Placement of applied N at surface and at the 5‐cm depth at the rates of 50, 100, and 200 kg/ha of urea and sulfur‐coated urea (SCU) were used to measure changes in grain yield and N uptake by corn ( Zea mays L.) grown during the wet season in Trinidad. SCU performed better than urea. Surface applied SCU was more efficient than when placed at 5 cm depth. Urea placed at 5 cm depth was more efficient in corn production than when applied on the surface.
