Abstract :

Limited water resources in Iran and excessive use in irrigated farms, especially in rice cultivation has revealed necessary to increase valuable water factor productivity in rice cultivation. This study has been conducted to calculate and analysis of non-parametric indices of water partial factor productivity in rice cultivation in Mazandaran province, Iran. Thus, data were gathered from production cost of 690 rice farmers in the Jihad-e-Agriculture database of Mazandaran province in 2010 if that were selected by simple random sampling. The results of this study shows, with the increased acreage in the province, increase productivity of water consumption. Also, high-yielding varieties of rice seeds than other rice varieties its highest value is assigned in nonparametric partial productivity indices. These indicators can be compared to experts, managers and decision makers to identify existing problems and ways to help improve water productivity.
