Evaluating Effective Factors on Water Use Efficiency Resources in Wheat

Considering water use efficiency resources and improving productivity level due to the contentious drought is very necessary. It is also notified that considering the effects of these factors and their relations to water inputs and reciprocal influences during consuming production inputs is very important. In this research water use efficiency is studied economically. Moreover, in the first step DEA (Data Envelopment Analysis) is applied toevaluate the technical efficient and use of water resources. In the second step, using Logit Model the led factors to efficient use of water will be recognized. To do so, the information of103 wheat cultivator is analysed in Shahindej, West-Azerbaijan in 2013-2014 during farming season. The results show that the average of water consuming in this region is low, about 56/3%. Variables like literacy level, the importance of water economizing, the soil and irrigationsystem types are positive. On the other hand, variables such as the age and area of field have negative effects on the efficient of irrigation water based on the consonant efficient to the scale. According to these findings, it seems that implementing classes in improving the functions of studied units and costing irrigation policy are very effective
