Abstract

Minor millets are small sized cereal grains belonging to the family Poaceae (Gramineae) are grown mainly in America, Japan, China and India. In India minor millet grown are finger millet, proso millet, barnyard millet, kodo millet and little millet. Threshing is based on the principle that, some impact is given on crops, the grains are separated from panicles, cobs and pods. The performance of the threshing unit with development of five different shapes of pegs for threshing small millet. small millet thresher was tested at two different speed 712 rpm and 1068 rpm. The highest threshing efficiency with disc shape peg of 99.57 % cleaning efficiency 98.64 % output capacity 19.68 kg/ha was observed. In disc shape peg seed damage negalible. The cost of operation was also minimum. On the basis of above the disc type pe is recommended for minor millet.
