AN OPTIMIZATION OF MACHINE AND OPERATIONAL PARAMETERS ON SEED PLACEMENT INDEX FOR PRECISION SOWING OF BLACK GRAM
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2018, Vol 8, Issue 6
Abstract
For achieving desired seed placement index for black gram variety VBN-3, a laboratory test rig was developed with the following independent variables. Cell geometry (S) - 3 levels -Maximum seed dimension - 4.25 mm, 10 per cent more than maximum seed dimension - 4.67 mm and 25 per cent more than maximum seed dimension - 5.31 mm. Inclination of seed metering disc () - 4 levels - 30, 35, 40 and 45. Peripheral speed of seed metering disc (V) - 4 levels - 0.1 ms-1, 0.15 ms-1, 0.2 ms-1 and 0.25 ms-1. From the experiments, it was inferred that the cell geometry with 10 percent maximum seed dimension registered maximum seed placement index. The angle of inclination of the seed metering disc had no profound effect on SPI for all levels of combination. At 0.20 ms-1 peripheral velocity of seed metering disc, the cell geometry 4.67 mm (10 per cent more than the maximum seed dimension) yielded higher SPI than the cell geometry of 4.25 mm and 5.31 mm.
