In the current situation, analyzing the physical and economic efficiency of water in crops with the approach of reducing the risk of irrigation management is very important and has a special place. The aim of this research was to analyze water efficiency with two traditional and new (classical) irrigation methods in major agricultural crops of Hamedan city. The statistical population of the research was equal to 350 farmers who cultivated selected crops (garlic, wheat, barley, alfalfa, potatoes), of which 55 people were selected and interviewed according to the Cochran formula for the sample size. Sampling was done in a stratified random manner. The data was collected through interviews and the completion of a researcher-made questionnaire, the validity of which was confirmed by a group of specialists and experts in agricultural economics, irrigation and agriculture of the Agricultural Jihad Organization and the Agricultural and Natural Resources Research Center of Hamedan Province, and its reliability was confirmed by Cronbach's alpha coefficient. Data analysis and in other words, water productivity in selected crops in farms has been calculated using non-parametric method and three indices CPD, BPD and NBPD. The results showed that potato, garlic, barley, alfalfa and wheat products had the highest physical productivity respectively. Potato has the highest productivity with 3.96 and 2.87 kg per cubic meter of water in modern and traditional irrigation systems, respectively. On the other hand, wheat has the lowest physical productivity with productivity of 0.62 and 1.18 in traditional and modern irrigation methods, respectively. According to the economic productivity index, garlic, potato, wheat, barley and alfalfa products had the highest productivity. In the garlic product, 8083 and 9028 million rials of profit have been obtained for each cubic meter of water in the traditional and modern methods, respectively. On the other hand, alfalfa with productivity of 31 and 42 thousand rials has had the lowest economic productivity in traditional and modern irrigation methods, respectively. According to the results, it is suggested that products such as garlic, which has the highest productivity, should be used in the development of cultivation in the region and replaced by products with lower economic productivity.
