Walp) locally known as Chaula or Chowlee., is an important pulse crop of India. With a view to find out a suitable variety and optimum spacing and dose of phosphorus for economical and quality seed production of cowpea per unit area and time, this investigation was carried out under irrigated conditions in summer. A field trial was laid out at the seed technology for S. A. U., Sardarkrishinagar during summer 1983. Twenty four treatments involving combinations of two varieties (Gujarat cowpea-1 and Gujarat cowpea-2), three spacings (30, 45 and 60cm) and four phosphorus levels (0, 20, 40 and 60 kg/ha) were laid out in a factorial Randomized Block Design with three replications.enAGRONOMY, AGRICULTUREA STUDYThesis
