Popis: The response of second crop corn to nitrogen application was evaluated at different stages of development. The experiment was conducted on the São Carlos farm in Vilhena – Rondônia/Brazil. The factors under study included the splitting of N associated with the application of coated urea with NBPT (45-00-00) in top dressing. The control group (witness) showed the highest productivity among all treatments, with 7962 kg ha-1, followed by V3+V7 (7895 kg ha-1) and V4+V8 (7821 kg ha-1). The lowest productivity was 6630 kg ha-1 in V5+V9, indicating that the later the urea application in defining the productive potential of the crop (V4), the lower the yields achieved.
