Abstract
Since water is one of the most important factors affecting the production and performance of agricultural products, the efficient management of this scarce resource is considered one of the important fields of agricultural development. The purpose of this research is to analyze and compare the cultivation pattern and the gross profit of farmers in two cases due to the implementation of price and non-price water policies and the implementation of pressure irrigation system in the fields of Erzuye city, one of Kerman province. Irrigation water price policy (increase in water extraction cost) was considered under scenarios of 25, 50, 75 and 100 percent. To achieve these goals, the positive mathematical programming model was used. In order to achieve practical results, production function with constant elasticity of substitution and non-linear cost function were added to this model. The required data were collected using simple random sampling method and completing 100 questionnaires in the crop year of 1401-1400. The obtained results showed that with the adoption of the water price policy, the cultivated area of the crops with the least water consumption increased and other selected products faced a decrease in the cultivated area. Under the last scenario, the gross profit of the model decreased by 26% and at the same time the water consumption decreased by 10.5%. Comparing showed that the implementation of this irrigation system compared to the observed level, increases the net profit of the model by 30.75% and reduces the water consumption of selected crops by 210%
