Water scarcity will face the world with a crisis of water resources management in the future. Water consumption in the agricultural, as the largest demand for water, has main roll in decision of many stakeholders in the economic, social and political fields. Nevertheless, research on its efficiency and effectiveness were done. On the other hand, due to droughts in the last two decades in Lorestan province of Iran and also the excessive consumption of water in agriculture, the issue of water efficiency in the agricultural is important and needs several studies. For this reason, a study was conducted to investigate the physical productivity of water and the volume of water used in sugar beet cultivation in the 2018-19 years in the city of Kuhdasht. The results of this study showed that the average rate of physical water productivity in the management conditions of the beneficiaries covered by the project, for sugar beet crop is equal to 6.06 kg per cubic meter and the volume of water consumed during the growing season is equal to 14841 cubic meters. At the end of the project and according to the obtained results, detailed recommendations were provided to the users in order to improve productivity and reduce the volume of water consumed.
