Abstract

In this study, the pattern and efficiency of energy consumption for wheat production was investigated through data envelopment analysis in Chardavol Township, Ilam Province. The results showed that among the energy inputs, fuel energy, seed and Ness fertilizer with respective percent of 48, 22 and 19 had the highest and work force energy, pesticide and oil with respective percent of 24, 45 and 64 had the lowest share was among inputs energy. The average oftotal Entranceenergy input and output for producingdry farming wheat in the region were 10532.90 MJ/ha-1 and 31568.98 MJ/ha-1 respectively. The meanof energy ratio, energy productivity, energy intensity and net surplus energy were 3.04, %13 kg/MJ-1, 8.21 MJ/kg-1 and 21036.07 MJ/ha-1 respectively. The share of direct and indirect, form the total consuming energy were %49/15 and %51/85 respectively. Farmers’ efficiency was calculated through data envelopment analysis (DEA) in CCR and BCC models using EMS software. Technical efficiency, pure technical efficiency and scale efficiency were %88, %97 and %91 respectively. The amount of input energy optimizedby the return model to the scale variablewas 8397.37 MJ/ha-1. The amount of total savable energy in the current condition of the studied region was %17.97 in the BCC model.
