Eucalyptus camaldulensis is a species of eucalyptus with potential for establishment planted forests in the savannah area Roraima. Little known about appropriate management E. conditions Roraima, and this reason, an experiment was conducted to evaluate effects nitrogen (N), phosphorus (P) potassium (K) production essential oil species. The ½ 43 fractional factorial design, that evaluated four doses N (0, 50, 100, 200 kg ha-1), P 30, 60, 120 ha-1) K ha-1). One year after planting, yield determined fresh leaves, extraction performed by method hydrodistillation Clevenger type system. changed mainly due fertilization, increasing from 0.43 0.62% as it increased P. These values were within range 0.3 2.8% literature leaves . highest observed dose ha-1 phosphorus.
