The study looked at how different fertilizer levels and planting densities affect the yield and traits of vegetable soybeans. They used a specific soybean variety in a field experiment. The results showed that the highest yield was achieved with a fertilizer level of PU50%+PCU50% and a planting density of 3.0×105 plants·ha-1, reaching 9,045.11 kg·ha-1. Plant height and effective pods per plant were greatly influenced by these factors, while branches, node number, and 100-fresh grain weight were less affected.
