Abstract-- Design and development of seed box and other components of an inclined plate broad bed furrow planter has been done from the physical properties of hundred seeds of soybean and chickpea seeds viz., size (length, width, and thickness), geometric mean diameter, sphericity, thousand seed mass, bulk density, roundness, angle of repose. Popular varieties of soybean and chickpea seeds were used in this study namely AMS-MB-5-18 and AKG-1109 respectively which are suitable for high density planting system. Cell size of the seed metering plate was selected with reference to maximum breadth, width and length of seeds. Sphericity of soybean and chickpea seed ranged from 0.83 ± 0.007 to 0.74 ± 0.012 and thousand seed mass from 106.68± 2.061 to 211.93 ± 3.233 g respectively. Capacity of seed hopper depends on the bulk density of seeds. The bulk density for soybean & chickpea seeds varied from 748 to 779 kg m-3 and angle of repose varied from 30.96 to 31.25 degree respectively. To ensure free flow of soybean seeds, slope of the seed hopper was taken as 350 which is higher than the average angle of repose of seeds.
