Background and Objective: Soybean is one of the main food commodities in Indonesia with high protein content. The need for soybeans is increasing in line with increasing public awareness of high protein foods, while soybean production in Indonesia is still very low. This study aims to analyze the growth and yield of two soybean varieties to increase the availability of phosphorus nutrients with the application of Arbuscular mycorrhizae. Materials and Methods: The experiment was designed in the form of a Split-Split Plot Design. As the main plot is the treatment of varieties consisting of two types, namely: Anjasmoro and Gema varieties. As a subplot is a mycorrhizal application consisting of two levels, namely without the application and mycorrhizal application. As sub-sub plots are phosphate fertilizers consisting of three levels, namely 50, 100 and 150 kg SP–36 ha1. Of the three factors obtained 12 treatment combinations. Results: The results showed that the growth of soybean plants was influenced by the variety used, and the interaction between phosphate fertilization and mycorrhizal application. In the pod weight parameters showed that the use of Anjasmoro varieties with mycorrhiza application and fertilization of 100 kg SP–36 ha1 obtained pod weight. Conclusion: The results showed that the selection of soybean varieties determines the level of production obtained. The study also discovered that the effectiveness of mycorrhizae in increasing the availability of phosphorus nutrients was obtained in fertilizing low doses of phosphorus.
