Effect of Boron Fertilizer and Double Inoculation of Rhizobium sp and Phosphate Solubilizing Bacteria on Soybean (Glycine Max L.) Growth and Production

Because of their high protein content, soybeans are a vital source of protein for human survival. By fertilizing with substances like biological fertilizers and micro fertilizers to meet the nutritional requirements of plants during growth, efforts can be made to increase the quality and quantity of soybean harvests.This research examines the effect of boron fertilizer and double inoculation doses, Rhizobium sp. and different Phosphate Solubilizing Bacteria (PSB) on soybean growth and production. A 3x4 factorial pattern with three replications and a completely randomized design (CRD) were used in this study. The first factor is the dosage of boron fertilizer (B) used, which has three treatment levels: B0 = 0 kg/ha (Control), B1 = (1 kg/ha), B2 (2 kg/ha), and B3 (3 kg/ha). The second factor is the double inoculation dose of PSB (R) and Rhizobium sp. with four treatment levels, namely R0 = control, R1 = 6 g/seed, and R2 = 12 g/seed. The findings demonstrated that the best pods, seed weight, and root nodules were produced by the double inoculation dose of Rhizobium sp. and PSB 12 g/seed. The production and growth of soybeans have not been impacted by boron fertilizer. On the other hand, the quantity of soybean seeds is impacted by the interaction of double inoculation doses of Rhizobium sp. and PSB with a dose of boron fertilizer.
