Abstract
Soybean (Glycine max L. Merril) is a major food commodity with high demand in Indonesia, both for consumption and industrial purposes. Efforts to increase soybean productivity require optimal fertilization, including a combination of Bio P2000Z and NPK fertilizer. This study aimed to analyze the effects of Bio P2000Z and NPK fertilizers on the growth and yield of the Ratu Serang soybean variety. The research was conducted from January to May 2025 at the Gunadarma University Technopark field in Cianjur, using a Factorial Randomized Complete Block Design (RCBD) with two factors: Bio P2000Z concentration (0, 5, 10%) and NPK fertilizer dosage (0, 1, 3 g/plant). There were nine treatment combinations with four replications, resulting in a total of 36 experimental units. The observed parameters included flowering ageand yield (harvest age, number of pods per plant, fresh biomass weight, and dry biomass weight). Data were analyzed using ANOVA at a 5% significance level followed by the Duncan Multiple Range Test (DMRT) post-hoc test. The results showed that both Bio P2000Z and NPK fertilizers had a significant effect on the growth and yield of the Ratu Serang soybean variety.
