| Summary: | This study aimed to evaluate the effect N, P and K on the growth of young (19 month-old) Pinus
taeda. 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 Pinus taeda plants, with a maximum
cylindric volume achieved at 64 and 87 kg ha-1 doses of P2O5 and K2O respectively. |
