A pot experiment using soil from Bone-Bone, South Sulawesi, Indonesia classified as inceptisol was carried out in the glass-house to know the effect of four strains of Bradyrhizobium japonicum with or without the application of P together with Mo and Cu on root nodule formation and N or P uptake of soybean plants. The experiment was conducted using a randomized complete block with 18 treatments replicated three times. B. japonicum strain THA 1 was less effective than strains TAL 102, 377 and 379. The effectiveness of the Bradyrhizobium was improved by P. Without P, infection was poor. Inoculating soybean with B. japonicum with the application of P followed by Mo and Cu did not improve root nodule formation.
