This study was carried out aiming to fit a volumetric model and a growth function, as well to compare
the growth of teak (Tectona grandis) in a stand located at Iracema (RR) with the growth of teak stands located at different areas in Brazil and Central America. To fit volumetric models 122 sample-trees were used and to fit a growth function to estimate DBH, medium and dominant height, and total volume without bark 18 sampletrees were used. The Chapman-Richards function was used and the data were obtained by stem analysis. The Schumacher-Hall model was selected to estimate total volume with bark of Tectona grandis trees. Chapman-Richards is a suitable function for determination of the growth curves for DBH, medium height, dominant height and total volume without bark. Comparison among dominant height growth curves on different sites indicated that the stand located in Roraima did not present good performance probably due to low soil fertility levels.
