Abstract: Deficit irrigation (DI) has been widely investigated as a valuable and sustainable production strategy in
dry regions. By limiting water applications to drought-sensitive growth stages, this practice aims to
maximize water productivity and to stabilize – rather than maximize – yields. We review selected
research from around the world and we summarize the advantages and disadvantages of deficit
irrigation. Research results confirm that DI is successful in increasing water productivity for various
crops without causing severe yield reductions. Nevertheless, a certain minimum amount of seasonal
moisture must be guaranteed. DI requires precise knowledge of crop response to drought stress, as
drought tolerance varies considerably by genotype and phenological stage. In developing and optimizing
DI strategies, field research should therefore be combined with crop water productivity modeling.
