Phosphorus (P) is a critical macronutrient for soybean (Glycine max L.) growth and productivity. This study investigates the effects of varying phosphorus fertilizer rates on soybean growth, development, and yield parameters. Field experiments were conducted to evaluate plant height, leaf area index, pod number, seed yield, and phosphorus use efficiency (PUE). Results indicate a significant improvement in growth and yield metrics at optimal phosphorus application rates, while excessive or deficient rates hindered performance. The study highlights the importance of phosphorus optimization in enhancing soybean productivity and provides practical recommendations for sustainable phosphorus management.
