| Some selected physical properties of five varieties of mung bean grain seeds (EBSUpant1, EBSUpant2, EBSUpant3, EBSUpant4, and EBSUpant5) grown by the Department of Crop and Landscape Management, Ebonyi State University, Abakaliki, such as geometric properties (linear dimensions, sphericity, geometric and arithmetic mean diameters and surface area), gravimetric properties (true density, bulk density and porosity) and frictional properties (angles of repose and coefficient of friction) were determined as a function of moisture content in the range of 8.59 to 21.48, 8.35 to 20.90, 8.48 to 21.20, 8.69 to 21.73, and 8.88 to 22.20 % (w.b.), respectively. The results showed that the mean values of all geometric properties increased with increasing moisture... |

| The thermal conductivity of agricultural seeds has been used as engineering parameter in the design of process and machines for drying, storing, aeration and refrigeration. The thermal conductivity of white and red pigeon pea seeds with changes in moisture content and temperature was investigated using the transient heat transfer method. The thermal conductivity of white and red pigeon pea seeds increased from 0.2387 to 0.3497 Wm-1k-1 , and 0.2375 to 0.3425 Wm-1k-1 respectively, as the moisture content increased from 5 to 35% w.b. Thermal conductivity of white and red pigeon pea seeds increased significantly (p<0.05) from 0.2643 to 0.3543 Wm-1k-1 , and from 0.2711 to 0.3311 Wm-1k-1 respectively, as temperature increased from 10 to 70 ℃.
