CROP YIELD FUNCTIONS AND ALTERNATIVE EXPOSURE STATISTICS}, volume={34}, DOI={10.1080/00022470.1984.10465815}, abstractNote={A principal objective of the National Crop Loss Assessment Network (NCLAN) is to develop O/sub 3/ dose-crop yield response models for use in assessing the effects of O/sub 3/ on economically important crop species and cultivars. This paper is part of a third assessment report from NCLAN. The NCLAN is composed of several cooperating programs with field sites in different regions of the country. Open-top chambers allow control of O/sub 3/ concentration-crop yield functions for the major crops studied in 1980 and 1981, and for all crops studied during 1982. Four O/sub 3/ averaging times (exposure statistics) are used in a Weilbull model for each experimental data set. Models derived using two seasonal mean O/sub 3/ statistics (1-h/day and 7-h/day means) and two seasonal peak O/sub 3/ statistics (1-h and 7-h) are compared. The results suggest that all four O/sub 3/ statistics are of similar value when obtained from and used for the same data set. Seasonal mean O/sub 3/ statistics can be used to develop models which can be used to estimate yield of a given crop from data obtained from different sites or from different years at one site. However, peak statistics obtained from one site cannot bemore » used to predict yield from data obtained at a second site, or from data obtained at the same site in different years. 12 references, 4 tables.« less}, number={8}, journal={JOURNAL OF THE AIR POLLUTION CONTROL ASSOCIATION}, author={HECK, WW and CURE, WW and RAWLINGS, JO and ZARAGOZA, LJ and HEAGLE, AS and HEGGESTAD, HE and KOHUT, RJ and KRESS, LW and TEMPLE, PJ}, year={1984}, pages={810–817} }

 @inbook{heck_1973, title={Air pollution and the future of agricultural production}, DOI={10.1021/ba-1973-0122.ch010}, abstractNote={Ozone and sulfur dioxide are presently the most pervasive air pollutants affecting agricultural production. They have a major impact on the growth and productivity of certain sensitive cultivated and native species of plants. These pollutants are a national problem around urban centers but are important in rural areas, particularly throughout the eastern US. The present information base is too diffuse to permit an accurate prediction as to the eventual impact on agricultural production. Management practices would permit us to live with present pollution levels, but a decrease in these levels would be beneficial to agricultural production. Doubling of present levels in the eastern part of the country could result in major yield reduction of important agronomic crops. Long term chronic studies of field problems are essential before an accurate assessment of the impact of air pollutants on agricultural production can be developed.}, booktitle={Air pollution damage to vegetation}, publisher={Washington: American Chemical Society}, author={Heck, W.
