ABSTRACT

One effort to increase domestic soybean production and support the national food self-sufficiency program is to optimize the use of Inceptisol soil with infertile land characteristics. Regarding the potential use of Inceptisols soil, plant nutrient needs can be met by fertilizing, one of which is using organic vermicompost fertilizer. Vermicompost is compost made from the results of raising worms in compost. This research aims to determine the effect of applying vermicompost to increase soybean growth and yield as well as organic C content in Inceptisol soil. The research was carried out in the experimental garden of the Faculty of Agriculture, Islamic University of North Sumatra, Medan, North Sumatra using a Non-Factory Randomized Block Design with three replications with vermicompost doses as treatment, namely 0 t/ha (V0), 5 t/ha (V1), 10 t /ha (V2), and 15 t/ha (V3). The results showed that the application of 15 t/ha of vermicompost was able to increase the height of soybean plants by 16.70%, the number of productive branches by 20.75%, the number of pods per plant by 36.10%, the weight of the pods per plot by 33.17%, the weight of dry beans per plant plot. soybeans amounted to 24.08$, and soil organic C content amounted to 60.87%.
