Cowpea (Fertilization)

The well nodulated cowpea crop can meet much of its nitrogen requirements and in most tropical soils cowpea nodulates well with indigenous Rhizobium. However, cowpea responds to nitrogen in soils with low contents of organic matter. Nitrogen application is recommended for soils containing less than 2% organic matter not later than 2 weeks after planting date. Phosphorus, although not required in large quantities is critical to cowpea yield. In order to achieve optimum yields a basal dressing of 200-300 kg/ha of compound "D" is recommended. A top dressing of about 100 kg of ammonium nitrate or 75 kg of urea per hectare may be necessary and can be applied if leaves turn yellow, an indication of nitrogen deficiency.
