This study aimed to determine the effect of the application of humic acid and Vesicular Arbuscular mycorrhiza (VAM) on the growth and production of soybean plants (Glycine max (L.) Merril) An experiment of a two-factor factorial design with randomized block design (RBD) took humic acid as the first factor consists of 3 levels: 0% (v/v), 10% (v/v), and 15% (v/v); VAM as the second factor consisting of 3 levels: 0 g, 6 g, and 12 g. Results showed that the application of humic acid did not have a significant effect on the growth component and some production component, yet it had a significant effect on the number of leaves 70 dap. Treatment of Vesicular Arbuscular Mycorrhizae (VAM) application did not have a substantial impact on the growth component and some production components. Likewise, there was no interaction between the treatment of humic acid application and VAM on growth components and some components of soybean production. Humic acid with a concentration of 10% (v/v) showed the best results on parameters of plant height, number of leaves, number of branches, flowering age, and root volume, while application of 6 g VAM gave the best results for plant height, flowering age, seed weight, and seed production per polybag.
