Water availability is a major constraint for production of grain in Australia and improving water use efficiency is a primary target for growers, breeders and agronomists. This publication reflects the Grains Research and Development Corporation’s commitment to improving water use efficiency through projects under the GRDC Water Use Efficiency Initiative, which bring together growers, farming systems groups and researchers across Australia.
The aim of this publication is to provide decision makers with tools to
understand and improve water use efficiency in rainfed systems where
water deficit is a perennial problem. Yield limitations sometimes
imposed by excess water are not considered in this publication.
