Knowledge on physical properties of seeds is one of the most important parameter before designing of agricultural machines or any other equipment. The variety of paddy seeds taken for the study was Karma Mahsuri and shape was cylindrical while variety of fertilizer taken for study was DAP granules and shape was round. The research work was carried out in the laboratory at the Department of Farm Machinery and Power, SVCAET&RS, IGKV, Raipur. The main aim of the study was to determine the physical properties of paddy seeds and fertilizer (DAP granules) which will be beneficial for designing of sowing related machines like Paddy drum seeders, seed drills and seed cum fertilizer drills. Test Parameters taken for the study were geometric dimensions of Paddy seeds and DAP granules i.e. Average length (L), width (W) and thickness (T), Geometric mean diameter (Dp), Sphericity (̉ۢ), Mass and Bulk density. The results showed that the average length, width and thickness of paddy seeds varied from 8.61 to 11.29 mm, 2.55 to 3.03 mm and 2.08 to 2.50 mm respectively while DAP granules varied from 5.43 to 6.39 mm, 4.74 to 5.29 mm and 3.10 to 3.30 mm respectively. The bulk density by Mohsenin method for paddy seed was observed as 603 kg/m3 whereas the average weight of 1000 paddy seeds sample was measured as 35 gm. The Geometric mean diameter (Dp) by Mohsenin method and Sphericity by Sahay and Singh method for paddy was 3.90 mm and 0.41 while for DAP granules it was 4.57 mm and 0.76 respectively.
