摘要

Biasi (Beushening) is a traditional method of rice cultivation in rainfed risk prone areas of Eastern India. It is performed by animal drawn plough. The productivity of rice drastically reduces due to delayed Biasi operation by the use of animal drawn implement. Therefore, effort was made to develop a tiller-based rotary unit Biasi implement. Design considerations included soil condition during Biasi operation for Inceptisols and Vertisols soils [soil moisture content 60-65% (db) flooded, specific weight 14-18 kN/m~3 & Cone Index 48-54 kPa]. Accordingly, the cage wheel parameters (73 cm wheel diameter, 30 cm wheel width, 450 lug angle and 20 cm lug pitch) for Biasi operation were optimized. The rotary unit of a 13 hp power tiller was modified for Biasi operation. The rotary unit with 8 tines, 152 rpm rotor speed for 70 cm working width, blade distance 18 cm, length of soil slice 7-9 cm at 0.4 m/s forward speed was found suitable. The study revealed that the modified rotary unit of power tiller was found suitable for Biasi operation under rainfed rice cultivation because of their higher field capac- ity, better quality of work and higher benefit cost ratio as compare to traditional method.
