Irregular exploitation of water resources of the country, especially in the agricultural sector, has threatened Iran with serious threats. The main objective of this study is to provide of possible management strategies at farm level, without changing irrigation systems and additional costs in order to reduce agricultural water consumption such as improving irrigation water efficiency, changing the planting date and studying different levels of deficit irrigation with regarding the type of cultivation, the actual conditions of irrigation management (amount, number of irrigation, etc.) in different areas of the study area have been checked. The basics of the study are based on actual information and in the form of a case study. . The results showed that improvement of irrigation efficiency for dominant crops in two regions of Dorodzan and Korbal, leading to savings in water allocation of 131.5 (11.2%) and 33.8 (10.83%) million cubic meters, respectively. The results of the scenario of change in planting date using AquaCrop model simulation showed that with this management pattern could be saved, 31.6 (2.7%) and 9.17 (2.94%) million cubic meters in the two regions of Dorodzan and Korbal in water consumption respectively . At the same time, different levels of deficit irrigation can save 85.5(7.3%) and 26.2 (8.4%) million cubic meters in water consumption respectively.
