A field experiment was conducted using maize as a test crop at Agronomy field unit of College of Agriculture, University of Agricultural and Horticultural Sciences (UAHS), Navile, Shivamogga during Kharif 2015 to study the effect of different oil coated urea fertilizers on nutrient content and uptake in maize. The experiment consists ten treatments laid out in three replications using three different coated urea products viz., neem coated urea, pongamia oil coated and castor oil coated urea. The results indicated that neem coated urea significantly increased nutrient availability and uptake by maize. Application of 100 % Rec. N through NCU as basal was recorded significantly higher NPK content in rainfed maize. Significantly higher nutrient uptake was observed in the treatment which received application of 100 % Rec. N through NCU as basal over other treatments.
