Role of Phosphorus and Inoculation with Bradyrhizobium in Enhancing Soybean Production

Soybean (Glycine max L. Merril) is among the key oil seed crops worldwide, providing several benefits from human consumption to enhancement of soil productivity. In Uganda, legumes are cultivated on roughly 1.5 million ha, with soybean being produced a lower production area 150,000 ha compared beans (925,000 ha) and groundnuts (253,000 ha). terms achievable yield, emerges highest at 1.2 t·ha−1 as (0.5 t·ha−1) (0.7 t·ha−1). Despite smallest coverage area, crop’s feasible grain yield projected 4.6 under optimal environmental conditions. The major bottleneck decreasing fertility, mainly caused by low nitrogen (N) but also phosphorus (P) levels in soil. There high potential for supplying N atmosphere through biological fixation (BNF), natural process mediated symbiotic bacteria Bradyrhizobium japonicum, which requires optimum P effective increased yield. current work reviews present status highlights its ecological requirements, importance, constraints, proposes use inoculation application boost production.
