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.

Development and performance evaluation of manually operated potato planter. The manually operated potato planter consists frame, ground wheel, transmission for seed metering device, seed box, metering mechanism, seed tube, furrow opener and handle. The speed of planter was 1.8 km/h and 2.5 km/h respectively. The moisture content of soil was 17.2%. in the field testing, It was observed that the effective field capacity was 0.0191 ha/h at the speed of 1.8 km/h . and the field efficiency was maximum i.e. 81.3 % at the speed of 1.8 km/h and minimum was 61.5% at the speed of 2.5km/h. The cost of planting by the planter was Rs. 1680 / - per hectare.

Bansagar Dam is an inter-state multipurpose large river basin project constructed at a place called Devalond in Shahdol district of Madhya Pradesh state. The dam is built on the Son River (Sonbhadrashila) in Madhya Pradesh. Devalond is located on the Rewa-Shahdol road, about 56 km from Rewa. The height of this dam is 67 meters. We have surveyed the villages which are partially or completely affected by the Bansagar dam, as any development program, as we know, has two stages of construction. There are positive as well as negative effects, so we survey the affected area to compare the pre and post position of the submerged area according to the hypothesis or previous assumption.
