Water scarcity as a limiting factor, vegetation growth and development for arid and semi-arid regions is considered as an inherent limitation for these climates. Due to heavy droughts in the last two decades in Lorestan province as well as excessive water consumption in the agricultural sector caused The issue of water efficiency in the agricultural sector in this province is important and needs many studies. Water resources in the world are limited And due to population growth And the demand for food and water for agricultural production will increase. On the other hand due to the virtual water trade Which is intended as a new solution Dealing with water scarcity is important, producing products that are produced with high water demand, It does not make sense in areas facing a water crisis. One of the ways to increase water use efficiency in agriculture is to increase the physical productivity of crops. For this, a study in the 2016-2017 crop year in the cities of Khorramabad, Durachegni and Kuhdasht have been studied to study the physical productivity of water and the volume of water used in canola cultivation. The results of this study showed that the average rate of physical water productivity in the management conditions of the operators covered by the project, For canola, it is equal to a minimum of 0.5 and a maximum of 0.67 kg / m 3 and an average of 0.613 kg / m 3 . The average volume of water consumed during growing season in the cities of Khorramabad, Durachegni And Kuhdasht are equal to 3588, 2971 and 3428 cubic meters per hectare, respectively.
