Abstract: Field experiment was conducted to find out the influence of Urea, KCl, Zn placement and spray on growth of Cowpea crop. Crop during Kharif season 2017 under guava based agri-horti system. The experiment was laid out in simple RBD design and replicated thrice. The treatments were nine. Application of various levels of KCl, Zinc and Urea which significantly increased dry matter production/plant, plant height, number of branches/plant, number of trifoliate/plant, total nodule / plant. Foliar nutrient sprays viz., 2% urea, 2% KCL, 1.5% ZnSO4 Foliar spray treatment with the aqueous solution of nutrients was done to the 15 and 30 DAS of Cowpea crop. Significant increase was recorded in plant height, dry matter production, Maximum growth was recorded when spread with 2% urea spray followed by 2% KCl at flowering and 15 days later is the viable nutrient management package to the Cowpea for getting higher income through higher productivity.
