The engineering properties of some selected variety of maize (SM39, SM40 and Oba Super 6) which is needed in the design and development of a functional handling and processing equipment for the crop was studied. The seeds were bought from the Agricultural settlements in Ogbomoso South-Western Nigeria. The selected properties are size, shape, weight, true density, and bulk density, angle of repose, coefficient of friction, and moisture content. The results of the experiments showed that the mean length was between 8.7 and 9.78 mm; width, 7.69 and 8.26 mm; thickness, 4.11 and 4.60 mm; geometric mean diameter, 7.17 and 7.78 mm; equivalent diameter, 6.62 and 6.62 mm; unit weight, 0.22 and 0.24 g; true density, 954.25 and 1245 kg/m3; bulk density, 734.45 and 752.23 kg/m3, and angle of repose of the three varieties are between 29.20 and 36.60. While the average values of static coefficient of friction measured was between 0.39 and 0.49. The results from this experiment showed that the effect of varieties is significant on the engineering properties of maize. The results obtained from these studies will be useful for the design and manufacturing of operating system for handling and processing of different varieties of maize.
