The Determination of Optimum Cropping Pattern with the Aim of Adaptation to Water Shortage Conditions and Increasing Farmers' Income in Terms of Volume Delivery

One of the steps in the groundwater balancing plan is to install a metering and volumetric flow meter for water users of ground water resources. Volumetric water delivery is one of the main components of the groundwater balancing plan. The importance of installing metering and volumetric flow meter of water is essential for any proper planning of water resources and this requires, while eliminating the existing defects, it should improve its efficiency. Managing water resources and the groundwater balancing plan without stakeholder and water users of well participations will not be possible. The studies show that in implementing the groundwater balancing plan, there is no executive solution and a specific version to empower farmers to meet the new conditions of water control and delivery. In this research, some examples of the optimization of farmers' cultivation pattern and training for farmer's income in terms of volume delivery are presented. In this research, determining the optimum cropping pattern in 9 wells agriculture in Qazvin plain was considered in terms of volume delivery and linear programming was used for optimization. In the studied wells, the average productivity, net benefit and water use in the optimum crop pattern with water allocation has increased by 93% and 67.7% respectively and water use has reduced by 15% compared to the formal crop pattern.
