Özet

The purpose of this study is to determine the energy balance (EB) and greenhouse gas (GHG) emissions of pear producing. The study have been done in Niğde province in Türkiye. In this study have been calculated the energy use efficiency (EUE), specific energy (SE), energy productivity (EP), net energy (NE) and GHG emissions calculations of pear producing. The energy inputs (EI) in pear have been calculated as electricity 12,358.80 MJ ha−1 (49.64%), diesel fuel 2618.42 MJ ha−1 (10.52%), chemical fertilizers 2576.90 MJ ha−1 (10.35%), chemicals 2056.38 MJ ha−1 (8.26%), organic fertilizers 1575 MJ ha−1 (6.33%), human labour 1084.05 MJ ha−1 (4.35%), irrigation water 980.66 MJ ha−1 (3.94%), machinery 827.22 MJ ha−1 (3.32%) and transportation 819 MJ ha−1 (3.29%), respectively. Total EI of pear producing has been calculated as 24,896.43 MJ ha−1 and EO as 43,699.85 MJ ha−1. EUE, SE, EP and NE have been calculated as 1.76, 1.37 MJ kg−1, 0.73 kg MJ−1 and 18,803.42 MJ ha−1, respectively. The total EI in the producing of pear have been occurred as 68.45% direct energy (DE), 31.55% indirect energy (IDE), 14.62% from renewable energy (RE) and 85.38% from non-renewable (NRE) energy. The total GHG emissions and ratio resulting from pear producing have been calculated as 2668.42 kgCO2eq ha−1 and 0.15 kgCO2eq kg−1. According to the study results, the pear producing have been determined to be profitable in terms of EUE (1.76).
