Abstract: The effect of de-awning on physical properties of paddy were evaluated as a function of grain moisture content at 5 levels ranging from 6.92 to 23.16% d.b. The average length, width, thickness, geometric mean diameter and sphericity of the grain increased from 10.19 to 10.27, .29 to 2.42, .84 to 1.93, .502 to 3.634 mm and 0.344 to 0.354, respectively, as the moisture content increased from 6.92 to 23.16% d.b. In the case of awned paddy, the thousand grain mass increased from 24.324 to 28.038 g, bulk density from 316.76 to 357.60 kg m-3, true density from 1326.2 to 1384.6 kg m-3 and the porosity decreased from 76.11 to 74.17, the angle of repose increased from 37.42 to 45.71°. The static coefficient of friction was significantly different on three structural surfaces namely, mild iron (0.464 to 0.511), galvanized iron (0.432 to 0.471) and rubber (0.496 to 0.558) at the moisture content range considered. In the case of de-awned paddy, the thousand grain mass increased from 23.980 to 27.734 g, bulk density from 546.10 to 593.00 kg m-3, true density from 1352 to 1397 kg m-3 and the porosity decreased from 59.62 to 57.55, the angle of repose increased from 34.46 to 42.68°, the static coefficient of friction increased from 0.434 to 0.518, 0.416 to 0.464 and 0.477 to 0.538 for mild steel, galvanized iron and rubber, respectively as moisture content increased from 7 to 23% d.b.
