Assessment technical efficiency of energy consumption in chickpea production under dry farming system in Kangavar county of Iran

The main purpose of this study is to apply non-parametric method of data envelopment analysis (DEA) for optimization of energy inputs for chickpea production under dry farming system in Kangavar county of Kermanshah province, Iran. For these aims, ۲۵ chickpea producers under dry farming system were selected for data collection. Inthis paper, six energy as inputs and chickpea yield as output were considered for DEA method. DEA results revealed that the average of technical, pure technical and scale efficiency were calculated as ۰.۷۶, ۰.۹۶ and ۰.۸۲, respectively. The results showed ۵ (۲۰% of total units) and ۱۸ (۷۲% of total units) chickpea producers were efficient in technical and pure technical efficiency, respectively. The total energy saving was estimated about ۱۹.۵۲%. Also, the highest share of contribution to the total savings energy was calculated as ۸۰.۷۴% for diesel fuel.
