Determining Profitability and the Economic Productivity of Agricultural Water in Crop Production

Today, due to limited resources, increasing the productivity of inputs, especially water inputs in the agricultural sector to achieve food security in the country is a fundamental strategy. In this regard, the objectives of the present study were to determine the physical and economic irrigation water productivity in the production of crop production under research conditions in Seed and Plant Improvement Institute (SPII) research farm in Alborz province based on 2016-2019 dates in 2020. In this study, in order to estimate irrigation water productivity used physical and economic productivity. According to the results, during 2016-2019 years, The mean of sale return percent of irrigated wheat, barley, canola and forage were estimated 13.4, 39.3, 38.9 and 19.5 percent and means of investment return percent of irrigated wheat, barley, canola and forage were estimated 15.5, 64.6, 63.6 and 24.8 percent. The means of physical productivity of irrigation water for wheat, barley, canola and forage were estimated 0.56, 0.51, 0.33 and 2.8 kg/m3 and means of economic productivity of irrigation water based on gross income for wheat, barley, canola and forage were estimated 8996.8, 10431.8, 18750 and 5915.9 rials/m3 and means of economic productivity of irrigation water based on profit for wheat, barley, canola and forage were estimated 1191.1, 10750, 7291.7 and 1312.2 rials/m3.
