ABSTRACT
Cultivation of soybean plants on Ultisol has low available-P constraints. One of the efforts to increase available-P is by fertilizing. This study aims to obtain the best combination of doses of N, P, K fertilizers with the best number of applications of phosphate solubilizing bacterial biofertilizers for growth and results in reducing inorganic use in soybean plants in Ultisol soil. The study used a non-factorial Completely Randomized Design (CRD). The treatments used were: PI: doses of N, P, K 100% + without the application of Phosphate solubilizing bacteria PSB, P2: doses of N, P, K 75% + 3 times the application of Phosphate solubilizing bacteria (PSB), P3: doses of N, P, K 75% + 4 times the application of Phosphate solubilizing bacteria (PSB) biofertilizers, P4: 50% N, P, K + 3 times the application of Phosphate solubilizing bacteria (PSB) biofertilizers, P5: doses of N, P, K 50% + 4 times the application of Phosphate solubilizing bacteria (PSB) biofertilizers. Parameters observed were plant height, percentage of effective root nodules, flowering age, number of productive branches, harvesting age, number of pods per plant, dry weight of 100 seeds and harvest index. The results showed that the application of combination doses of N, P, K fertilizers and Phosphate solubilizing bacteria could reduce the use of N, P, K fertilizers for the growth and yield of soybean plants. The best dose of 75% N, P, K application + 4 times the application of Phosphate solubilizing bacteria (PSB) biofertilizers speeds up harvesting, increases the weight of 100 seed, and increases the weight of the planted seeds.
Keywords: Soybean plants, N, P, K fertilizers, Phosphate solubilizing bacteria (PSB) biofertilizers.
