Merrill] is easily introduced in places where it is not native, its production, especially Africa is constrained by the lack of Bradyrhizobium japonicum which is needed for biological nitrogen fixation (BNF). Inoculating soybean with proper rhizobacteria is a key solution to enhance benefits of BNF. A study was done in Northern Tanzania in Arusha and Kilimanjaro regions to assess the effects of B. japonicum, nitrogen (N) and phosphorus (P) application on four selected soybean varieties namely Uyole 1, Uyole 2, Uyole 3 and Uyole 4. Inoculation with B. japonicum strongly (P
