Determining energy and tilization efficiency of different tillage methods on cotton cultivation under Menemen plain conditions

Cotton, an important industrial crop in agricultural sector, is the raw material for cotton textile, yarn production and oil industry, also of great significance in domestic and foreign trade. By carrying out energy and cost analyses on different agricultural practices applied in cotton cultivation, energy equivalence of inputs per unit area, energy efficiency of the crop, total costs and profit have been calculated. Thisdata has been acquired from the experimental plots with three repetitions on four different methods. The highest energy input is 15.545,81 MJ/ha in Traditional Tillage, while the lowest is 13.564,15 MJ/ha in Direct Drilling. When energy outputs compared, it's been understood that the highest energy output is in Traditional Tillage which has the highest yield and the lowest energy output is in Direct Drilling, which has the lowest yield. According to the experiments the highest energy ratio is 4,38 in Traditional Tillage, followed by Reduced Tillage with the ratio of 3,99 and Direct Drilling with the ratio of 3,93. The lowest energy ratio is found in Reduced Tillage 1 with the ratio of 3,72. It can be stated that a more efficient cultivation method is used in tillage methods with higher energy ratios. This study shows that in order to increase energy efficiency, first it is imperative to reduce the inputs and increase agricultural machinery in agricultural production.
