Rows were 1.5 m apart and in-row spacings were 45, 60, 90, 120, and 150 cm. `Royal Jubilee' yielded more than `Prince Charles' in all environments, and the highest yields were associated with low percent culls and high fruit numbers per hectare. Highest yields of marketable fruits (≥4.5 kg/melon) were obtained using polyethylene mulch and areas per plant between 0.4 and 0.9 m2. Average weight per melon, however, was ≥9 kg only at areas per plant >0.9 to 1.0 m2. Unless there is a market for small fruits (≥4.5–9 kg), optimum area per plant was ≈1.0 m2. Results for one plant per hill at one in-row spacing were similar to those for the alternative planting pattern of two plants per hill at half the in-row spacing, thus supporting the feasibility of using the more economical alternative planting pattern.}, number={7}, journal={HORTSCIENCE}, author={Sanders, DC and Cure, JD and Schultheis, JR}, year={1999}, month={Dec}, pages={1221–1223} }

Hybrid tilapia Oreochromis mossambicus×O. niloticus L. were grown in tanks associated with biofilters (sand beds) in which tomatoes Lycopersicon esculentum were grown. The effect of four biofilter volume (BFV)/fish rearing tank volume ratios (0.67/1, 1.00/1, 1.5011, 2.25/1) on water use efficiency was evaluated.‘Laura’(first experiment) or‘Kewalo’tomatoes were grown 4/m2 in biofilters of four different sizes and surface‐irrigated 8 times daily with water from the associated fish tanks. Daily water consumption increased with BFV/tank ratios and with time. Fish production rates increased with biofilter volume in the first experiment, but were not significantly different in the second experiment. Total tomato fruit yield per plot increased from 13.7 to 31.7 kg (Experiment 1) and from 19.9 to 33.1 kg (Experiment 2) with increasing BFV/tank ratio. For fish plus fruit, total energy production increased from 4,950 to 8,963 kcal/ plot and from 4,804 to 7,424 kcal/plot in Experiments 1 and 2, respectively, and protein production increased from 536 to 794 and from 352 to 483 g/plot in Experiments 1 and 2, respectively, with increasing BFV/ tank ratio. Trends in water use efficiency for production of food energy (kcal/L.) and of protein (g/L) in tomatoes and fish were complex.
