Determination of Energy Input-Output Analysis in Plum (Prunus domestica L.) Production

Abstract

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).
