Symbiotic N2 fixation in 30 field-grown cowpea (Vigna unguiculata L. Walp.) genotypes in the Upper West Region of Ghana measured using 15N natural abundance
Abstract In this study, 30 cowpea genotypes were assessed for symbiotic N2 fixation in 2005, and 15 of them were reevaluated in 2006 using the 15N natural abundance technique. Shoot dry matter yield of cowpea genotypes increased significantly in cvs. Vuli-1, Glenda, IT93K-2045- 29, IT90K-59, Omondaw...
