Abstract
Rice (Oryza sativa) is one of the leading and widely cultivated cereal crops in the world. India has the world‟s largest area under rice with 43 million ha and is the second largest producer next only to China with production of 104 million tonnes during 2015-16. The productivity of rice was around 24q ha-1 during the agricultural year 2015-16 (Anonymous, 2017). The tractor drawn paddy straw reaper was evaluated at farmers field in Ludas village of Hisar district for optimization of machine parameters viz., cylinder speed (550, 750 and 950 rpm), forward speed (1.0, 1.5 and 2.0 km h-1) and crop parameter viz., straw moisture content (20.4 to 49.5 %) in relation to field capacity, field efficiency, fuel consumption, straw size, straw recovery and straw split percentage for paddy varieties Pusa-1121 and Pusa-44. For the paddy variety Pusa-1121 the field capacity, field efficiency, fuel consumption and power consumption at optimum conditions were 0.23 ha h-1, 66.37%, 5.33 l ha-1 and 21.82 kW, respectively. The straw size, straw recovery and straw split at optimum condition were 3.30 cm, 65.11 % and 89.11 %, respectively. Similarly for paddy variety Pusa-44, the field capacity, field efficiency, fuel consumption and power consumption at optimum conditions were 0.20 ha h-1, 59.45%, 5.67 l ha-1 and 23.70 kW, respectively. The straw size, straw recovery and straw split at optimum condition were 3.46 cm, 62.89 % and 86.23 %, respectively. Moisture content of 20.4-20.8 per cent, forward speed of 1.5 km h-1 and cylinder speed of 950 rpm was found optimum for paddy varieties Pusa-1121 and Pusa-44. The cost of operation was Rs 5190 ha-1and Rs 6112 ha-1 in Pusa-1121 and Pusa-44 variety, respectively. The machine was found economically feasible for the farmer‟s.
