SUMMARY
Given the occurrence of a vast amount of degraded areas in Brazil, recovery projects have been necessary. In order to propose a feasible project, we must be concerned about the production of seedlings, preferably native ones, using low-cost inputs. In this research, we aimed to evaluate the seedlings growth of two forest species (Eugenia uniflora and E. involucrate) in different base saturation of a substrate. To this, we tested different dosages of dolomitic lime applied to a substrate composed of soil and sand in a 70/30 ratio. By varying the base saturation of substrate at 40%, 45%, 50%, 55% and 60%, five treatments were tested in a completely randomized design with five repetitions of three seedlings per treatment. We verified that in a mixed substrate of soil and sand the base saturation equal to 45% was the best one to improve the height growth of E. uniflora and E. involucrata seedlings during one year of evaluation. There was no significant difference among treatments in relation to the variable collar diameter and height/collar diameter ratio for E. involucrata
