Effectiveness of Mycorrhiza, Plant Growth Promoting Rhizobacteria and Inorganic Fertilizer on Chlorophyll Content in Glycine max (L.) cv. Detam-4 Prida

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).
