Determination of Energy Use Efficiency and Greenhouse Gas Emission (GHG) of Cotton Cultivation in Batman Province: A Case Study from Beşiri District

In this research, the energy use efficiency (EUE) and greenhouse gas emissions (GHG) of cotton cultivation in Beşiri district Batman province Turkey were determined. This research was conducted through face-to-face surveys with 64 farms selected by simple random sampling method 2018-2019 season. The input (EI) output (EO) calculated as 52,302.62 MJ/ha 60,341.03 MJ/ha. Energy inputs consist electricity 19,948.86 MJ/ha(38.14%), chemical fertilizers 14,163.83 (27.08%), diesel fuel 13,218.49 (25.27%), irrigation water 2563.79 MJ/ha(4.90%), machinery 1071.14 MJ/ha(2.05%), chemicals 797.96 (1.53%), seed 291.46 (0.56%) human labour 247.09 MJ/ha(0.47%), respectively. Total can be categorized 68.79% direct, 31.21% indirect, 5.93% renewable 94.07% non-renewable. EUE, specific (SE), productivity (EP) net (NE) 1.15, 10.23 MJ/kg, 0.10 kg /MJ 8038.41 MJ/ ha, GHG 3742.59 kgCO2-eq ha-1 for greatest share taken nitrogen (26.19%). Nitrogen followed (24.73%), (18.48%), (17.31%), (5.04%), (2.93%), phosphorous (2.74%), (2.36%), potassium (0.19%) (0.03%), ratio value 0.73 kg-1 cultivation.
