STUDY OF TILLAGE AND PERFORMANCE EVALUATION OF ZERO SEED DRILL

The performance evaluation of zero - seed - drill was carried out in an area of about 0.15 ha at Agricultural Engineering Farm of IFTM University Moradabad Uttar Pradesh. It was observed that there was no effect of stubble on the performance of zero - seed - drill. However, the loose straw spread on the surface offers some hindrance in the working of the drill. The standards test code was adopted. Each test was replicated minimum three times. Forward speed and depth and sowing were taken as independent variables while wheel slippage field capacity field efficienc y, fuel consumption bulk density after operation, wheel slippage& weed count were taken as dependent variables. The wheel slippage at 2.0 km/hr and 3.0 cm depth was found tube 2.2% (minimum) and was found to be 4.43%(maximum) at 3.0km/hr speed and 4.0cm d epth of sowing in case of the operation Field capacity was found to be highest of 0.2662 ha/h at 2.5km/hr. The bulk density was found to be 1.002 gm/cc (minimum) at 1.8 km/hr at 3.0 cm depth and maximum at 1.44gm/cc (maximum) at 2.5 km/hr at 4.0cm in case of operations. The distance between plants to plant was 11cm to 15cm after 45 days in maize and 10 to14 cm in ladyfinger after 45 days. Based on present study the following conclusions were drawn. The wheel slippage of drive wheel of tractor increased with increased in forward speed. It also increased with the increased in depth of operation. Field capacity increased with the increase in forward speed thereafter it decreased after the speed of 3 km/hr. Bulk density increased up to a depth of 4.5 after which it was increased with the increase in speed of operation.
