ABSTRACT

Soybeans are a strategic food crop with a national demand level of 2.8 million tons/year and until now still depend on imports of up to 65%. This study aims to: (1) determine the effect of liquid organic fertilizer from tofu waste on the growth and yield of soybeans in ultisol planting media; (2) determine the effect of trichokompos on the growth and yield of soybeans in ultisol planting media; and (3) determine the effect of a combination of treatments on the growth and yield of soybeans in ultisol planting media. The study used a two-factor Randomized Block Design with three replications. The first factor was the provision of liquid organic fertilizer from tofu waste (T) consisting of: control (without liquid organic fertilizer from tofu waste) (T0), 100 mL/L/polybag (T1), 200 mL/L/polybag (T2), and 300 mL/L/polybag (T3). The second factor is the provision of trichocompost (K) fertilizer consisting of: control (without trichocompost fertilizer) (K0), 5 tons/ha = 25 g/polybag (K1), 10 tons/ha = 50 g/polybag (K2), and 15 tons/ha = 75 g/polybag (K3). The provision of tofu waste LOF can increase plant height, number of branches, number of filled pods, and weight of soybean pods. The best LOF tofu waste administration was obtained at a dose of 300 mL/L/polybag (T3). The provision of trichocompost fertilizer can increase plant height, number of branches, number of filled pods, and weight of soybean pods. The best trichocompost fertilizer administration was obtained at a dose of 75 g/polybag (K3). The interaction of tofu waste LOF and trichocompost fertilizer can increase the number of branches, number of filled pods, and weight of soybean pods. The best combination treatment for dry seed weight at T3K1 (300 mL LOF and 25 g trichocompost fertilizer).
