Popis: The aim of this research was to investigate the energy input-output analysis of apple produced in Karaman province of Central Anatolian Region in Turkey. This research was conducted at the apple cultivating facilities during the 2016 and 2017 production seasons in Karaman province. Production data of this research were collected in 2018. In order to determine the energy use efficiency of apple cultivation, various surveys were conducted at the 180 apple farms located in Karaman and selected through Simple Random Sampling method. The data were collected by face to face questionnaires and observations. The agricultural input and output energies used in apple cultivation were calculated to determine the energy input-output analysis. The energy input and output values in apple production were calculated as 78,378.08 MJ ha−1 and 99,959.60 MJ ha−1, respectively. Based on these research findings, the energy inputs in apple cultivation were 15,364.70 MJ ha−1 (19.60%) chemical fertilizers energy, 31,623.70 MJ ha−1 (40.35%) diesel fuel energy, 13,864.40 MJ ha−1 (17.69%) chemicals energy, 6998.40 MJ ha−1 (8.93%) machinery energy, 5738.88 MJ ha−1 (7.32%) human labor energy 2016 MJ ha−1 (2.57%) irrigation water energy and 2772.00 MJ ha−1 (3.54%) electricity energy, respectively. Yield output energy of apple production was calculated as 99,959.60 MJ ha−1. The energy productivity, specific energy, energy use efficiency and net energy calculations were also calculated as 0.54 kg MJ−1, 1.84 MJ kg−1, 1.28 and 21,581.52 MJ ha−1, respectively.
