Yes, location (soil type and water content) will affect Nitrogen accumulation by symbiotic bacteria of legumes, and low PK content will significantly reduce yield. Commercial inoculants can improve cowpea growth, 45 kg/ha K2O application without P was recommended for sustainable vegetable cowpea production in an acidic soil of Southeastern Nigeria, especially when the soil has high available P (above the critical P level of 7 mg/kg recommended for cowpea production).
