The purpose of this study is to evaluate the energy balance of organic olive production in Aydın-Karpuzlu Region in Turkey in 2015. In order to evaluate the energy input-output of organic olive, data has been provided by Aydın-Karpuzlu Organic Olive Producers Association. The agricultural input energies and output energies used in organic olive production have been calculated to evaluation the energy inputs and energy output. According to the research findings, the energy inputs in organic olive production have been calculated respectively as 19,426.95 MJ ha⁻¹ (50.31%) diesel fuel energy, 12,960 MJ ha⁻¹ (33.56%) machinery energy, polyethylene trap energy 3520 MJ ha⁻¹ (9.12%), 2116.80 MJ ha⁻¹ (5.48%) human labour energy, 276.48 MJ ha⁻¹ (0.72%) electricity energy, 231.60 MJ ha⁻¹ (0.60%) organic chemical energy and 81.87 MJ ha⁻¹ (0.21%) transportation energy. Total input energy has been calculated as 38,613.70 MJ ha⁻¹. Total output energy have been calculated as 104,888.78 MJ ha⁻¹. The energy output/input ratio, specific energy, energy productivity and net energy calculations have been calculated respectively as 2.72, 4.34 MJ kg⁻¹, 0.23 kg MJ⁻¹ and 66,275.08 MJ ha⁻¹ in organic olive production.
