Abstract

One of the oilseed rape problems is pre-harvest and harvesting grain losses due to uneven maturation of the pods. This experiment was conducted in order to evaluate the losses of different harvesting methods. A split plot experiment based on randomized complete block design with three replications was used. The main plots concerning harvesting methods were as: windrowing in 35% grain moisture content (M.C.) and harvesting in 10% grain M.C., two stage harvesting in 15% and 10% grain M.C., harvesting in 15% grain M.C. and harvesting in 10% grain M.C. subplots concerning rapeseed varieties were: hyola 308, hyola 401 and R.G.S. 003. Grain losses rate was significant in both main plot and sub- plot and their interactive effects. The least and highest losses rate was in windrawing treatment (3.8%) and harvesting in 20% grain M.C. (23.2%), respectively. In harvesting in 20% grain M.C. treatment, the most losses were behind the combine in unthreshed pods form. The least and highest rate of losses were observed in R.G.S. 003 (11.8%) and Hyola 401 (10.37%), respectively
