A study was conducted to investigate the effect of reducing broadcast seeding rates on Tef yield and yield components during the 2013 cropping season in Ebinat District. A study was important to determine the optimum seed rate in order to increase Tef yields. A randomized complete block design (RCBD) with three replications was used to generate reduced seeding rates at nine levels: 5, 7.5, 10, 12, 5, 15, 17, 5, 20, and 25 kg/ha. The harvest indexes as well as the number of tillers, productive tillers, panicle length, biomass yield, straw yield, and grain yield were all strongly affected by seeding rates. On the other hand, the height of the plant, the number of spikelet’s, or the weight (mg) of 1,000 seeds had not changed significantly. It pertains to the fact that the number of tillers increases by 65%, and the length of the panicle increases by 3.63 cm when seeded at a rate of 5 kg/ha as compared to 25 kg/ha. Tef produced 10.7–22% higher biomass when sown at 5 kg/ha as opposed to the respective reduced seeding rates of 25 kg/ha. In general, broadcast seeding rates were used to generate steadily increased tef production in the Ebinat district.
