Abstract
SUMMARY: The biological and economic performance of a cotton crop are examined. The effects of variety, water, sowing date and spacing on crop performance are considered in relation to their effects on crop growth, which had been studied previously, or noted in the literature. Suitable varieties and agronomic practices are discussed. An empirical relationship between available water, dry matter production and yield of seed cotton is evaluated physically and biologically on the basis of Penman's and de Wit's work, and practically in the light of commercial yields and rates of watering.
