Abstract

Considering the limitation of water resources and their value in agriculture, the use of any alternative for efficient consumption and optimal use of existing water is essential. One of these solutions is Deficit Irrigation. The purpose of this study was to evaluate how different percentages of reduction in water consumption in different growing stages as Deficit Irrigation scenarios affect the Optimization of Water Use and dominant Cropping Pattern (Wheat, Barley, Sugar beet, Forage Corn, Maize corn and Alfalfa) in Qazvin plain irrigation network. In order to maximize farm income, the Positive Mathematical Programming (PMP) method was used along with the method of Maximum Entropy (ME) based on the reaction functions of the products yield to water in the space of other constraints. The required information for this research was obtained by using two-stage cluster sampling method through completing 144 questionnaires in farming years of 2015-2016. Results showed that by applying Deficit Irrigation at best condition (Reduction of 5% Deficit Irrigation at the Ripening stage for Wheat, Barley, Corn forage, Maize and sugar beet and 5% Deficit Irrigation at vegetative growth stage for Alfalfa), despite the 5. 2% saving in water consumption, it is possible to increase farm income by 0. 4%. On the other hand, depending on the severity of the crisis and the amount of the water scarcity, different decisions to determine the Deficit Irrigation strategy and the region's cultivation pattern would be made. This mean that if more water conservation is desired, the results of the second and third scenarios are best options for the optimal use of land resources and the minimum water consumption. The result also showed that the total area under cultivation of the selected products has decreased in comparison to the base year and lands have changed to uncultivated and fallow lands which in turn reduces the pressure on land resources and increases the possibility of tillage and soil conservation.
