The aim of this research is to compose the energy input-output analysis of plum in Nevsehir province in Turkey. This research was conducted at the plum cultivating facilities during the 2015–2016 production seasons in Nevsehir province of Central Anatolian Region in Turkey. The agricultural input energies and output energies used in plum cultivation were calculated to determine the energy input-output analysis. According to the research findings, the energy inputs in plum cultivation were calculated respectively 3920?MJ ha?1 (44.99%) chemical fertilizers energy, 1618.91?MJ ha?1 (18.58%) diesel fuel energy, 1125.85?MJ ha?1 (12.92%) chemicals energy, 1069.20?MJ ha?1 (12.27%) machinery energy, 723.24?MJ ha?1 (8.30%) human labour energy and 255?MJ ha?1 (2.93%) irrigation water energy. Production output plum yield were calculated as 12,112.50?MJ ha?1. The energy output/input ratio, specific energy, energy usage efficiency and net energy calculations were calculated respectively as 1.39, 1.37?MJ kg?1, 0.73?kg MJ?1 and 3400.30?MJ ha?1. 相似文献
