Determination of Effects of Cleaning fan speed and forward speed on Grain losses during the rapeseed harvesting by combine

Grain losses during the rapeseed harvest by combine are important level that rapeseed is an important oil plant. Grain losses have been reaching up to 20-30 % during the harvest because of both its 1000 kernel weight varies 2.5-5.5 g that its grains are pretty small and its cultivation techniques haven’t been known by the farmers exactly. It has been aimed to determine the effects of cleaning fun speed and forward speeds on grain losses during the rapeseed harvest by combine in this study. For this purpose, field experiments were conducted in experiment fields of the Black Sea Agricultural Research Institute in Samsun between the years 2007-2010. Combine having 4.8 m working width were used in the experiments. The rapeseed cultivar Elvis was used in the research. The study was designed in split parcels in randomized blocks. Studies were conducted according to 3, 4 and 5 km.h-1 forward speeds and 400, 500, 600 rpm cleaning fun speed. As a result of the study it was established that the most available forward speed was 4 km.h-1 and cleaning fan cycle was 500 rpm.
