Design of any farm machineries like thresher, conveyor, seed drills, harvester, and processing equipments, requires a thorough understanding of the engineering properties of seeds. The engineering properties of seeds also vary with moisture content of the seeds. In this study, the effect of moisture content on engineering properties of buckwheat seeds was studied. Total of fourteen properties were examined at three different moisture content levels i.e., 16%, 18% and 20% (d.b.). It was observed that the value of physical properties viz., length, width, thickness, geometric mean diameter, arithmetic mean diameter, surface area, sphericity increased with the increase in moisture content. The thousand seeds weight increased with moisture content but the densities were found to decrease with increase in moisture content, indicating higher rate of volume expansion due to moisture absorption by the seed. The engineering properties such as angle of repose decreased, while the terminal velocity increased with increase in the moisture content. However, the static friction co-efficient were found to slightly increase but the effect of moisture content was not significant within the studied moisture range. The above study provides vital information for design and development of machine for efficient post harvest operation of buckwheat seeds.
