values of dry biomass of corn, sugarcane, sorghum, rice, taro, millet, cotton, cowpeas, soybeans, and velvet beans as related to the evapotranspiration (et) were studied. the linear regression model was sufficiently accurate to establish the crop dry biomass and et relations. a water-use efficiency index (wue), which is defined as the additional crop dry biomass per unit et, is used in this study application of the established model to the everglades agricultural area, florida, showed that the regional et can be predicted from the known regional crop yields. the crop yield and et relations could be used as a potential tool to improve water resources planning and management practices for crop production.
