A study on determination of energy productivity, greenhouse gas emissions and economic analysis in strawbery production (a case stuy batman province)

In this study, it was aimed to determine the energy use and greenhouse gas emission in strawbery production in Batman province. The main material of the study was the data obtained from 189 strawberry producers in Batman province and its districts by survey method. The average strawberry yield in the research area was found to be 36,846.37 kg/ha Total energy input in strawbery production was found as 47.060,93 MJ/ha and energy output was found as 70.008,10 MJ/ha. In strawbery production, energy use efficiency was 1.48, energy productivity was 0.78 kg/MJ, specific energy was 1.28 MJ/kg and net energy was 22.947,17 MJ/ha. The shares of direct, indirect, renewable and non-renewable energy sources were found as 38,57%, 61,43%, 18,92% and 81,08%, respectively. Total greenhouse gas emission was determined as 3.155,56 kg CO2-eq ha-1 and greenhouse gas emission rate was determined as 0.086 kgCO2-eq kg-1. It was concluded that fertilizer input had the highest share in strawbery inputs energy equivalents and greenhouse gas emissions. Since the energy use efficiency is higher than 1, it is possible to say that the inputs are used efficiently, but this ratio can be increased by using more efficient inputs.
