abstract
improving water productivity in food production has been a basic global issue, especially incountries with limited water resources like iran. due to quantitative and qualitative limitationsof water, measurement and analysis of agricultural water productivity indicators in irandeserve special attention. accordingly, in the present study, the physical and economicalproductivity of crops in bahar plain, hamadan, was investigated for the period of 2010-11. inthis research, completing previous studies, water productivity indicators in different irrigationmethods were calculated. the results showed that water productivity of the modern irrigationmethods was significantly higher than traditional irrigation methods. also, based on netbenefit per drop (nbpd) index, garlic and alfalfa, respectively, showed the highest and lowestproductivity. this can be considered as a proposed policy change in cropping pattern.
