dc.description.abstractIn this study, mathematical models were developed for pre-harvest loss, header loss, grain breakage, threshing efficiency, threshing loss and fuel consumption for wheat and paddy crop harvested by combine harvester. The data was taken from commercial test reports of twenty-five combines tested at Northern Region Farm Machinery Training &Testing Institute, Hisar. Regression analysis was carried out for developing mathematical models for the afore said variables depending on the independent variables such as crop yield, moisture content of the grains at the time of harvesting, forward speed of the combine, threshing drum speed, and field efficiency. The developed models were tested for their validity with the actual performance of the combines and the developed model for header loss of wheat was compared with existing model given by Audsley and Boyce. The developed model was found more efficient. With the help of developed models various dependent variables such as pre-harvest loss, header loss, grain breakage, threshing efficiency, threshing loss and fuel consumption can be predicted while operating with a combine in a particular field. The total crop residue of wheat and paddy in Haryana was also estimated. It was 44.27 and 24.6 lacks tones respectively for wheat and paddy.en_US
