Application of arbuscular mycorrhizal fungi in combination with nitrogen fixing bacteria and other potential soil microbes as biofertilizer for soybean plant

The use of mycorrhizae as phosphate solubilizing fungus has been known since decade. Mycorrhizae could promote the growth of almost all species of plants. Biofertilizer product based on mycorrhizae fungus has been produced commercialization and easily found in the market. This study was aimed to understand the positive effect of mycorrhizae inoculation when it mixed with other microbes especially nitrogen fixing bacteria and growth hormone production bacteria. An experiment was set up at green house to run the activities of microbes inoculation on soybean plants. Soybean was mainly used for testing the potential of soil microbes since the target of the experiment is increasing the production of soybean seed and decreasing the used of chemical fertilizer. The result of this study showed that multi strains inoculation was better that single inoculation. Single mycorrhizae inoculation produced slightly higher number of pods. However when the mycorrhizae was combining with other potential microbes the number of pods produced by the plants even significantly higher than only single inoculation. Updating the quality of biofertilizer is needed by including the biodiversity of soil microbes to gain the promotion of green farming program.
