A field experiment was conducted to study the effect of rhizobial inoculants and vermicompost on the yield and quality attribute of fababean (Vicia faba L.) and some soil properties after planting. The experiment consists of seven treatments as follows: T1: control, T2: full recommended mineral fertilizer (RRN), T3: rhizobia inoculation, T4: 100% nitrogen from vermicompost, T5: rhizobia inoculation with 50% nitrogen from vermicompost, T6: rhizobia inoculation with 75% nitrogen from vermicompost and T7: rhizobia inoculation with 100% nitrogen from vermicompost. The experiment was conducted according to RCBD design with three replications. The results indicated that the use of rhizobia inoculation with vermicompost has improved some soil properties, growth, and yield parameters of fababean at all experimental sites. Rhizobia inoculation with 50% nitrogen from vermicompost was superior in most of the traits, including the number of tiller (3.83), number of pods per plant (26.56), number of seed per plant(54.20), biomass yield (13427.6 kg ha-1) and adjusted grain yield (4525.9 kg ha-1). Hence, the application of Rhizobium and vermicompost is needed to boost the productivity of faba beans and enhance soil fertility in the study site
