Development and Performance Evaluation of Tractor Drawn Groundnut Planter for rabi Season
Subscribe/Renew Journal
An eight row tractor drawn planter was developed for sowing of groundnut seed in irrigated (Rabi) condition at Agricultural Research Station, Anantapur. The seed metering in the planter is of inclined plate type. Power is transmitted from ground wheel to metering system through chain and sprockets. A double point shovel type furrow opener was provided for opening the furrows. The seed is placed in the furrows at desired depth. The implement can be operated by a 35 hp tractor. During evaluation the field capacity of the planter was found to be 0.35 ha/h at the average speed of operation of 2.88 km/h with field efficiency of 66.5 per cent. It was found that, the cost of sowing with local manual seed drill was observed to be 51 per cent higher than the sowing with groundnut planter. Manual seed drill required 11.3 man-h/ha more than the groundnut planter.
