SUMMARY
A newly developed straw combine suitable for paddy and wheat crop was evaluated in PUSA – 1121 paddy variety for its performance and retrieval of paddy straw. The straw combine was evaluated at three levels of moisture content (20, 35 and 50 %) and three levels of cylinder speed (29.6, 31.4 and 33.2 m/s) and forward speed (1.7, 1.9 and 2.1 km/h) in terms of field capacity, field efficiency, fuel consumption, straw split and straw size. The response surface methodology (RSM) was adopted for multi response optimization of straw combine parameters. Based on results obtained through RSM, it was found that the optimum combination for harvesting of paddy variety PUSA– 1121 was found to be moisture content of 20 %, forward speed of 1.91 km h–1 and cylinder speed of 33.20 m/s.
