An experimental study on strength properties of sorghum grain was conducted which are essential to design different post-harvest gadgets such as threshers, winnowers, and storage bins. Since most of the post-harvest operations of sorghum are accomplished within moisture content range from around 10.0% to 25.0% (wb) in India, the study was conducted within the moisture content range from 8.7% to 21.8% (wb). The tensile strength of stalk, pedicel and grain tip was determined at five levels of moisture content and three levels of test speed i.e. 50, 100 and 150 mm/min. The rupture force of sorghum grains was measured at four levels of test speed i.e. 5, 10, 15, 20 mm/min and five levels of moisture content. The cutting strength of stalk of four different diameters was measured at a test speed of 10 mm/min at three different orientations of stalk i.e. vertical, horizontal and at 45 º. This study showed that the tensile strength of stalk, pedicel and grain tip increased with increase in moisture content at all levels of moisture content and the rupture force of grain decreased with increase in grain moisture content at all levels of moisture content.
