Inadequate fertilization affects the production of quality seedlings, because they need a balancedbalance of essential nutrients, in the concentrations required to grow properly. With the above,it was proposed to determine the effect produced by fertilizers calcium triple superphosphate, ammoniumnitrate and potassium nitrate fertilizers on the variables number of leaves, plant height,plant diameter, root length and root biomass wet seedlings of Eucalyptus deglupta Blume (Myrtaceae).For this, three nutritional schemes were established of N, P, K and Ca (190-35-210-150 ppm)T1; (150-50-250-180ppm) T2; (140-55-300-200 ppm) T3 and a control without T4 solution. After 60days, the concentrations of N, P, K and Ca (190-35-210-150 ppm) determined greater growth in thenumber of leaves (22,3 leaves); plant height (157,26 mm); plant diameter (2,41 mm) and wet rootbiomass (6,6 g). However, the observations indicate that for the root length variable, the treatmentssupplied with concentrations of N, P, K and Ca, did not show significant differences in their means.
