Water-Use Efficiency in Crop Production

Abstract

Plant biomass accumulation, and consequently yield, was shown to be inextricably linked to transpiration. The ratio of plant productivity to water loss, water-use efficiency, was very conservative. Only a few variables are available for manipulating water-use efficiency, and these have already been exploited to a large degree.
