Studies on Nodulation and Yield of Cowpea (Vigna unguiculata (L) Walp)



Thirty-five (35) cultivars of cowpea (Vigna unguiculata (L.) Walp.). were used
in pot and field experiments to investigate nodulation pattern wih plant biomass and the relationship between yield and yield attributes. Nodule initiation was observed within 5 days after emergence in all the cowpea varieties
