Abstract:
Rice is the major staple food of Jharkhand. Jharkhand produces 2.88 million tonnes, in area of about 1.59 million hectare with average production of 1.81 tonne per hectare. Paddy cultivation involves different operations like sowing of paddy for seedlings growing, puddling, seedling uprooting & transplanting, weeding, spraying of insecticides/pesticides, harvesting and threshing. Among these operations paddy threshing is an important operation which is carried out manually. Paddy threshing is tedious, less efficient and expensive operation carried out manually by most small-scale farmer in Jharkhand. To address these problems pedal and motor operated threshers were tested and evaluated. These threshers were evaluated in laboratory as well as in field condition. Data were recorded and analyzed. The mean threshing capacity of foot and motor operated paddy thresher were 80.62 kg/hr and 238 kg/hr compared with manually threshing 52.27 kg/hr, respectively. The machine can be adopted by farmers to cost effective reduce the drudgery and cost of threshing by adopting either pedal or motor operated paddy thresherseed yield per plant. These traits may be considered for selection and to improve the yield of mustard genotypes.
