Maize (Zea mays L) is one of the most versatile emerging cereal crops having wider adaptability under varied agro-climatic conditions. Pre and post harvesting operations are the most labour intensive operations that are presently done manually in India and need to be mechanized. The physical properties of seeds play an important role for designing seed metering device. Three varieties of maize seed PMH-1, PMH-10 and PIONEER-3396 were evaluated for their engineering properties in the laboratory. Therefore, the physical properties of the maize seeds such as size, shape, hundred grain weight, angle of repose, bulk density and coefficient of static friction are important from engineering point of view and were studied for the development of metering mechanism of maize planter. Fifty seeds of each variety (PMH-1, PMH-10 and PIONEER-3396) were tested and observed for shape and size of the seeds. During observations their geometric mean diameter comes out to be 7.33 mm, 7.06 mm and 7.68 mm for PMH-1, PMH-10 and PIONEER-3396, respectively. The average value of angle of repose during study was observed to be 28.59°, 27.10° and 28.66° for PMH-1, PMH-10 and PIONEER-3396, respectively. The roundness observed in the laboratory was 0.74, 0.74 and 0.66 and their sphericity was 0.78, 0.79 and 0.75 for PMH-1, PMH-10 and PIONEER-3396, respectively. Bulk density for the three varieties of maize was 733.88 kgm-3, 750.01 kgm-3, 741.27 kgm-3 and the value of Coefficient of static friction was 0.64, 0.58 and 0.55 for PMH-1, PMH-10 and PIONEER-3396, respectively.

Keywords: Maize, Physical properties, PMH-1, PMH-10, PIONEER-3396.
