurf}, author={Miller, G.L.}, year={2010}, pages={46} } @article{miller_desjardin_tredway_2010, title={First Report of Marasmiellus mesosporus Causing Marasmiellus Blight on Seashore Paspalum.}, volume={94}, ISSN={["0191-2917"]}, DOI={10.1094/pdis-06-10-0424}, abstractNote={ Seashore paspalum (Paspalum vaginatum Sw.) is a newly cultivated C4 turfgrass that has exceptional salinity tolerance and is highly suited for use on golf courses in coastal areas. In October 2008 and June 2009, circular patches of blighted seashore paspalum ranging from 30 cm to >3 m in diameter were observed in fairways, tees, and roughs established with ‘Supreme’ seashore paspalum at Roco Ki Golf Club in Macao, Dominican Republic. Affected patches were initially chlorotic followed by reddish brown necrosis of leaves and leaf sheaths. Reddish brown-to-gray lesions were also observed on leaf sheaths during the early stages of necrosis. During periods of wet or humid weather from June through October, basidiocarps were produced on necrotic plant tissue and identified as Marasmiellus mesosporus Singer (2). Three isolates were obtained by plating symptomatic leaf sheaths that were surface sterilized with a 0.5% NaOCl solution on potato dextrose agar amended with 50 ppm each of streptomycin, chloramphenicol, and tetracycline (PDA+++). Sequences of the internal transcribed spacer (ITS) region of rDNA, obtained from these three isolates and three stipes of basidiocarps, were identical to each other and 99% similar to a M. mesosporus sequence deposited in the NCBI database (Accession No. AB517375). To confirm pathogenicity, a M. mesosporus isolate obtained from symptomatic plant tissue was inoculated onto 6-week-old P. vaginatum (‘Seaspray’) planted (0.5 mg seed/cm2) in 10-cm-diameter pots containing a mixture of 80% sand and 20% reed sedge peat. Two weeks prior to inoculation, the isolate was grown on a sterilized mixture of 100 cm3 of rye grain, 4.9 ml of CaCO3, and 100 ml of water. Infested grains were placed 0.5 cm below the soil surface for inoculation. Pots were inoculated with five infested grains or five sterilized, uninfested grains with three replications of each treatment. After inoculation, pots were placed in a growth chamber with a 12-h photoperiod set to 30°C during the day and 26°C at night. Approximately 20% of plants in inoculated pots were necrotic 7 days postinoculation and this increased to 75% by 21 days postinoculation. Diseased plants in inoculated pots exhibited symptoms similar to those observed in the field. Leaves were initially chlorotic with brown lesions on lower leaf sheaths and eventually turned necrotic, reddish brown, and collapsed. Pots receiving uninfested grains were healthy and showed no symptoms on all rating dates. At 21 days postinoculation, basidiocarps were observed emerging from three colonized plants at the base of the oldest leaf sheath near the crown. Three reisolations were made on PDA+++ from stem lesions surface sterilized with a 0.5% NaOCl solution. All reisolations were confirmed as M. mesosporus by culture morphology and ITS sequence data. M. mesosporus was previously reported causing disease on American beachgrass (Ammophila breviligulata Fernald) in North Carolina (1) and recently in Japan (3). The pathogen was initially placed in the genus Marasmius and reported as the cause of the disease Marasmius blight (1). Subsequent morphological observation found that the pathogen belonged in the genus Marasmiellus (2). To our knowledge, this is the first report of M. mesosporus causing Marasmiellus blight on seashore paspalum, a high-amenity turfgrass. References: (1) L. Lucas et al. Plant Dis. Rep. 55:582, 1971.

A previous study showed that soil moisture sensors systems SMSs could lead to irrigation water savings during relatively wet/normal weather conditions. This research, as a follow-up comparison, was conducted under dry weather conditions. The first objective was to statistically evaluate the water savings potential of different commercially available SMSs during the first half of 2006. In the second half, the objectives were to quantify irrigation water use and to evaluate turfgrass quality differences among: 1 a time-based irrigation schedule system with and without a rain sensor; 2 time-based schedules compared to SMS-based systems; and 3 SMS-based systems under different irrigation frequencies. The experimental area was located in Gainesville, Fla. and consisted of common bermudagrass Cynodon dactylon L. Pers. plots. Four commercially available SMSs brands Acclima, Rain Bird, Irrometer, and Water Watcher were used to bypass scheduled irrigation cycles when the soil water content at the 7- to 10-cm depth was above field capacity. Time-based treatments with and without rain sensor feedback were set up as comparisons for irrigation depth applied, and a nonirrigated treatment for turf quality comparison purposes was implemented. Due to the dry weather conditions and/or infrequent rain events during the experi- ment, the nonirrigated plots as well as a broken SMS treatment resulted in turfgrass quality below the minimum acceptable level. The rest of the treatments had at least minimum acceptable turf quality. The treatment with rain sensor resulted in 13 to 24% less water applied than without the rain sensor treatment. Most SMS-based treatments resulted in significant irrigation water savings compared to the treatment without rain sensor, which ranged from 16 to 54% in the first half, and from 28 to 83% in the second half of 2006, for three of four SMS brands tested.}, number={3}, journal={JOURNAL OF IRRIGATION AND DRAINAGE ENGINEERING}, author={Cardenas-Lailhacar, Bernard and Dukes, Michael D. and Miller, Grady L.}, year={2010}, month={Mar}, pages={184–193} } @inproceedings{miller_2010, title={Smart Irrigation}, author={Miller, Grady}, year={2010}, month={Jul} } @misc{miller_2010, title={Sports Turf Program at NCSU}, author={Miller, Grady}, year={2010}, month={Sep} } @misc{miller_2010, title={Sports Turf Research}, author={Miller, Grady}, year={2010}, month={Jun} } @misc{miller_2010, title={Sports Turf Research at NCSU: Changing the Color of Turf}, author={Miller, Grady}, year={2010}, month={Apr} } @misc{miller_2010, title={The Importance of Conducting an Irrigation Audit}, author={Miller, Grady}, year={2010}, month={Nov} } @misc{miller_2010, title={Turf Cover to Prevent Soil Erosion}, author={Miller, Grady}, year={2010}, month={Nov} } @misc{miller_2010, title={Turfgrass Evaluation for Sod Production in NC}, author={Miller, Grady}, year={2010}, month={Apr} } @inproceedings{miller_2010, title={Turfgrass Water Management}, author={Miller, Grady}, year={2010}, month={Oct} } @inproceedings{miller_2010, title={Ultradwarf Bermudagrass Management (workshop)}, author={Miller, Grady}, year={2010}, month={Dec} } @misc{miller_2010, title={Update on Raleigh Turf Unit Expansion and Cultural Practices Research}, author={Miller, Grady}, year={2010}, month={Nov} } @misc{miller_2010, title={Using Smart Irrigation Controllers}, author={Miller, Grady}, year={2010}, month={Mar} } @article{schwartz_kenworthy_crow_ferrell_miller_quesenberry_2010, title={Variable Responses of Zoysiagrass Genotypes to the Sting Nematode}, volume={50}, ISSN={["1435-0653"]}, DOI={10.2135/cropsci2008.11.0672}, abstractNote={Sting nematodes (Belonolaimus longicaudatus) can injure roots of many warm‐season turfgrasses in sandy, well‐drained soils and on artificial, sand‐based putting greens. Resistant or tolerant grasses could reduce the need for chemical control. This research was initiated to assess the host status and relative tolerance of six warm‐season genotypes—four zoysiagrasses (Zoysia Willd.), one St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze], and one bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt‐Davy]—to the sting nematode by two screening methodologies in sequential glasshouse trials in 2007. All entries were hosts with final sting populations 1.7 to 11.0 times greater than initial inoculation levels. Results indicate that evaluating root lengths of unestablished sprigs under sting nematode pressure may improve the identification of genotypes with greater genetic tolerance than in methods using established plants. Total root lengths were not reduced by sting nematodes in UFZ‐10, indicating greater tolerance than found in other entries. Treatments of ‘Empire’, ‘Cavalier’, ‘Emerald’, ‘TifEagle’, and ‘Floratam’ inoculated 45 d after planting exhibited total root length reductions of 24, 29, 29, 32, and 37%, respectively, when compared with uninoculated controls. The observed variability suggests that gains from selecting for sting nematode resistance or tolerance are possible in zoysiagrass.}, number={2}, journal={Crop Science}, author={Schwartz, B.M. and

outdoor water conservation. Three brands of evapotranspiration (ET) controllers were selected based on positive water savings results in arid climates. ET controllers were evaluated on irrigation application compared to a time clock schedule intended to mimic homeowner irrigation schedules. Three ET controllers were tested: Toro Intelli-sense; ETwater Smart Controller 100; Weathermatic SL1600. Other time-based treatments were TIME, based on the historical net irrigation requirement and RTIME that was 60% of TIME. Each treatment was replicated four times for a total of twenty St. Augustinegrass plots which were irrigated through individual irrigation systems. Treatments were compared to each other and to a time-based schedule without rain sensor (TIME WORS) derived from TIME. The study period, August 2006 through November 2007, was dry compared to 30-year historical average rainfall. The ET controllers averaged 43% water savings compared to a time-based treatment without a rain sensor and were about twice as effective and reducing irrigation compared to a rain sensor alone. There were no differences in turfgrass quality across all treatments over the 15-month study. The controllers adjusted their irrigation schedules to the climatic demand effectively, with maximum savings of 60% during the winter 2006–2007 period and minimum savings of 9% during spring 2007 due to persistent dry conditions.

These “Smart Irrigation” technologies include evapotranspiration (ET)-based controllers and soil moisture sensor (SMS) controllers. The purpose of this research was to evaluate the effectiveness of these technologies, along with rain sensors, based on irrigation applied and turfgrass quality measurements on St. Augustinegrass (Stenotaphrum secundatum (Walter) Kuntze). Testing was performed on two types of SMS controllers (LawnLogic LL1004 and Acclima Digital TDT RS500) at three soil moisture threshold settings. Mini-Clik rain sensors (RS) comprised six treatments at two rainfall thresholds (3 mm and 6 mm) and three different irrigation frequencies (1, 2, and 7 d/wk). Two ET controllers were also tested, the Toro Intelli-Sense controller and the Rain Bird ET Manager. A time-based treatment with 2 days of irrigation per week without any type of sensor (WOS) to bypass irrigation was established as a comparison. All irrigation controller programming represented settings that might be used in residential/commercial landscapes. Even though three of the four testing periods were relatively dry, all of the technologies tested managed to reduce water application compared to the WOS treatment, with most treatments also producing acceptable turf quality. Reductions in irrigation applied were as follows: 7–30% for RS-based treatments, 0–74% for SMS-based treatments, and 25–62% for ET-based treatments. The SMS treatments at low threshold settings resulted in high water savings, but reduced turf quality to unacceptable levels. The medium threshold setting (approximately field capacity) SMS-based treatment produced good turfgrass quality while reducing irrigation water use compared to WOS by 11–53%. ET controllers with comparable settings and good turf quality had −20% to 59% savings. Reducing the irrigation schedule (treatment DWRS) by 40% and using a rain sensor produced water savings between 36% and 53% similar to smart controllers. Proper installation and programming of each of the technologies was essential element to balancing water conservation and acceptable turf quality. Water savings with the SMS controllers could have been increased with a reduced time-based irrigation schedule. Efficiency settings of 100% (DWRS) and 95% (TORO) did not reduce turf quality below acceptable limits and resulted in substantial irrigation savings, indicating that efficiency values need not be low in well designed and maintained irrigation systems. For most conditions in Florida, the DWRS schedule (60% of schedule used for SMS treatments) can be used with either rain sensors or soil moisture sensors in bypass control mode as long as the irrigation system has good coverage and is in good repair.}, number={11}, journal={AGRICULTURAL WATER MANAGEMENT}, author={McCready, M.

The effect of irrigation frequency was also a part of the study. Estimates of turf ET were obtained from the Penman-Monteith equation using on-site weather data, and also from an atmometer. Results from the twenty week evaluation in 2007 showed that on average the “add-on” soil-moisture-based system evaluated applied the least amount of water while the ETbased system evaluated applied the most water. Weekly irrigation frequencies used the least amount of water, followed by bi-weekly and daily frequencies in increasing amounts when averaged across all technologies. Minimally acceptable turf quality was maintained by all technologies and frequencies through most of the study, but turf quality declined substantially the last month of the study for the add-on system and standard timer-based system.

This manuscript gives a preliminary report on the evaluation of three commercially available evapotranspiration (ET) based controllers in residential landscaped plots with respect to irrigation application and landscape quality compared to a homeowner irrigation schedule. The irrigation treatments were as follows: T1, Weathermatic Smart Line Series controller; T2, Toro Intelli-sense; T3, ETwater Smart Controller 100; T4, a time-based treatment; and T5, 60% of T4. This paper reports preliminary results from May 25, 2006 to November 30, 2006. T1 overestimated ETo by 32%, but applied less water than all other treatments during the summer season. Water savings occurred even though ETo was overestimated due to an underestimation of the crop coefficient for warm season turfgrass [0.85 in Allen et al. (1998)] programmed into the controller (0.60) and due to frequent irrigation event bypass during the rainy summer season. The Weathermatic controller applied 11% and 14% less water than the theoretical gross irrigation requirement during the summer and fall seasons, respectively. The Toro Intelli-sense controller applied 126 mm in the fall, which was 40% less than theoretical requirements, and had the most accurate ETo of all the controllers. The ETwater controller overestimated ETo by 7% and applied 63% more irrigation water than was required theoretically. During this preliminary testing, the ET controllers did not result in turf quality below acceptable levels.}, booktitle={World Environmental and Water Resources Congress 2007}, publisher={American Society of Civil Engineers}, author={Davis, Stacia and Dukes, Michael D. and Vyapari, Sudeep and Miller, Grady L.}, year={2007}, month={May} } @inproceedings{shedd_dukes_miller_2007, title={Evaluation of Evapotranspiration and Soil Moisture-Based Irrigation Control on Turfgrass}, ISBN={9780784409275}, url={http://dx.doi.org/10.1061/40927(243)238}, DOI={10.1061/40927(243)238}, abstractNote={A variety of commercially available technologies for reducing residential irrigation water use are available to homeowners.

A new generation of synthetic turfgrass is made of plastics with different composite materials, and is supported by a sand and/or rubber infill material and subsurface base layer. Synthetic turfgrass is being increasingly used on many athletic fields, such as soccer, football and rugby, as well as in urban landscapes. It is superior to natural grass in aspects, such as lower maintenance, no irrigation required, and surface uniformity. However, high temperatures on synthetic turfgrass surface during hot weather may be dangerous and could result in heat related health problems, such as heat stroke. The objective of this study was to evaluate the temperature increase among different synthetic turfgrass types and to predict temperature increase on the synthetic turfgrass surfaces. In this study, four types of synthetic turfgrasses (1 – 4) with four infill materials and base layers (A – D) were installed in central Florida, surrounded by large irrigated natural grass fields. Temperature measurements were taken at 23.5 cm above the ground and 5 cm below the ground. The results indicated that there were no differences in air temperatures above the ground between the synthetic turfgrass and the natural turfgrass, due to the small size of the plots and the high wind speed during the daytime. The temperature below the surface (base temperature) for the synthetic turfgrass was always higher than the natural surfaces at noon time. The base temperature differences between the two surfaces were higher in July and August and lower in November. Overall, the infill temperature difference increased with an increase of the depth of the base layer and the color of synthetic turfgrass. Base temperature increase on synthetic turfgrass (Tsyn) was linearly related to the incoming solar radiation (Rs). Relationships based on solar radiation and temperature on natural surfaces (Tnat) (both natural grass and bare soil surface) were developed for all units (Tsyn – Tnat = a Rs + b) so that the temperature increase on synthetic turfgrass could be predicted.}, booktitle={World Environmental and Water Resources Congress 2007}, publisher={American Society of Civil Engineers}, author={Jia,

DOI={10.1094/ats-2005-0531-01-mg}, abstractNote={Double-ring infiltrometers are routinely used by turfgrass specialists, soil scientists, and other professionals to measure the infiltration rate of field sites. Measurement of infiltration rate is important in proper golf course design development and other scenarios that require estimates of runoff. This study compared several commonly performed double-ring infiltration methods as follows: 30- (inner) and 60-cm (outer) diameter rings with a constant water depth (head), 15- (inner) and 30-cm (outer) diameter rings with a constant head, and 15- (inner) and 30-cm (outer) diameter rings with a falling inner head. In addition, a Mariotte siphon device was fabricated to maintain a constant inner head for the 15-cm diameter rings. The 15- and 30-cm rings with the constant head resulted in significantly higher infiltration rates compared to 30- and 60-cm diameter rings with a constant head and 15- and 30-cm rings with a falling head. This was due to variation in the 30- and 60-cm test inner ring water level that had to be maintained manually and because of the non-constant water level in the 15- and 30-cm falling head test. Thus, we concluded that the constant head 15- and 30-cm double-ring test was adequate to represent the infiltration rate in the sandy soils tested. The Mariotte siphon device made it easy for one person to conduct a test while maintaining a constant inner head under infiltration rates ranging from 22 to 225 mm/h.}, number={1}, journal={Journal of Applied Turfgrass Science}, publisher={American Society of Agronomy}, author={Gregory, Justin H. and Dukes, Michael D. and Miller, Grady L. and Jones, Pierce H.}, year={2005} } @article{baum_dukes_miller_2005, title={Analysis of Residential Irrigation Distribution Uniformity}, volume={131}, ISSN={0733-9437 1943-4774}, url={http://dx.doi.org/10.1061/(asce)0733-9437(2005)131:4(336)}, DOI={10.1061/(asce)0733-9437(2005)131:4(336)}, abstractNote={Irrigation has become commonplace for residential homeowners desiring high quality landscapes in Florida. The goal of this project was to document irrigation system uniformity in Central Florida and to quantify distribution uniformity of residential sprinkler equipment under controlled conditions. The catch-can testing procedure used was a modified version of both the American Society of Agricultural Engineers standard and Florida Mobile Irrigation Laboratory ~MIL! procedures. The modified version included a larger sample size to ensure complete sample collection over the entire irrigated area. The standard MIL procedure may overestimate the uniformity for residential systems. From the tests on residential irrigation systems, the average low quarter distribution uniformity sDUlqd value was calculated as 0.45. Rotary sprinklers resulted in significantly higher DUlq compared to fixed pattern spray heads with 0.49 compared to 0.41, respectively. From uniformity tests performed on rotor and spray heads under ideal conditions, rotor heads had more uniform distributions than the spray heads of 0.55 compared to 0.49, respectively. Spray heads had better uniformity when fixed quarter circle nozzles were used as opposed to adjustable nozzles. Both residential irrigation system and controlled tests resulted in sDUlqd at the low end of industry guidelines.

Automation of irrigation systems, based on soil moisture sensors (SMSs), has the potential to provide maximum water use efficiency by maintaining soil moisture at optimum levels. The objectives of this experiment were to quantify differences in irrigation water use and turf quality between: 1) a SMS-based irrigation system compared to a completely time-based scheduling, 2) different commercial irrigation SMSs, and 3) a completely time-based scheduling system with or without a rain sensor. The experimental area consists of common bermudagrass (Cynodon dactylon L.), located in Gainesville, Florida. Four quarter-circle pop-up sprinklers, in a square with 3.66 m sides, irrigated each of 64 plots, distributed in a completely randomized design. Treatments consisted of irrigating one, two, or seven days a week. Each of these schedules compared four different commercial SMSs brands.

Tropical signalgrass is especially problematic for St. Augustinegrass sod producers because of lack of control options. The objectives of our research were to determine the effect of light, pH, temperature, water potential, and planting depth on tropical signalgrass germination and emergence. Tropical signalgrass germination does not require light and is optimum at pH 5 to 6, temperature 25 C, and water potentials greater than − 0.4 MPa. Tropical signalgrass shoots emerged from depths of 0 to 7 cm, with maximum germination when placed on the soil surface. Tropical signalgrass seedlings emerged in the field during the second week of March in Ft. Lonesome, FL. Weekly mean soil and ambient air temperatures at the time of emergence were 20 C. Tropical signalgrass emergence was first observed at 118 and 73 growing degree-days (GDD) (13 C base temperature), with a peak emergence period at 222 and 156 GDD for 2001 and 2002, respectively.

Kuntz.] is the preferred warm‐season turfgrass for Florida's commercial and residential landscapes with an estimated 0.7 million hectare under growth and management. Limited published information is available on St. Augustinegrass response to plant growth retardants (PGRs). A 2‐yr study was implemented to monitor St. Augustinegrass turf quality, lateral stolon growth, percent cover, mowing frequency, cumulative turfgrass clippings, and seedhead suppression following PGR application. Treatments were applied on 23 June 1995 and 22 June 1996 as a single application (SIA) at label use rate (LUR) or as twin split applications (TSA) at half LUR each: the sequential application was only used when mowing interval equaled the untreated. The PGRs and rates were flurprimidol [α‐(1‐methylethyl)‐α‐[4‐(trifluoro‐methoxy)phenyl]‐5‐pyrimidine‐methanol] and paclobutrazol [(+/−)‐(R*,R*)‐β‐[(4‐chloro‐phenyl)methyl]‐α‐(1,1‐dimethylethyl)‐1H‐1,2,4‐triazole‐1‐ethanol] at 1.12 kg ha−1 for SIA and 0.56 kg ha−1 for TSA, trinexapac‐ethyl [4‐(cyclopropyl‐α‐hydroxymethylene)‐3,5‐dioxocyclohexane carboxylic acid ethylester] and mefluidide [N‐[2,4‐dimethyl‐5‐[[trifluoromethyl)sulfonyl]amino]phenyl]acetamide] at 0.28 kg ha−1 for SIA and 0.14 kg ha−1 for TSA, and imazapic [(±)‐2‐[4,5‐dihydrol‐4‐methyl‐4‐(1‐methylethyl)‐5‐oxo‐1H‐imidazol‐2‐yl]‐5‐methyl‐3‐pyridine‐carboxylic acid] at 0.028 kg ha−1 for SIA and 0.014 kg ha−1 for TSA. Responses were observed for a 12‐wk period following initial application, and turf quality was acceptable (>7) for all PGRs. Turf quality for imazapic was generally better than the untreated for Weeks 6 to 10. Greatest control of lateral stolon growth 10 wk after initial application was achieved with TSA of imazapic (68%) and mefluidide (61%). Percent cover 12 wk after initial application was lowest for SIA and TSA imazapic (66 and 53%, respectively). Greatest reduction in mowing frequency was provided by trinexapac‐ethyl (50%), while flurprimidol and mefluidide reduced mowing frequency by 26 and 20%, respectively. The only PGR that reduced cumulative turfgrass clippings (CTC) was trinexapac‐ethyl (63%). Greatest seedhead inhibition during peak production (about 35%) was provided by imazapic and mefluidide. The two most effective PGRs were trinexapac‐ethyl (reduced mowing frequency and CTC) and imazapic (controlled lateral stolon growth and seedhead production), while mefluidide demonstrated some potential.

Offering a survey course as a means for introducing students to agriculture is a concept with popular appeal. As a recruiting effort, and as a method of introducing students to horticulture, the Environmental Horticulture Department at the University of Florida, Gainesville, designed a one-credit course for nonmajors. The course was structured to provide a broad overview of horticulture, emphasizing plant use to enhance interior and exterior environments. The intent was to develop a course somewhat similar to an entry-level course for majors, but with each lecture devoted to a single, self-contained topic. When feasible, hands-on activities were incorporated within the classroom presentation. The course ORH 1030-Plants, Gardens, and You was offered for the first time in Summer 1997. It is now offered every semester. The course has one faculty assigned each semester and various other faculty members, including teaching, research, and extension specialists, participate as guest lecturers. Methods to improve the course are discussed by the faculty presenters and the course coordinator each term. Student response to ORH 1030 has been favorable, ratings are high and enrollment in the course has continued to rise from 30 to our current cap of 100. As a means of ensuring that we are meeting the needs of our students and to aid in targeting potential students, a survey was administered in Spring 2000. Students enrolled in the course were surveyed at the beginning and the end of the semester to gain insight into student demographics, horticulture background and experience, reasons for enrollment in the class, and overall interest in the course.}, journal={HortTechnology}, publisher={American Society for Horticultural Science}, author={Bradley, Jennifer Campbell and McConnell, Dennis and Kane,

on tissue analysis. Previous research has indicated that near infrared reflectance spectroscopy (NIRS) may be useful in tissue nutrient concentration determination since it requires minimum sample preparation and has been a reliable predictor of N concentration. The objective of this study was to evaluate the reliability of NIRS in determining P, K, Ca, and Mg concentrations in bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy]. Tissue samples were collected from Florida golf courses, representing different cultivars grown under various conditions and fertilizer regimes. Tissue samples were analyzed using NIRS and traditional wet chemistry (Mehlich-1 extracts analyzed using inductively coupled argon spectrophotometer) before results were statistically compared. Results from wet chemistry analysis averaged 15% lower than those obtained from NIRS. Although results for certain cultivars and elements were positively correlated (`Tifdwarf' Ca, r2 = 0.72; P < 0.01), precision across all cultivars and nutrients was not sufficient (accounted for only 26% of variability) to indicate that NIRS would be an effective management tool for the elements evaluated in this study.}, number={6}, journal={HortScience}, publisher={American Society for Horticultural Science}, author={Miller, Grady L. and Thomas, Adam}, year={2003}, month={Oct}, pages={1247–1250} } @inproceedings{miller_2003, title={Utilizing service learning in your course}, author={Miller, G.L.}, year={2003}, month={Aug} } @inproceedings{miller_2003, title={Warm Season Basics}, author={Miller, Grady L.}, year={2003}, month={Jan} } @article{miller_2003, title={West Florida crew saves the day at Gainesville field day}, volume={20}, number={5}, journal={Florida Turf Digest}, author={Miller, G.L.}, year={2003}, pages={33} } @article{miller_2003, title={Who is on first?}, volume={19}, number={6}, journal={SportsTurf}, author={Miller, G.L.}, year={2003}, pages={50} } @book{miller_2003, title={Who is on first?}, institution={Green Media}, author={Miller, G.L.}, year={2003}, month={Aug} } @misc{miller_2002, title={Baseball and Softball Field Management}, author={Miller, Grady L.}, year={2002}, month={May} } @article{rodriguez_miller_mccarty_2002, title={Bermudagrass Establishment on High Sand-content Soils Using Various N-P-K Ratios}, volume={37}, ISSN={0018-5345 2327-9834}, url={http://dx.doi.org/10.21273/hortsci.37.1.208}, DOI={10.21273/hortsci.37.1.208}, abstractNote={For drainage, turfgrass is often established on sand-based soils, which are typically nutrient-deficient and require supplemental fertilization. The objective of this study was to determine the optimum N-P-K fertilizer ratio for establishing bermudagrass from sprigs in sand. `FloraDwarf' and `Tifdwarf' bermudagrasses [Cynodon dactylon (L.) Pers. × C. transvaalensis Burt-Davy] were sprigged on a United States Golf Association (USGA) green [85 sand: 15 peat (v/v)] in Aug. 1996 at the Univ. of Florida's Envirogreen in Gainesville, Fla. `TifEagle' bermudagrass was sprigged on a USGA green [85 sand: 15 peat (v/v)] and `Tifway' bermudagrass [C. dactylon (L.) Pers.] was sprigged on native soil at Clemson Univ. in Clemson, S.C. in May 1999. Treatments consisted of fertilizer ratios of 1N-0P-0.8K, 1N-0P-1.7K, 1N-0.4P-0.8K, 1N-0.9P-0.8K, and 1N-1.3P-0.8K applied based on a N rate of 49 kg·ha-1/week for 7 weeks. Growth differences were apparent among cultivars. A 1N-0P-0.8K or 1N-0P-1.7K ratio is insufficient for optimum growth of bermudagrass during establishment, even when planted on a soil high in P. Increased coverage rate with additional P was optimized at a ratio of 1N-0.4P at all four sites. Increased coverage with P was greatest on the sand-based greens, probably due to the very low initial P levels of the soils. On two of the sand-based greens, P in excess of a 1N-0.4P ratio decreased coverage rate.}, number={1}, journal={HortScience}, publisher={American Society for Horticultural Science}, author={Rodriguez,

The first objective of this study was to evaluate the use of near infrared reflectance spectroscopy (NIRS) to schedule N fertilization on two dwarf‐type bermudagrasses [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy]. The second objective was to test the accuracy of NIRS‐predicted mineral tissue concentrations. The third objective was to study the effect of N fertility on thatch development. ‘Tifdwarf’ and ‘FloraDwarf’ bermudagrasses grown on sand–peat (9:1 by volume) were subjected to five treatments using time, NIRS‐predicted N thresholds, and a visual quality rating threshold to schedule applications of (NH4)2SO4 for 20 wk per growing season in 1997 and 1998. There were positive linear relationships between total Kjeldahl nitrogen (TKN) and NIRS‐predicted N in 1997 (r2 = 0.76; slope = 0.96) and 1998 (r2 = 0.92; slope = 1.06). NIRS‐scheduled fertility resulted in similar quality with less fertilizer than time or visual quality‐based fertility. The NIRS mineral concentration predictions for K, Ca, Mg, Fe, Zn, Mn, and Cu were positively correlated with traditional laboratory methods, but there was not sufficient precision in measurements to use NIRS for determination of these nutrients.

The objective of this study was to evaluate the capacity of a hand-held chlorophyll meter (SPAD-502) to provide a relative index of chlorophyll concentrations, N concentrations, and visual quality in St. Augustinegrass [Stenotaphrum secondatum (Walt.) Kuntze]. Two experiments were conducted in a greenhouse in 1998 to evaluate the utility of SPAD readings. Established pots of `Floratam' were subjected to weekly foliar Fe treatments at Fe rates of 0 and 0.17 kg·ha–1 for 4 weeks. Six weekly nitrogen fertilizer treatments were applied in the form of ammonium sulfate at N rates of 0, 5.75, 11.5, 17.25, and 23 kg·ha–1 for 4 weeks. Greenhouse SPAD readings were not affected by Fe treatment, but N treatments resulted in differences in SPAD readings, visual quality, and chlorophyll concentrations. The readings were positively correlated with chlorophyll concentrations (r2 = 0.79), visual ratings (r2 = 0.74), and total Kjeldahl nitrogen (TKN) (r2 = 0.71). Readings taken from field-grown `Floratam', `Floratine', and `Floralawn' St. Augustinegrass were poorly correlated (r2 < 0.63) with chlorophyll concentrations and TKN. Unless future techniques improve dependability of the SPAD meter under field conditions for measuring chlorophyll and N concentration of a stand of turfgrass, the usefulness of such readings for the management of St. Augustinegrass seems limited.}, number={4}, journal={HortScience}, publisher={American Society for Horticultural Science}, author={Rodriguez, Ian R. and Miller, Grady L.},

Two field-grown bermudagrass cultivars, `Tifdwarf' and `Tifway', were used to determine the influence of applied K on plant nutrient content and nutrient retention in two soils. Six rates of K ranging from 0 to 390 kg·ha-1 were applied twice per month each growing season from 1992 to 1994. The cultivars were established on both a sand-peat (9:1 by volume) and loamy sand. Potassium chloride and K2SO4 were compared as sources of K, and were applied simultaneously with N applications. Extractable soil K and leaf tissue K concentrations increased with increasing K rates. There was a critical K fertilization level (74 to 84 kg·ha-1) for each cultivar and medium combination beyond which no increase in tissue concentration was observed. Increasing K fertilization resulted in a decrease in extractable Ca and Mg in both media with corresponding decreases in tissue Ca and Mg concentrations. High K rates appear to increase the potential for Ca and Mg deficiencies in bermudagrass, indicating that rates higher than those that provide sufficient K levels for normal growth should not be

Forage samples of Terral ‘817’ wheat, ‘Jenkins’ triticale, and ‘Morrison’ triticale were harvested at growth stages 5.0, 6.5, and 8.0 and AA concentrations and yield determined. Wheat and triticale forage samples were incubated in Dacron bags for 24 h in the rumen of cows to determine the comparative ruminal degradability of their EAA. Forage production among the three cultivars in 1987‐1988 was similar, but in 1988‐1989, Jenkins produced 15% more forage than Terral 817, which produced 14% more forage than Morrison. Essential amino acid concentrations in Jenkins triticale forage were equal to or greater than Terral 817 wheat or Morrison triticale; however, Morrison grain had a greater concentration of all EAA, except lysine, than did grain of Terral 817 or Jenkins. The EAA in Terral 817 forage averaged 25% higher in potential degradability in the rumen than EAA in Jenkins. Terral 817 and Morrison maintained a higher grain yield response to forage removal in contrast to Jenkins. Differences in forage yield, grain yield, and EAA concentration could not always be separated by species.

A field study with six K rates ranging from 0 to 390 kg ha−1 growing month−1 were applied to ‘Tifdwarf’ and ‘Tifway’ bermudagrass [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt Davy] established on a sand‐peat (9:1 by volume) and a Uchee loamy sand (loamy, siliceous, thermic Arenic Hapludult) during 1992–1994. Potassium chloride or K2SO4 were compared as sources of K and were applied with twice monthly N applications. Elemental soil and plant leaf tissue concentrations were measured periodically during the course of the study. By means of an electrolyte leakage (EL) method, predicted lethal temperatures were identified for rhizome samples removed from the field monthly from October through March of 1992–1993 and 1993–1994. Lethal temperatures estimated by EL were compared with those obtained by means of a recovery growth method. Extractable K in the growth media (12‐204 kg K ha−1) and leaf tissue K concentrations (8.9–17.3 g K kg−1 i DM) increased with increasing K rates. Application of high rates of K had no effect on predicted lethal temperatures or plant regrowtho Lethal temperatures for Tifdwarf ranged from °5.8 to −7.0°C, whereas those of Tifway varied from −6.8 to −8.4°C.

The objectives of this study were to evaluate the effects of forage harvest management on subsequent grain yields of triticale (× Triticosecale Wittmack) and wheat to determine the growth stage for cessation of forage harvest to optimize grain and forage production. The effect of defoliation until Feekes Growth Stage (GS) 5.0, 6.5, or 8.0 on forage production and grain yield components of ‘Terral 817’ wheat, ‘Jenkins’ triticale, and ‘Morrison’ triticale was investigated for two growing seasons at Baton Rouge, LA. Plots harvested up to GS 8.0 produced the greatest forage yield both years. There were no significant differences in mean grain yield of the three cultivars between undipped check plots and plots harvested until GS 5.0 either year. A favorable combination of forage and grain yields in 1987–1988 was achieved if the final forage harvest was made at GS 5.0, but the highest yield combination in 1988–1989 was produced by continuing forage harvest until GS 8.0. Clipping significantly reduced lodging and disease incidence during the 1988– 1989 growing season. Defoliation until GS 8.0 resulted in reductions in number of stems m−2, number of spikelets per head, and weight per seed by 37, 11, and 18%, respectively, resulting in a grain yield reduction of 44% compared with the undefoliated plants. Forage utilization should be terminated by the first node stage to minimize grain yield reductions due to tiller mortality, shortened heads, and poor kernel fill.}, number={5}, journal={Crop Science}, publisher={Crop Science Society of America}, author={Miller, G.
