Some Physical Properties of Samaru Sorghum 17 Grains

Abstract

Some physical properties of Samaru Sorghum 17(SAMSORG 17) were determined within the moisture range of 8.89-16.5 % wb being the moisture range for threshing and storage of sorghum. The diameter, one thousand weight and sphericity of the grain and and the sorghum grain mass, projected area, volume, particle density, and bulk density were the physical parameters measured. Results of the investigations showed that the average diameter of sorghum grain calculated by arithmetic mean, geometric mean and equivalent diameter methods were 3.32 mm and 3.31 mm, 3.31 mm and 4.20 mm, 4.16 mm and 4.18 mm at 8.89 % wb and 16.50 % wb respectively. The mean mass, projected area, volume, particle density and bulk density for sorghum grain were 0.044 g, 4.66 mm2, 0.091 cm3, 1.02 g/cm3 and 568.5 g/cm3 at 8.89 % wb respectively. The sphericity of sorghum grain was normally distributed about 0.92. The sorghum grain particle density decreased with increasing moisture content within the moisture range considered.
