The treatments were six nitrogen rates of urea corresponding at 0; 9; 18; 27; 36; e 45 g of N*plant-1. The experimental design was a randomized blocks with six treatments and five repetitions with four plants per fragment. The characteristics evaluated were: height of tree, Diameter at Breast Height (DBH at 1,30 m from soil) and Diameter at Lap Height (DLH at 0,05 m from soil) The evaluation system to collect measures was in a permanent plot system. There were no statisticals differences among the treatments at 5% of significance.
