Abstract:
Engineering properties aids in developing agricultural machines and equipment for many agricultural operations including planting and drilling. Size, geometric mean diameter, sphericity, aspect ratio, bulk density, true density, porosity, thousand seed weight, angle of repose, coefficient of static friction and hardness are some engineering attributes that are vital in sowing machine were investigated in the present study. The grain length varied from 6.62 to 8.26 mm, with a breadth of 1.82 to 2.40 mm and a thickness of 1.42 to 1.84 mm. The 1000 grain weight ranges from 14.0 to 15.3 g, an angle of repose of 27.40 to 28.10 º. The average coefficient of friction values was 0.38 and 0.36 in plastic, 0.40 and 0.40 in glass, 0.42 and 0.46 in mild steel sheet, 0.47 and 0.45 in fibre, and 0.51 and 0.53 in plywood and a bulk density of 577.63 to 605.16 kgm-3, with a true density of 1000 to 1043.15 kgm^-3. The average values of moisture content, hardness of BPT 5204 and BPT 2766 paddy varieties were 9.10% (d.b.), 12.78 kg and 10.2% (d.b.), 13.17 kg respectively.
