DETERMINATION OF ENERGY UTILIZATION EFFICIENCY AND GREENHOUSE GAS (GHG) EMISSIONS FOR FORAGE PEA PRODUCTION AT MUS PROVINCE IN TURKEY

The study's goal is to assess the energy balance of fodder pea crop production.and greenhouse gas (GHG) emission under Mus conditions, Turkey in 2020. Basic information such as the economic life of the instruments and machines utilized in the study, work success, fuel-oil consumption, machine weights and the amount of used fertilizer and seed were obtained by current measurements, from other studies, various sources and catalogs. The evaluations resulted in the determined energy output/input ratio, the specific energy value, and energy productivity. and the net energy efficiency values for feed pea crop production were 5.10, 3.65 MJ kg-1, 0.27 kg MJ-1 and 35636.85 MJ ha-1, respectively. The fertilizer energy had the highest energy utilization rate of the overall energy inputs for feed pea production, with 31.35%.. This was followed by seed energy with 25.77%, fuel energy with 21.40%, machine energy with 14.93% and human energy with 6.55%, respectively. Total GHG emission for forage pea crop production was calculated as 1533.81 kgCO2-eqha-1. The highest share in total GHG emissions was at seedconsumption (59.69%). The seed was followed by human labor (13.23%), nitrogen fertilizer consumption (9.12%), phosphate fertilizer consumption (6.02%), machinery use (6.0%) and diesel fuel consumption (5.94%). Furthermore, the GHG ratio in the production of fodder pea crops was calculated to be 0.65 kgCO2-eqkg-1. As a result, fertilizer energy had the biggest share of production inputs, followed by seed, fuel, machinery, and human labor energies, respectively. Total GHG emission and the GHG ratio was calculated as 1533.81 kgCO2-eqha-1 and 0.65 kgCO2-eqkg-1, respectively.
