- For increasing high productivity of soybean should be found precise combination biofertilizers between arbuscular mycorrhiza and Rhizobium. The experiment was conducted using block split design, three replications. Three genotypes of soybean, Ceneng, DS1 and Pangrango were inoculated with Glomus manihotis + Rhizobium sp. TER 2.2 (GimR1), Gi. margarita + Rhizobium KLB 5.3 (GlmR2), Gigaspora margarita + Rhizobium TER 2.2 (GimR1), Gi. margarita + Rhizobium KLB 5.3. (GimR2) and inorganic fertilizers as a control (100 kg ha-1 N, 80 kg ha-1 P205 and 100 kg ha-1 K2O). All treatments were given green manure with the dosage equivanent to 1 ton ha-1 dry weight. First fertilizer was applied on inoculant treatment 25 kg ha-1 N (Urea), 20 kg P2O5 (SP36) and 100 kg ha-1 K2O (KCl). The results of this experiment revealed that Ceneng followed by Pangrango and DS1 was the most responsively soybean genotypes for CMA + Rhizobium tested. CMA Gigaspora margarita was more superior than Glomus manihotis and Rhizobium KLR 5.3 was more superior than Rhizobium TER 2.2 for increasing soybean growth and yield. Three symbiosis soybean-CMARhizobium were determined by soybean genotype, CMA species and its Rhizobium isolates. Combinations of GlmR1, GlmR2, GimR1 and GimR2 were potential combinations for increasing soybean growth and yield the same as or more than inorganic fertilizers. Dry season and Fe and Mn ions had negative effects for CMA and Rhizobium combinations in increasing soybean growth and yield compared with inorganic fertilizers.
