Abstract

Three levels of P (0.0, 16.0 and 32.0 ppm), B (0.0, 2.0 and 4.0 ppm), Zn (0.0, 3.0 and 6.0 ppm) and two levels of lime (0.0 and 6.0 gr. CaCO3 + 2.5 gr. MgCO3) were applied to 8.0 kg of an orthox soil, originated from "Cerrado" area from Itirapina (SP, Brazil). A factorial experiment consisting of 3³ x 2 with two replications was conducted in a greenhouse at Piracicaba (SP), Brazil). Phosphorus and liming had a significant effect on growth and matter production by Eucalyptus. The boron levels (2.0 ppm and 4.0 ppm) interacted with lime, P and Zn application. The addition of 3.0 ppm and 6.0 ppm of zinc to the soil interacted negatively with B and P on the growth of the plants.
