The relative importance of various physiological responses in determining the effect of water supply on the yield of cotton is unknown, though the effects themselves are well recognized. Excess water leads to rank growth which aggravates disease and pest problems. Water stress adversely affects the production of flower buds and boll setting, and can reduce yield by reducing boll size. Both have a significant effect on the time taken for a crop to reach maturity.
