The present study was carried out to investigate effect of foliar application of micronutrients on yield and yield components of tef(Eragrostistef) Gemechis variety, in three districts; Boset, Adama and Dodota during 2014-2015. The trial was laid out in a randomized complete block design in three replicates. Seven treatments comprising chelates of four micronutrients viz., Copper (Cu), Zinc (Zn), Iron (Fe), and Manganese (Mn) separately, combination of these chelate micronutrients, with NPK (nitrogen, phosphorus and potassium), NP (nitrogen and phosphorus) and NPK were evaluated. The chelated blended type fertilizers were foliar applied at rate of 1.12 kg ha-1 in 600L of water with recommended rates of NPK (41N, 46 P2O5 and 60 K2O). The result revealed that at Melkassa and Adulala significantly high (p< 0.05) tef yield 1350 kgha-1 and 1991.7 kgha-1 were obtained by the application of Cu respectively. At Dodota significantly high (p< 0.05) tef yield 1920.8 kgha-1 was obtained by the application of Mn. At Wolenchiti plant height and panicle length significantly affected by the application of Zn and Mn however, the grain yield and biomass yield was not significantly affected by the foliar application of micronutrients. Partial budget analysis was also carried out to identify the rewarding treatment for economic production of tef, at Melkassa the application of NPK with or without micronutrients have no meaningful economic advantage over the recommended NP fertilizers. At Adulala and Dodota, the highest net benefit 26,757 and 25,736.5 ETBha-1 were obtained respectively with high Marginal Rate of Return (MRR) greater than 100% by the application of NPK with micronutrients.
