Karacadağ yöresinde biçerdöverle çeltik hasadında dane kayıplarının belirlenmesi

Abstract

Karacadag region of Diyarbakir province is one of the important paddy production regions of our country. Mechanization practices in paddy agriculture in the region are quite new. So, grain losses are high during harvesting with combine harvester. The main purpose of this study was to determine the grain losses, causes and ways of reducing the grain harvesters used in the paddy harvesting-threshing harvesting in Karacadag region. The experiments were carried out in three different periods in the field where a Karacadag white variety belonging to a producer was planted; three different grain moisture content (22.10%, 24.81 and 28.81 crop moisture content), three different combine forward speeds (1.6 km h-1, 3.2 km h-1 and 4.8 km h-1) and four different drum speeds (600, 700) , 800 and 900 min-1). NEW HOLLAND TC 56 combine harvester was used in the trials. The analysis of variance the main effects of moisture content, forward speeds and drum speed significantly affected grain losses. Test results indicated that total grain losses decreases with increase moisture content and drum speed. Also, forward speed has been increased the total grain losses. When the effect of all testing combination was evaluated together, the lowest total grain loses was found at 28.85% moisture content, 4.8 km h -1 forward speed and 900 min -1 drum speed as 4.0% while the highest total grain loses was found at 24.81% moisture content, 3.2 km h -1 forward speed and 600 min -1 drum speed as 16.97%.
