Abstract :
Due to significance of increasing efficiency in water use in this study, by using the CCR and BCC models, the relative efficiency of decision-making units of Gharehghom Basin, in Khorasan razavi province was determined. Irrigation water use efficiency based on the value judgments of decision-making units was investigated by BCC model with weighted restrictions. Results showed that, the performance of units in CCR and BCC models with non-weighted restriction were significantly lower. Most decision-making units were efficient, based on BCC model with weighted restriction. The target inputs and outputs were determined for inefficient decision-making units. The results of the study indicated that implementing suitable price policy for water, training and extension services could be helpful in improving efficiency of decision- making units under study.
