DETERMINING THE ENERGY USE EFFICIENCY (EUE) AND GREENHOUSE GAS EMISSIONS (GHG) OF CHICKPEA PRODUCTION

In this research, energy use efficiency (EUE), specific energy (SE), energy productivity (EP), net energy (NE), energy types, GHG emission and GHG ratio computations were determined. This research was conducted during the 2017-2018 production season in Karaman province of Turkey. Trials and research data computations include the 2017-2018 production season. Energy input (EI) in chickpea production were computed as 8223.94 MJ ha(-1), energy output (EO) was computed as 7686.88 MJ ha(-1). In chickpea production, 46.35% of the energy inputs consists of diesel fuel energy (3812.19 MJ ha(-1)). 22.39% consists of chemical fertilizers energy (1841.40 MJ ha(-1)), 18.84 % consists of seed energy (1549.04 MJ ha(-1)), 7.24% consists of machinery energy (595.51 MJ ha(-1)), 3.37% consists of chemicals (fungicide, insecticide) energy (276.84 MJ ha(-1)) and 1.81% consists of human labour energy (148.96 MJ ha(-1)). EUE, SE, EP and NE in chickpea production were computed as 0.93, 5.56 MJ kg(-1), 0.18 kg MJ(-1) and -537.06 MJ ha(-1,) respectively. The total energy input used in chickpea production can be classified as 48.17% direct, 51.83% indirect, 20.65% renewable and 79.35% non-renewable. Total GHG emissions were computed as 1073.72 kgCO(2)-eqha(-1) for chickpea production with the greatest input part for seed use (60.40%). The seed use followed up diesel fuel use (17.40%), nitrogen use (7.66%), phosphorous use (5.06%), labour use (4.95%), machinery use (3.94%), fungicide use (0.35%) and insecticide use (0.24%), respectively. Additionally, GHG ratio value was computed as 0.74 kgCO(2)-eqkg(-1) in chickpea production.
