Abstract:
Three cotton (Gossypium hirsutum L.) cultivars were grown under field conditions at Eloy, AZ in 1985 and 1986 to investigate the effects of five drip irrigation treatments on yield, petiole nitrate concentrations, and fruiting characteristics. Irrigation treatments ranged from 59 to 86 cm applied during the growing season. Petiole samples were collected once a week and analyzed for nitrate content. Flower and boll numbers and yield data were recorded throughout both years. Results indicated that irrigation treatments had significant effects on yield with lower amounts of irrigation producing significantly lower lint yields. Significantly lower nitrate concentrations were also observed among the lower irrigation treatments. Irrigation treatments affected flower and boll production with lower irrigation treatments producing fewer flowers and bolls. Irrigation treatments did not significantly influence percent boll set, however, percent boll set was lower in the higher irrigation treatments. The higher irrigation treatments also produced heavier bolls.
