Abstract
In order to evaluate the energy consumption efficiency in the chickpea production system, a field study was conducted in Ayvangharb, Ilam province, Iran during the 2019-2020 growing season and the required agricultural information in all stages of planting, growing and harvesting was collected by filling out a questionnaire and face-to-face interviews with 240 farmers. The results showed that the highest amount of input energy were diesel fuel, chemical fertilizers, seed and cultivation, chemical fertilizers, fuel and seed in mechanized and traditional cultivation, respectively. Energy ratio, energy efficiency, energy intensity and net energy were determined 2.83, 0.27 Kg/ MJ, 3.6 MJ/ Kg and 12272.46 MJ/ ha in mechanized cultivation and 2.41, 0.23 Kg/ MJ, 4.2 MJ/ Kg and 9608.52 MJ/ ha in traditional cultivation ,respectively. The share of direct, indirect, renewable and non-renewable energy was 47, 53, 20, 80% in mechanized cultivation and 38, 62, 31, 69% of total energy consumption in traditional cultivation, respectively. Questionnaire statistics were analyzed by modeling with DEA solver and it was found that fungicides, phosphate fertilizer and pesticides inputs are the best inputs affecting grain yield and straw yield in mechanized and traditional crops. However, these inputs were less efficient in traditional cultivation than in mechanized cultivation. Also, the analysis of indicators showed that the efficiency of mechanized cultivation is higher than traditional cultivation.
