In a field experiment was conducted during the kharif 2015 at Agronomy field unit of College of Agriculture, University of Agricultural and Horticultural Sciences, Navile, Shivamogga to study the effect of different slow release nitrogenous fertilizers available status of nutrients in soil and their uptake by maize at different growth stages of maize. The experiment was laid out on sandy loam soil by adopting Randomised Complete Block Design. The treatments consisted three different coated urea products viz.,neem coated urea (NCU), pongamia oil coated urea (POCU) and castor oil coated urea (COCU) were applied either in single at sowing and in split application at 30 days after sowing. The results indicated that neem coated urea was recorded significantly increased nutrient availability and uptake by maize. Application of 100 % Rec. N through NCU as basal was recorded significantly higher availability of NPK and higher uptake of nutrients over other treatments.
