Energy efficiency for wheat production using data envelopment analysis (DEA) technique.

This study was carried out to assess wheat production efficiency with regard to energy consumption in two regions of Fars province, Iran. For this purpose, the data were collected from 277 wheat growing farmers of which 135 from region 1 and 142 from region 2, using stratified random sampling method. Efficiency evaluation has done using data envelopment analysis (DEA) technique. The results indicated that total input energy for wheat production were 38589.677 and 38817.823 MJ/ha with the averaged weight yield of 6813.996 and 6046.968 kg/ha in region 1 and 2, respectively. Energy output-input ratio, energy productivity and specific energy were 2.596, 0.178 kg/MJ and 5.603 MJ/kg for region 1, and 2.290, 0.162 kg/MJ and 6.186 MJ/kg for region 2, respectively. The efficiency evaluation disclosed that the number of efficient farmers was more in region 2(16.2%) and for combined seeder (25.53%). Also, it expose that a large number of farmers could improve their efficiency in different ranges of efficiency.
