dc.description.abstractPaddy is one of the most important crop for food security in India, contributing significantly towards providing food and livelihood for 130 million people. The area under paddy cultivation in India is around 44 million ha with production of 105 million tones in 2014 (Anonymous, 2015). The head feed combine (DSM 72) having loop type threshing mechanism was tested at Tohana in Fatehabad, Haryana for optimization of machine parameters viz., cylinder speed (14.42, 15.53 and 16.64 m s -1 ), forward speed (3.5, 4.0 and 4.5 km h -1 ) and crop parameter viz., grain moisture content (18.1 to 22.4 per cent) were studied in relation to threshing efficiency, cleaning efficiency and total grain losses for scented and non-scented paddy varieties. Moisture content of 18.1 per cent, cylinder speed of 15.53 m s -1 and forward speed of 4.0 km h -1 was found optimum for harvesting of scented paddy variety Pusa – 1121 and CSR – 30. Moisture content of 18.1 per cent, cylinder speed of 16.64 m s -1 and forward speed of 4.5 km h -1 was found optimum for harvesting of non scented paddy variety HKR - 127 and HKR - 47. Moisture content was the most important factor influencing threshing efficiency, cleaning efficiency and total grain losses followed by cylinder speed and forward speed in all scented and non scented varieties. The average threshing efficiency varied from 99.76 to 99.81 per cent, whereas cleaning efficiency varied from 99.14 to 99.16 per cent in scented paddy varieties. The average threshing efficiency varied 99.62 to 99.72 per cent, whereas cleaning efficiency varied from 98.95 to 99.14 per cent in non scented paddy varieties. The total losses varied from 1.43 to 1.64 per cent in scented and 1.34 to 1.45 per cent in non scented paddy varieties at optimum parameters. The cost of operation was Rs 2772 ha -1 and Rs 2625 ha -1 in scented and non scented paddy varieties, respectively at optimum parameters. The break-even point, pay back period and B:C ratio were found to be 340 and 603 hours, 3.22 and 5.71 years and 1.62 and 1.33 in scented and non scented paddy varieties, respectively. The head feed combine was found economical and viable in scented varieties. It was because of negligible breakage losses and less break- even point, resulted more beneficial for rice millers and farmers.en_US
