Hasat Kaybı Ölçüm Yöntemlerinin Karşılaştırılması

Abstract

The aim of the study is to compare the 3 different methods that used to measure harvest losses under real field conditions for corn, soybean and cotton. A 1 m2 frame parallel to the planting row spacing (Method 1: M1), 1 m2 frame perpendicular to the planting row spacing (Method 2: M2) and three quarter m2 (Method 3: M3) were used to calculate harvest losses. This M1, M2, and M3 methods were used to calculate the losses in the harvest of corn and soybean with combine harvester. Then the M1 and M2 methods were used to calculate the losses when harvesting cotton with a cotton picker. 5 grids were established in the same field measuring 50mx50m for the M1, M2 and M3. The losses measured for corn at the end of the study were 2.8%, 3.4% and 4.7%; 1.5%, 2.1% and 4.4% for soybean respectively, according to M1, M2, and M3 methods. The losses measured for cotton 4.7% and 4.6%, respectively, according to M1, M2 methods. It was determined that losses calculated from the M1 to the M3 increased and that there was a difference in the calculated losses by 59.6% between the M1 and M3 for corn and 33.5% for soybean. There was no difference between the M1 and M2 for cotton.
