Evaluation of Energy Efficiency of Different Sowing Methods in Grain Corn Production

Abstract

In the study, the mean germination time (MED) was determined as 16.6 days, 21.08 days, and 9.75 days in the conventional sowing method, cross double row sowing method and parallel double row planting method, respectively, and the germination rate index (ERI) in the same order. It was found as 0.31 - 0.52 - 0.40 pieces/m day. Grain yield was 15260 kg/ha in conventional sowing method, 22330 kg/ha in cross double row sowing method and 18300 kg/ha in parallel double row sowing method. As a result of the experiments and calculations, the net energy yield was found to be 297.353,23 MJ/ha, 238.986,57 MJ/ha, 194.782,97 MJ/ha, respectively, then the cross-double row planting method, parallel double row planting method and conventional planting method. The maximum energy efficiency was obtained in the cross-double row planting method as 0.79 kg/MJ, followed by the parallel double row planting method and the conventional planting method with the values of 0.66 kg/MJ and 0.55 kg/MJ, respectively. The maximum output/input ratio was found in cross double row planting with 11.54%, then parallel double row planting with 9.59% and conventional planting with 8.03%. This study reveals that the cross-planting method is more advantageous than other methods and that this method can be used economically.
