Abstract
This research sought to investigate how the yields of faba beans in farm settings in the Ethiopian district of SebetaHawase were affected by the co-application of an elite Rhizobium inoculant and vermicompost (VC). The study was conducted during the 2019/20 and 2020/21 cropping seasons. A randomized complete block design with three replications was used.   After two years of data analysis, the average result revealed a significant (P < 0.05) variation in all parameters among the treatments in the district. In the SebetaHawase district, rhizobial isolates FB-17 + 0.76 ton ha-1 of VC and FB-17 + 0.57 ton ha-1 of VC showed relative first and second superiority in terms of total nitrogen content (%), available phosphorus (ppm), and organic carbon (OC %). At SebetaHawase, the treatments with the highest mean grain yield (3349, 2873 and 2746 kg ha-1) was obtained with FB-17 + 0.76 ton ha-1 VC, FB-17 + 0.57 ton ha-1 VC, and FB-17 + 0.38 ton ha-1 VC. However, based on the findings of the partial budget analysis, the treatments FB-17 and FB-17 + 0.76 ton ha-1 VC at SebetaHawase had higher marginal rates of return (42848 and 1083% each).  To identify the best alternative bio-organic fertilizers for faba bean production in Ethiopia's Pellicvertisol zones, these treatments are believed to be excellent candidates for additional testing in farmers' fields across a range of agro-ecologies.
