Cowpea (Vigna unguiculata L.), as an important economic vegetable crop, is highly sensitive to nutrient supply conditions. Traditional fertilization methods often have problems such as excessive dosage, nutrient imbalance and environmental pollution. This study took the typical cowpea main production area as the research object, and compared and analyzed the effects of two fertilization methods on cowpea yield, root growth, leaf nutrient content, soil organic matter and pH changes. At the same time, the utilization efficiency of nitrogen, phosphorus and potassium fertilizers and the potential impact on the agricultural ecological environment of different fertilization methods were evaluated. The results showed that compared with the traditional fertilization method, soil testing and formula fertilization can significantly improve the yield and quality of cowpea, promote the development of root system and plant robustness, enhance the absorption capacity of nitrogen and other nutrients, and effectively improve soil fertility and structure. This study hopes to promote the green and efficient planting of cowpea and promote the sustainable development of regional agriculture.
