Abstract: Seed size and its uniformity are very important factors considered in design and development of any type of seed planter. The physical and mechanical properties like sphericity, thousand seed weight, bulk density, true density, angle of repose and coefficient of static friction of onion seed relevant to design of metering mechanism of a planter were determined. The average length, width and thickness were 2.85, 2.11 and 1.63 mm, respectively. The mean geometric mean diameter, sphericity and roundness of onion seed were 2.132 mm, 0.75 and 0.70, respectively. The bulk density varied from 0.636 to 0.642 g cm-3 and true density varied from 0.163 to 1.215 g cm-3. The mean porosity of onion seed was 46.22 per cent. The thousand seed weight of seed ranged from 3.502 to 3.664 g. The angle of repose varied from 37.23 to 40.69 degrees. The coefficient of static friction was determined on four different materials namely, aluminium (0.36-0.40), MS sheet (0.53-0.57), GI sheet (0.32-0.36) and SS sheet (0.28-0.32).
