Abstract: Phosphorus (P) is one of the most essential macronutrients for plants, contributing to critical physiological and biochemical functions. In common bean (Phaseolus vulgaris L.), phosphorus plays a pivotal role in growth, nodulation, nitrogen fixation, photosynthesis, and reproductive development. However, its availability in the soil is often limited, especially in tropical and subtropical regions, where phosphorus fixation and leaching are common. This review provides a comprehensive analysis of phosphorus’s role in common bean growth, focusing on its impact on root architecture, nutrient uptake, and yield parameters. Practical strategies for enhancing phosphorus efficiency and soil management are also discussed.
