The present study was undertaken with five moisture levels (8%, 12%, 16%, 20% and 24%), whose effect was studied on gravimetric and frictional properties of ridge gourde seed. The gravimetric properties such as thousand grain weight, single grain weight and porosity increased linearly with increase in moisture content from 8 to 24% except bulk density and kernel density showed a decreasing trend. The frictional properties such as angle of repose and coefficient of static friction also increased linearly with increase in moisture content. The thousand grain weight, volume of single grain, bulk density, kernel density and porosity of ridge gourd were found to be 137.65 gm, 0.145 cc, 0.666 gm-cc-1, 1.124 gm-cc-1 and 40.75% respectively. The angle of repose was 24.160 and coefficient of static friction varied between 0.40 to 0.47 (due to various surfaces). The relationship between moisture content and various gravimetric and frictional properties was also established.
