    Determination of energy usage and greenhouse gas (GHG) emissions in artichoke production
    (2024) Demir, Cihan; Baran, Mehmet Fırat; Eliçin, Ahmet Konuralp
    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.

    Energy use efficiency and greenhouse gas emissions (GHG) analysis of garlic cultivation in Turkey
    (Chinese Acad Agricultural Engineering, 2023) Baran, Mehmet Firat; Demir, Cihan; Elicin, Ahmet Konuralp; Gokdogan, Osman
    This study has been conducted with the purpose of determining energy use efficiency and greenhouse gas emissions of garlic cultivation during the 2020-2021 cultivation season in Adiyaman province of Turkey. Questionnaires, observations and field works were performed in 134 garlic farms in the region through simple random method. In garlic cultivation, energy input was calculated as 32 103.20 MJ/hm2 and energy output was calculated as 30 096 MJ/hm2. With regards to the three highest inputs in garlic production, 46.66% of the energy inputs consisted of chemical fertilizers energy (14 979.26 MJ/hm2), 11.29% consisted of farmyard manure energy (3625.71 MJ/hm2) and 10.48% consisted of human labour energy (3363.36 MJ/hm2). Energy use efficiency, specific energy, energy productivity and net energy in garlic cultivation were calculated as 0.94, 1.71 MJ/kg, 0.59 kg/MJ, and -2007.20 MJ/hm2, respectively. The total energy input consumed in garlic cultivation was classified as 27.19% direct energy, 72.81% indirect energy, 35.17% renewable energy and 64.87% non-renewable energy. Total GHG emissions and GHG ratio were calculated as 8636.60 kg CO2-eq/hm2 and 0.46 kg CO2-eq/kg, respectively.
