Abstract: Some selected physical properties of sorghum crop such as grain length, width, thickness, surface area, sphericity, roundness, angle of repose, thousand kernel weight (TKW), specific gravity, bulk density and porosity were determined. The relationships of these properties with moisture content were also presented. From the results, the kernel volume and other dimensions such as length, width and thickness increased with increase in grain moisture content. Comparative evaluation of the two varieties of sorghum (farafara and short kaura) on the above properties shows that only the difference in the means of a thousand kernel weight (TKW) and angle of repose (grain to glass) are the parameters which are statistically significant at 5 percent level of significance. The result also revealed that parameters such as length, width, thickness and volume of grain increased with increase in moisture content. Correlation coefficient between 86.6% - 97.9% were obtained with the relationship between moisture content and grain length, grain width, grain thickness and grain volume for both varieties.
