Zewdu School of Engineering and Information Technologies, PO Box 1888, Adama, Ethiopia Tel: +251 911 828912/500267, telecommunicate: zewdu.abdi@adama-university.net ABSTRACT In this probe broadcast seminal fluiding of tef inseminate was considered. In order to predict tinge flight on and off record book, after developing a numerical relationship, simulation of particle movement on and off saucer of a reel disc was undertaken. The terminal velocity and coefficient of snarl promote of tef seed were determined experimentally in laboratory. intercommunicate distance of particle thrown off the disk was measured by alter different particle property (such as wet content, coefficient of friction, TGM and particle density) and machine parameters (such as cone lean and angular velocity). The projected distance of a particle increase with increase in wet content of seed, broadcaster alteration per minute and inclination of disc with the horizontal.

The increase in moisture content was associated with increase in coefficient of friction, which do cave in effect on-the disc particle motion. The increase in moisture content has influence also on thousand caryopsis mass, particle size, sphericity, particle density and coefficient of drag force which steamy off-disc particle trajectory. This investigation showed the possibility of victimization a spinning disc spreader in or der to broadcast tef seed, which could sup! ersede broadcasting of tef seed by hand manually. Broadcasting using spreaders resembles the farmers practice, which use manual broadcasting of seeds unlike seed drills, which involves rows.
