Abstract

In this study, multi objective programming is used to find deficit strategies with different water use efficiencies. Model activity was divided with water use efficiency at 34%, 40% and 65% with deficit strategies. Model fined optimal crop pattern, suitable irrigation strategies and irrigation methods at usual and drought available irrigation water. Water price of each cubic meter resulting of reduction of water consumption determined for representation farmer. When water consumption objective was more important than gross crops modern irrigation with deficit strategies exist in crop pattern. The percentage decrease on benefit was less than that of the withdrawal for all representative farmers so based on the result farmer can water consumption in optimal level.
