Abstract
This study aimed to find an effective combination of mycorrhiza, PGPR (Plant Growth Promoting Rhizobacteria), and inorganic fertilizers. Whereas the specific purpose was observed in effective mycorrhiza to increased chlorophyll content. This study used a completely randomized design (CRD) with three factors: the 1st factor is mycorrhiza application, the 2nd factor is PGPR and the 3rd factor is the application of nitrogen and phosphorus fertilizers. The data were analyzed with Analysis of Variance to determine the effect of the treatment being tried. Continued with the Least Significance Different test at a 95 % confidence level. The results indicated that the most effective application in increasing total chlorophyll content was (i) the ‟Commercial Mycorrhiza” without being combined with PGPR and fertilizer (TP.TR.MP:80 g mL–1). (ii) ‟Brawijaya Mycorrhiza” is combined with PGPR without fertilizer (TP.R.MB: 83 g mL–1). (iii) ‟Unida Mycorrhiza” without combined with PGPR and without fertilizer (TP.TR.MU: 80 g mL–1).
Highlights
This study aimed to find an effective combination of mycorrhiza, PGPR (Plant Growth Promoting Rhizobacteria), and inorganic fertilizers

Summary
This study aimed to find an effective combination of mycorrhiza, PGPR (Plant Growth Promoting Rhizobacteria), and inorganic fertilizers. The results indicated that the most effective application in increasing total chlorophyll content was (i) the ‟Commercial Mycorrhiza” without being combined with PGPR and fertilizer (TP.TR.MP: g mL–1). Mycorrhizal fungi can help plants absorb phosphorus and water absorption, while PGPR can provide nitrogen for black soybean plants. PGPR application can support the formation of mycorrhiza and can improve various functions adequately, such as Arturson's research inoculation with strains of the bacterium Paenibacillus brasilensis has been shown to increase the level of root colonization by mycorrhizal fungi and can absorb phosphorus elements so as to increase plant growth [6]. While the specific purpose of this research is to find mycorrhizae that are effective in nutrient absorption to increase chlorophyll content
