A COMPREHENSIVE STUDY ON PHYSICAL PROPERTIES OF BLACK GRAM AND GREEN GRAM FOR DEVELOPING A PLANTER
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2018, Vol 8, Issue 6
Abstract
For optimizing the structural parameters for optimum performance of seeder or planter depends on seed size and its uniformity. Selected important physical and mechanical properties of black gram variety VBN-3 and green gram variety CO-6 were studied and its importance in inclined seed metering mechanism development discussed. The digital vernier caliper was used to measure the major axis and minor axis of black gram and green gram seeds. Standard procedures were employed for measuring bulk density and angle of repose. The major axis and minor axis of the selected varieties of black gram and green gram seeds were 3.97, 4.25, 3.60 and 3.92 mm, respectively, were considered in the design of cells on the metering plate of pulse planter. The average 1000 seed weight and bulk density of black gram and green gram varied between 51 to 56 g, 46 to 51 g, 1389.68 to 1494.43 kg m-3, 626.56 to 984.29 kg m-3 respectively. The mean angle of repose and coefficient of friction over the surfaces of plywood, galvanized steel, mild steel and rubber was 28.64°and 0.605, 35.55°and 0.746, 24.26° and 0.592 and 39.57° and 0.706 respectively, were recorded for black gram and 26.3°and 0.676, 32.6°and 0.823, 26.8° and 0.486 and 38.5°and 0.865 respectively were recorded for green gram
