Poultry manure application to crop land is a widely used practice in the Delmarva (Delaware, Maryland, Virginia) region. This increases phosphorus (P) in the riparian environment causing degradation of aquatic systems and serious ecological side effects. We evaluated five genotypes of cowpea to explore their potential for the removal of P from soils enriched poultry manure. The field experiments were conducted during two growing seasons at the Experimental Station, University of Maryland Eastern Shore, Princess Anne, Maryland at a site which had a history of heavy poultry manure applications during the last ten years. Experiments were arranged in a randomized complete block design with four replications. Harvesting of the cowpea genotypes was done at pod formation stages, and the plant samples were oven dried at 70º C for three days. The dry samples were ground and analyzed for P content. Results showed that cowpea genotypes Champion and White Acres extracted significantly higher amounts of P in both growing seasons compared with the other cowpea genotypes. These two genotypes were also found to have a higher potential for P uptake from poultry manure enriched soil. This innovative approach of using cowpea genotypes can play an important role in improving nutrient management and enhancing agrosustainability. Since both of these cowpea genotypes are spreading types, they could be used as a fodder for livestock.
