Comparative Analysis of Energy Use Efficiency and Greenhouse Gas Emission of Wheat Farming in Edirne Province of Türkiye

Abstract

This study aimed to determine the energy use efficiency and greenhouse gas emission of wheat production in enterprises that had soil analysis or not. A survey was conducted with 60 producers who had soil analysis in three laboratories in Edirne province, which accepted the most sampling for soil analysis and gave fertilizer recommendations in 2015 and 40 producers who did not have soil analysis in the same region. Thus, a total of 100 producers were interviewed. Energy use efficiency, energy productivity, specific energy and net energy were 3.54, 0.20 kg MJ-1, 5.09 MJ kg-1 and 60191.34 MJ in the enterprises that had soil analysis, respectively. On the other hand, these values were 3.19, 0.17 kg MJ-1, 5.74 MJ kg-1, and 54508.49 MJ in the enterprises that did not have soil analysis. Greenhouse gas (GHG) ratios per kg were found as 0.66 and 0.72 for the wheat production in the enterprises that had and did not have soil analysis, respectively. In the enterprises that had soil analysis, the shares of the chemical fertilizers in energy use and total GHG emissions were lower than the other producer group. As a result of the analysis, it was determined that wheat production in the enterprises that had soil analysis was more efficient in terms of energy use and greenhouse gas emissions compared to enterprises that did not have analysis and these results revealed the importance of having soil analysis and applying fertilizer amounts according to soil analysis results.
