Harvesting and Threshing of Maize with Combine Harvester

This study was conducted to evaluate the performance of maize combines having different types of headers i.e. snap roll type header and cutter bar type header. The mean forward speed and mean field capacity for cutter bar type header type header was 2.10 km/hr and 0.30-0.40 ha/hr, respectively while mean forward speed and mean field capacity for snap roll type header was 1.50 km/hr and 0.20-0.30 ha/hr, respectively. Shattering loss in snap roll type header combine was 12.50 to 18.50 per cent while shattering loss in case of cutter bar type header was 5.00 to 10.50 per cent.
