The research was conducted on Effect of moisture content on physical properties of maize grains (Zea mays L) was investigated in College of Agricultural Engineering during the year 2012-2013. The physical properties of the grain samples were determined at the desired moisture content levels of 12, 14, 16, 18 and 20 (% w.b.). The average three axial dimensions, sphericity, surface area, volume, thousand grain weight, true density, porosity and the static coefficient of friction were found to be increased and the bulk density was found to be decreased with increase in moisture content from 12 to 20 (% w.b.); all at an average temperature of 30°C. All these properties followed an increasing trend with the increase in moisture content, each showed a high correlation coefficients.
