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 29,893.35MJ ha–1 and total energy output was calculated as 55,731.09MJ
ha–1. The energy inputs in nectarine production were calculated respectively as chemical fertilizers energy 12,900.69MJ ha–1
(43.15%), electricity energy 6698.27MJ ha–1 (22.41%), irrigation water energy 4142.05MJ ha–1 (13.86%), human labour
energy 1826.29MJ ha–1 (6.11%), chemicals energy 1660.69MJ ha–1 (5.56%), diesel fuel energy 1479.26MJ ha–1 (4.95%),
machinery energy 1134.65MJ ha–1 (3.80%) and organic fertilizers energy 51.45MJ 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, 1.02MJ kg–1, 0.98 kg MJ–1 and 25,837.74MJ ha–1. Benefit-cost ratio was calculated as 2.02 for nectarine production.
