Physical properties of paddy are necessary for the design of equipment to handle, transport, process and store of the crop. These properties are evaluated as a function of moisture content of grain. In this study, some physical properties of raw paddy are discussed briefly. The grain was tested for bulk density, sphericity, thousand grain weight, size, angle of repose etc were determined with variable materials at 12 % moisture content wet basis. The total 25 varieties of paddy grown in the

The mean length, breadth, thickness, size, surface area, sphericity, thousand grain weight, angle of repose and bulk density of eight fine variety was found as 8.09 mm, 2.07 mm, 1.70 mm, 3.04 mm, 36.15 mm 2 , 0.37, 14.28 g, 28.23 0 and 543.5 kg/m 3 respectively. The ten medium varieties of paddy were studied and found the mean length, breadth, thickness, size, surface area, sphericity, thousand grain weight, angle of repose and bulk density as 9.11 mm, 2.46 mm, 2.02 mm, 3.56 mm, 48.25 mm 2 , 0.39, 22.77 g, 29.82 0 and 562.9 kg/m 3 respectively. Also eight coarse varieties were studied and found the mean length, breadth, thickness, size, surface area, sphericity, thousand grain weight, angle of repose and bulk density as 8.95 mm, 2.77 mm, 2.04 mm, 3.70 mm, 50.98 mm 2 , 0.41, 26.02 g, 29.94 0 and 600.5 kg/m 3 respectively.
