A study on determination of energy productivity, greenhouse gas emissions in banana production (A case study Mersin province)

In this study, energy use and greenhouse gas emissions in greenhouse banana production in Anamur district of Mersin province were determined and gross profit analysis was conducted. The main material of the study was the data obtained from 251 banana producers by survey method. In order to calculate energy equivalents, the amounts of inputs used in banana production were found and these input data were multiplied by energy equivalent coefficients. The total banana production area in the research area was calculated as 210.30 ha and the average banana production area was calculated as 0.83 ha. The total production amount was determined as 16,195.00 tons and the average banana yield was 77,009.03 kg ha-1. Total energy input in banana production was 94,373.80 MJ ha-1 and energy output was 184,821.67 MJ ha-1. In banana production, energy use efficiency was 1.96, energy productivity was 0.82 kg MJ-1, specific energy was 1.23 MJ kg-1 and net energy was 90,447.87 MJ ha-1. The shares of direct, indirect, renewable and non-renewable energy sources were found as 26.81%, 73.19%, 24.08% and 75.92%, respectively. Total greenhouse gas emission was determined as 9,120.73 kg CO2-eq ha-1 and greenhouse gas emission rate as 0.118 kgCO2-eq kg-1. Gross production value, variable costs and gross profit were found as 847,099.33 TL ha-1, 256,318.63 TL ha-1 and 590,780.70.08 TL ha-1. It was concluded that fertilizer input had the highest share in energy equivalents, greenhouse gas emissions and variable costs in banana production. Energy use efficiency higher than 1 indicated that inputs were used efficiently.
