Abstract
Crop pattern has significant effect on optimum use of water resources and agricultural management. Present research accomplished to achieve optimum crop pattern in Aharchai Basin located in the downstream of Sattarkhan Dam. The study area is about 3000 ha using traditional irrigation method, wherein low irrigation efficiency and water shortage are the most important problems. In order to determine optimum crop pattern and to provide a suitable way to increase agricultural benefit and productivity, a linear programming model in both cases of the current and improved irrigation system conditions was simulated in the Mathematica software. After simulation, in order to maximize benefits, the area of each product was determined through two different simulation states. Results showed that if agricultural lands employ modern irrigation methods, the benefit of agricultural activities would increase by 30%, i.e. it would rise from 98 to 128 billion Riyals in a year.
