OPTMIZING THE PERFORMANCE OF PLOT SEEDER MACHINE TO SUIT WHEAT SEED PRODUCTION

The plot seeders have a variety of distribution systems makes it possible to distribute the seed for a plot over multiple rows and many options allows you to customize the machine for many different applications. So when used a plot seeder to suitable for cultivation of wheat seeds must adjustment transmission mechanism and a feed cartridges diameter, as well as seeding shaft and distributor cone rotates. This study carried out to improve the performance of plot seeder and minimize the total damage during wheat seed production processes. The treatments under this study were at four diameters of feed cartridges (10, 15, 20 and 25 mm O), two kinds of distributor plat (distributor plat with and without partition)and three groups of sowing transmission. The variation coefficient of seeds and seeds damage were measured. The seeds damage generally increased with the decrease of feed cartridge from 15.6% at feed cartridge diameter (10 mm O) to 2.4% at feed cartridge diameter (25 mm O). Also seeds damage increased with distributor plat with partition. That was 15.6% with distributor plat with partition and 14.6% without partition. The variation coefficient of seeds decreases at diameter of feed cartridge (20 mm O) with distributor plat without partition and the first group of sowing transmission.
