The aim of this research want to know the influence of the addition Rhizobium bacteria species, dose and combination both ofthem, on growth and production of soybean plant (Glycine max (L) Merr.). The experimental design of this research was factorial design4—2, 4 species of Rhizobium are R1 = Rhizobium japonicum, R2 = R. phaseoli, R3 = R. leguminosarum, R4 = mixture of R1, R2 andR3, and 2 dose of inoculan Rhizobium (D1 = 5 m/plant, and D2 = 10 ml/plant) with 1010 sel bacteria/ml and 5 replications. Independentvariable is species of Rhizobium, dose of inoculan Rhizobium and combination both of them. Dependent variable is dry matter, weightof nodules and dry weight of seeds. The harvest data was analyzed by Kruskal-Wallis Test using 5% level (a = 0.05) followed by Mann-Whitney Test. The result of this research show that species of Rhizobium, dose of inoculan Rhizobium and combination both of thempresent insignificant result (a > 0.05) on soybean growth and production, but the mixture of Rhizobium species with high level doseof bacteria, present better result than single species with low dose of bacteria.
