Optimization of the operational parameters of an inclined plate type planter for soybean using response surface methodology

Abstract

The developed planter was tested in laboratory for optimizing of the performance parameters of the newly developed tractor operated inclined plate planter having combination of forward speed (2.5 km/h, 3 km/h, 3.5 km/h, 4 km/h) with seed plate opening (25%, 50%, 75%,) for soybean crop. Performance was analysed on the basis of miss index, multiple index, quality feed index and uniformity index. Response Surface Methodology was used to analyse output response and input variables and to find out the optimum operating condition for inclined plate planter. The optimized operational parameters were forward speed and seed plate opening and observed to be optimised at the forward speed of 3.43 km/h with 50 per cent seed plate opening. The RSM result shows that the machine satisfactory performed at optimum operating conditions for forward speed 3.43 km/h with 50 per cent seed plate opening to these values of output variables of 2.60 per cent, 6.69 per cent, 90.71 per cent and 76.07 per cent of miss index, multiple index, quality feed index and uniformity index were respectively for soybean.
