Aplikasi Bahan Organik Tandan Kosong Kelapa Sawit Dengan Mikrob Selulolitik Dan Pupuk N, P, K Pada Tanaman Kedelai (Glycine Max (L.) Merrill)
ABSTRACT
Soybean (Glycine max (L.) Merr.) is a legume crop. Soybean productivity continues to decline, one of the reasons being the declining level of soil fertility. Efforts to increase the productivity of soybean plants by compensating the application of organic matter and inorganic fertilizers from empty oil palm fruit bunches with cellulolytic microbes and N, P, K fertilizers. This research was aims to determine the interaction of OPEFB + cellulolytic microbes and fertilizers N, P, K and single factors respectively and to obtain the best combination of treatments for soybean plants. The research was conducted experimentally with a completely randomized design (CRD). The first factor consisted of 3 levels, without OPEFB + cellulolytic microbes, OPEFB + cellulolytic microbes directly and composted OPEFB + cellulolytic microbes. The second factor consisted of 3 levels, namely 100%, 75%, 50% N,P,K fertilizer. Parameters observed were plant height, percentage of root nodules, weight root and header, flowering age, harvest age, productive branches, number of pods per plant, number of fruitful pods, weight of 100 seeds, weight of seeds plant and harvest index. The results showed that there was an interaction between OPEFB and cellulolytic microbes composted with 100% N,P,K on the parameters of the number of productive branches and the weight of 100 soybean plant seeds. The single factor of OPEFB with cellulolytic microbes and N,P,K fertilizers affected all parameters except flowering age, harvest age, and harvest index. The best combination is OPEFB with composted cellulolytic microbes and 100% N,P,K fertilizer.
Keywords : Soybean, OPEFB, Celulolytic microbes, N,P,K fertilizer.
