Abstract

This paper studies the energy consumption and finding relationship between energy inputs and yield, per hectare production of melon farms in Khorasan Razavi province, Iran. To this end, the data were collected from 94 farmers which were selected based on random sampling method. Total energy inputs in all stages of melon production was estimated as 1069332.26 MJ ha⁻¹. Fuel (81.79%) was the most contributor to the energy consumption followed by Farmyard manure (13.34%). Energy use efficiency and energy productivity were gained 0.18 and 0.23 kg MJ⁻¹, respectively. 84.95% of the total energy input was non-renewable while 15.05% was renewable. The shares of direct and indirect energy inputs were 83.03% and 16.97%. Econometric estimation results revealed that diesel fuel (0.90) had the highest impact among the inputs in melon production. The contribution of machinery, fertilizers, farmyard manure and water for irrigation was significant at the 1% level.

能源投入——伊朗呼罗珊拉扎维省甜瓜生产产量关系及成本分析

本文研究了伊朗呼罗珊拉扎维省甜瓜农场每公顷产量的能源消耗和能源投入与产量之间的关系。为此，采用随机抽样的方法对94名农户进行数据采集。甜瓜生产各阶段的总能量投入估计为1069332.26 MJ ha−1。燃料(81.79%)是最大的能源消耗来源，其次是农家肥(13.34%)。能量利用效率和能量生产率分别提高0.18和0.23 kg MJ−1。不可再生能源占总能源投入的84.95%，可再生能源占15.05%。直接和间接能源投入比重分别为83.03%和16.97%。计量分析结果表明，柴油(0.90)对甜瓜生产的影响最大。机械、肥料、农家肥和灌溉用水在1%水平上贡献显著。
