ABSTRACT
Recognition of effective factors and using suitable mechanism of crop harvesting can reduce seed losses to an acceptable amount. To investigate wheat crop losses due to seed moisture content and the speed of combine harvester at seed harvest time, research was carried out in G.B.P.U.A. & T., Pantnagar in 2003. This study included three seed moisture contents (10%, 15% and 20%) and three combine working speeds (1, 2 and 2.5 km/h) based on split plot by using a randomized block design with three replications. Finally combine working speed of 1.5 km/h and 9.16% crop moisture content was suitable for harvesting wheat crop. Stepwise regression technique was used to develop combine losses, seed breakage, performance and threshing efficiency models from field data. The r² value for seed breakage, performance efficiency and threshing efficiency were 0.888, 0.676 and 0.803, respectively.
