Abstract:

This study was carried out to understand the effects of conventional irrigation (CI), regulated deficit irrigation (RDI₇₀ and RDI₅₀) and partial root zone drying (PRD₇₀ and PRD₅₀) treatments on water productivity and water use efficiency of sunflower in the Ahwaz Plain, Iran. Irrigation water productivity for seed yield (WP(Ir)Y) and water use efficiency for seed yield (WUE(Y)) were not significantly affected by conventional and limited irrigation treatments. In this study, the highest (WP(Ir) Y) was obtained by limited irrigation treatments (RDI₅₀, PRD₅₀ and RDI₇₀ treatments, with mean 11.62, 11.37 and 11.12 kg mm^-1, respectively.), whereas the lowest (WP(Ir)Y) was obtained from the CI treatment (10.74 kg mm^-1). The maximum WUE(Y) was related to RDI₅₀, PRD₅₀ and RDI₇₀ treatments, averaged 13.88, 13.59 and 13.29 kg mm^-1, respectively. The minimum one was also associated with CI treatment. averaged 12.48 kg mm^-1. It is concluded that the CI treatment is the best choice for maximum yield under the local conditions, but this irrigation scheme must be re-considered in areas where water resources are more limited.
