| Summary: | <p>This study aimed to evaluate the effect N, P and K on the growth of young (19 month-old) <em>Pinus taeda</em>. The experiment took place near Cambará do Sul county, with UTM coordinates of 562125 E and 6777386 N. The statistical methodology was the confounding technique, for three factors, with four levels, totalizing 64 treatments, allocated in four blocks. The following variables were measured: total height, crown height, steam diameter and crown diameter. The results pointed out a significant linear quadratic effect for P, indicating that P fertilization is essential on the initial development of <em>Pinus taeda</em> plants, with a maximum cylindric volume achieved at 64 and 87 kg ha<sup>-1</sup> doses of P<sub>2</sub>O<sub>5</sub> and K<sub>2</sub>O respectively.</p> |
