A study was conducted to determine the physical and frictional properties of different varieties of different leguminous crops viz, moong, soybean, pea, kabuli gram, horsegram. It was observed that moisture content of different varieties of different leguminous crops ranged between 10.39-16.39% d.b. There was wide variation in the size among the varieties of selected leguminous crops. All selected leguminous crops were non-spherical in shape (Moong: 0.796-0.835, soybean: 0.820-0.846, kabuli Gram: 0.850-0.879, horsegram: 0.767-0.842) except pea which was nearly spherical (0.898-0.909) irrespective of the varieties. A significant effect of variety on bulk density was observed for all the leguminous crops except horsegram. A significant difference in true densities of moong, pea and horsegram varieties were observed while the varieties of other two crops showed non-significant difference in their true densities. There was varietal effect on porosity of all leguminous crops except moong. The variety has significant effect on hundred kernel weight. The moong, kabuli gram and horsegram variety showed remarkable variation in their frictional properties i.e., angle of repose, angle of internal friction, angle of external friction whereas, no variation was observed for pea and soybean. The angle of external friction of different leguminous crops on plywood surface was generally higher than G.I. sheet in all crops except moong which had an erratic trend.
