With limited water resources and the effects of climate change in recent decades As well as increasing the needs of the industrial, drinking and environmental sectors, water consumption in the agricultural sector as the main consumer of water resources should be controlled in favor of other sectors. In this regard, determining and analyzing water productivity indicators can be a good solution for correct policies for the production of agricultural and non-agricultural products in the pursuit of maximum profit, sustainable development, food security, productive employment and the like. It was enough to determine the correct water consumption. The CPD index can be used as an indicator to evaluate the annual changes in agricultural water productivity in the country. This study was conducted to determine water productivity by calculating the CPD index in farms under dominant cultivation in the region, including cereals, vegetables, weeds and forage crops in Andimeshk region of Khuzestan in three cropping years of 89-88, 90-89 and 91-90. The results showed that the average water productivity in onion is 1.01, tomato 0.94, watermelon 0.88, cucumber 0.84 and wheat 0.76 (kg/m3) among which onion is the most correct consumption in terms of utilization. Water and wheat had the highest water consumption in the study area
