Energy use, greenhouse gas emission and economic analysis in sour cherry production: the case of isparta province

This thesis study aims to determine the energy use efficiency, greenhouse gas emission and economic efficiency in sour cherry production. Within the scope of the study, total energy input, total energy output, energy use efficiency, specific energy, energy productivity, net energy, greenhouse gas emission, direct energy inputs, indirect energy inputs, renewable energy inputs, non-renewable energy inputs and economic balance calculations were made with respect to sour cherry production. With the subsequent economic analysis, the profit and cost conditions were revealed by determining the economic efficiency of the sour cherry production farms. In cherry production, total energy input was calculated as 14 143.79 MJ/ha, total energy output as 21 630.75 MJ/ha, energy use efficiency as 1.53, specific energy as 1.92 MJ/kg, energy efficiency as 0.52 kg/MJ and net energy value as 7 486.96 MJ/ha. Energy inputs in sour cherry production consist of direct energy with 8 207.24 MJ (%58.03), indirect energy with 5 936.55 MJ/ha (%41.97), renewable energy with 2 590.73 MJ/ha (%18.32) and non-renewable energy with 11 553.06 MJ (81.68%). Total greenhouse gas emission 479.73 kgCO2-eq/ha and greenhouse gas emission ratio 0.06 kgCO2-eq/kg were calculated. The total cost incurred in the production of sour cherry was 39 818.84 TL, the amount of sour cherry produced was 7 382.51 kg and the production cost of 1 kg of sour cherry was 5.39 TL. According to the profitability indicators of sour cherry farms on enterprise basis, gross production value was calculated as 64 375.49 TL, variable costs 23 891.30 TL, fixed costs 15 927.54TL, production costs 39 818.84 TL, gross profit 40 484.19 TL, net profit 24 556.65 TL and relative profit 1.61.
