“…However, the N used by plants is only 30-50%, while P is 10-45% [18]. Ochrobactrum can fix N, dissolve P, and dissolve K [19,20]. Therefore, using BioF improves plant height and the leaf number of soybeans.…”

In the development of biofertilizers, it is necessary to carry out field tests to determine their effectiveness. This objective research is to know the ability of Ochrobactrum sp., Alcaligenes sp., and Bacillus sp. consortium on responses of soybean, carried out on Inceptisols Bogor, West Java. The research consists of seven treatments they control, a recommended dose of NPK, and five combinations of the microbial consortium with various dosages of NPK. The Urea, SP36, and KCl recommended dose measured by the upland soil test kit is 50, 100, and 100 kg ha−1. The research showed that NPK50% and NPK75% combined with microbial consortium as biofertilizer give soybean yield of 2.89 t ha−1 and 2.93 t ha−1, while the recommended NPK (NPK100%) yielded a soybean of 2.82 t ha−1. Biofertilizers can reduce the dose of NPK used by as much as 50%, equivalent to Urea 25 kg ha−1, 50 kg ha−1 SP36, and 50 kg ha−1 KCl, increase soybean yield by 13-21%, and improve relative agronomic effectiveness (RAE) value by 143-173%. Biofertilizer utilization is a promising strategy for inorganic fertilizers efficiency, increasing soybean yield in Inceptisols soil, and being environmentally friendly.
