Paddy is major crop of India. The grain to straw ratio in paddy crop is 1:1.25 and paddy crop generates huge amount of biomass and it alone contributes 34 % to total biomass production in India. Mostly combines are used for harvesting the paddy crop. The end use of paddy straw is not yet wide spread either on farm or in industrial sector. Thus straw management in combine harvested paddy fields is a major problem in paddy fields.
To overcome this problem, it was proposed that paddy straw is first chopped and then incorporated in soil with minimum tillage efforts. The straw choppers cum spreaders are widely used for harvesting the paddy stubbles for large and small farmers. Keeping in view the research study was conducted in order to determine the performance of straw chopper cum spreader for harvesting the paddy stubbles in combine harvested fields instead of on farm burning of paddy straw. The machine was operated in the speed ranging from 2.5 to 3 km h-1 with cylinder speed of 1600- 2000 rpm and their effect on length of straw and fuel consumption was also studied. The results obtained from evaluation of straw chopper cum spreader for harvesting paddy stubbles showed that the size of chopped straw material and fuel consumption were 80 to 120 mm and 5.5 to 6 l h-1 respectively with 0.45 ha h-1 average field capacity of machine.
