摘要：

This study aimed to evaluate the effects of different dosages of nitrogen (N) about the initial growth of 'parica' (Schizolobium amazonicum Huber ex. Ducke) seedlings. The experiment was conducted in a greenhouse and the seedlings cultivated in plastic bags filled with 5.0 kg of Oxisol, arranged in a completely randomized design with five treatments and ten repetitions. The nitrogen tests doses were 0, 40, 80, 120, 160 kg ha(-1). The heights, stem diameter, fresh aerial matter, root and total and height/diameter stem, were evaluated at 45 days post-transplant. All variables responses in a quadratic way to N applied doses. Until 45 days post-transplant, it was indicated the dose of 84.66 kg ha(-1) of N to obtain seedlings with greater height and 71 kg ha(-1) of N seedlings with a larger diameter.
