Physical and Mechanical Properties of Talaja Red Onion Cultivar

The physical and mechanical properties of the onion crop were determined for the Talaja Red variety. The linear relationship was observed between polar diameter and equatorial diameter and also weight of the bulbs. The shape of the onion crop may be considered oval to spherical. The mean bulk density onion was observed 548 kg/m 3 . The coefficient of friction for galvanized iron, mild steel, aluminum and plywood was found 0.42, 0.39, 0.45 and 0.32 respectively. Also, the angle of repose for galvanized iron, mild steel, aluminum and plywood was found 23, 21, 24 and 17 respectively.
