Determination of energy usage and greenhouse gas (GHG) emissions in artichoke production

Abstract

This study has been conducted with the purpose of determining the energy usage (EU) and greenhouse gas (GHG) emissions of artichoke production. It has been conducted in Efeler district of Aydın province of Türkiye during the 2022 production period. According to the results of the study, total input energy (EI) was calculated to be 32 211.48 MJ/ha and output energy (OE) was calculated to be 5 460 MJ/ha. EI in artichoke production were 15 718.20 MJ/ha (48.80%) chemical fertilizers energy, 8 896.98 (27.62%) diesel fuel energy, 3 832.27 (11.90%) machinery energy, 1 958.40 (6.08%) electricity energy, 1 036.35 (3.22%) irrigation water energy, 329.55 (1.02%) human labour energy, 294 MJ/ha (0.91%) plant energy and 145.73 (0.45%) chemicals energy, respectively. Energy use efficiency (EUE), specific energy (SE), energy productivity (EP) and net energy (NE) values were found as 0.17, 4.72 MJ/kg, 0.21 kg/MJ and -26 751.48 MJ/ha, respectively. The total energy inputs that were involved in artichoke production were classified as: 37.94% (12 221.28 MJ/ha) direct (IE), 62.06% (19 990.20 MJ/ha) indirect (IDE), 5.15% (1 659.90 MJ/ha) renewable (RE) and 94.85% (30 551.58 MJ/ha) non-renewable (NRE). Total GHG emission was calculated as 1 401.64 kgCO2eq/hafor artichoke production with the greatest share for diesel fuel (31.11%). GHG ratio value was calculated as 0.21 kgCO2eq/kg in artichoke production.
