ABSTRACT
Physical properties of grains play role in quality assessment, processing and equipment design. A study was conducted to determine the physical properties of two commonly grown varieties of kodo millet grains with and without husk in the moisture content range 15.45-25.8% db. The mean values of physical properties such as length, width, thickness, sphericity, surface area, volume, true density, porosity, 1000 grains mass, static angle of repose and dynamic angle of repose increased with increase in moisture content. No significant impact of addition of moisture on sphericity of grains with husk was observed and bulk density decreased with increase in moisture. The grains with husk have high mean values of geometric properties than grains without husk. However, bulk density, true density and static angle of repose was higher in case of grains without husk than grains with husk. Between the millet variety, grains of ALT-1 variety have slightly high mean values of physical properties than TNS-86 variety.
