Abstract

In this study the efficiency of wheat crop in Mahyar plain was investigated using DATA ENVELOPE ANALYSIS (DEA) method. The necessary data were collected from 100 wheat farms. The results indicated that, consumed water with 79.5% and labor force with 0.24% have the most and the least share of energy consumption respectively. Energy productivity, net added energy and output to input energy ratio in this crop were estimated 0.048, 79.34 and 1.63 respectively. The results of DATA ENVELOPE ANALYSIS showed that in constant return to scale model 23% and in variable return to scale model 36% of producers have efficiency of 100% and the other producers have different degrees of inefficiency. Mean of technical efficiency, net technical efficiency and scale efficiency were estimated 90.26%, 95.14% and 94.43% respectively. Also the average of technical efficiency of inefficient units was calculated about 87% based on constant return to scale model. Therefore 13% of inputs can be saved by increasing the efficiency of these units.
