- Faba bean (Vicia faba L.) is economically an important crop in Ethiopia. The productivity of Faba bean in Ethiopia has been declined due to poor management practices of inappropriate fertilizer rate and Bio fertilizer rates usage. Factorial combination of five rates of Blended fertilizer (0, 60, 121, 180 and 240 kgha-1 NPSZnB) and three rates of Bio fertilizer (0,500 and 750 gha-1) treatments were laid out in RCBD with three replications. Days to 50% flowering, days to 90% physiological maturity, plant height, number of productive tillers, total biomass yield, numbers of pods per plant, number of nodule per plant, effective nodule, grain yield and straw yield were recorded and significantly affected by the main effects. On the other hand, days to 50% flowering, plant height, effective nodule, grain yield and number of seed per pod were significantly affected by the interaction effect of Blended and Bio fertilizer rates. The maximum grain yield (3278 kgha-1) was recorded from combined 180 kg ha-1 blended fertilizer and 750gha-1 bio-fertilizer treatment. About 180kgha-1 Blended fertilizer rate and 750 gha-1 Bio fertilizer rates were preferable for the study area. However, further study has to be done under different seasons and locations to come up with workable recommendations related to the present study.
