Energiebilanz und Wirtschaftlichkeitsberechnung für die Produktion von Nektarinen (Prunus persica var. nucipersica), eine Fallstudie aus der Provinz Niğde

Abstract

This study was aimed to determine the energy use efficiency and economic analysis of nectarine production for the 2015–2016 production seasons in Nigde province in Turkey. A survey data were collected in 2017 and the farms were selected according to the full counting method and the survey was applied to these farms. In order to determine the energy use efficiency and economic analysis in the production of nectarine, a survey was made with 8 farms that can be reached over 20 decares of nectarine production in Nigde province. According to results of study, human labour energy, machinery energy, chemical fertilizers energy, chemicals energy, organic fertilizers energy, diesel fuel energy, irrigation water energy and electricity energy were calculated as energy inputs. Nectarine fruit was calculated as output. In nectarine production, total input energy was calculated as 29,893.35 MJ ha−1 and total energy output was calculated as 55,731.09 MJ ha−1. The energy inputs in nectarine production were calculated respectively as chemical fertilizers energy 12,900.69 MJ ha−1 (43.15%), electricity energy 6698.27 MJ ha−1 (22.41%), irrigation water energy 4142.05 MJ ha−1 (13.86%), human labour energy 1826.29 MJ ha−1 (6.11%), chemicals energy 1660.69 MJ ha−1 (5.56%), diesel fuel energy 1479.26 MJ ha−1 (4.95%), machinery energy 1134.65 MJ ha−1 (3.80%) and organic fertilizers energy 51.45 MJ ha−1 (0.17%). The energy use efficiency, specific energy, energy productivity and net energy calculations were calculated in nectarine production respectively as 1.86, 1.02 MJ kg−1, 0.98 kg MJ−1 and 25,837.74 MJ ha−1. Benefit-cost ratio was calculated as 2.02 for nectarine production.
