The required data for this study has been obtained by using simple random sampling method and questionnaire completion from 207 farmers of this three category. The results of determining the optimal cultivation pattern in three categories indicated that the optimal cultivation pattern according to existing constraints in group of using river water is Onion cultivation before and after targeting the subsidies. In group of using deep wells water, optimal cultivation pattern before targeting the subsidies is cultivation of sorghum, irrigated alfalfa, sunflower and seed watermelon and after targeting the subsidies is cultivation of sorghum, irrigated alfalfa, cumin and seed watermelon. Optimal cultivation pattern before targeting the subsidies for rainfed cultivation is cultivation of Chickpea and Lentil.
