An experiment was conducted at the Instructional farm of IGKV, Raipur during kharif season of 2008 to evaluate the production potential of different varieties of cowpea under varying levels of phosphorus. Results revealed that all the growth parameters was influenced significantly due to varieties and levels of phosphorus. Cowpea variety UPC-626 resulted in taller plants with profuse branching coupled with maximum number of leaves and nodules plant-1 which in turn produced significantly maximum green (306.66 q ha-1) dry fodder (42.66 q ha-1) yields. However, variety UPC-629 was found to be superior in seed production (183.94 kg ha-1). Application of phosphorus @ 80 kg P2O5 ha-1 was found to improved vegetative growth of cowpea, consequently the yield of green (288.39 q ha-1) and dry fodder (27.00 q ha-1) quality of the produce was increased significantly as compared to lower level of phosphorus fertilization. However, seed yield of cowpea was enhanced only up to 60 kg P2O5 ha-1 followed by reduction in seed yield at 80 kg P2O5 ha-1. Interaction of variety and levels of phosphorus enabled the crop to increase seed and fodder yields significantly.
