This study envisioned to assess the inoculation response of faba bean to six indigenous rhizobial isolates, 100 kg ha^-1 DAP as a positive control and non-inoculated negative control under farmers’ field conditions at Welmera district, Ethiopia. The results revealed the presence of significantly different treatments (p ≤ 0.05) in grain yield. The highest grain yields (3966 kg ha^-1and 3694 kg ha^-1) were obtained from inoculation of rhizobial isolates (FB-AR-13 and FB-1018) during the 2019/20 and 2020/21 cropping seasons. Based on the two successive year’s average grain yield response, FB-AR-13 (3966 kg ha^-1) became the first most performing isolate. The partial budget analysis results also showed that FB-AR-13 was the most promising isolate that showed a higher MRR 6422 %, which is 43% higher than the MRR of the local standard check FB-1018. Therefore, isolate FB-AR-13 is the best promising candidate for the development of commercial faba bean rhizobial inoculant in the central high lands of Ethiopia after further verification over different farmers' fields at different agro-ecologies. http://www.agriculturejournal.org/volume9number1/productivity-improvement-of-faba-bean-vicia-faba-l-through-elite-rhizobial-inoculants-in-the-central-highlands-of-ethiopia/ Faba Bean; Grain Yield; Inoculant; Strain
