The aim of this study was to evaluate the effect of different substrates and luminosity in the early growth of Enterolobium contortisiliquum (Vell.) Morong. seedlings. It was used completely randomized design in factorial 5 x 2 (five substrates and two environments) with four replications of five plants in each plot. The substrates were: Commercial substrate (S1); soil (S2); sand (S3); soil + cattle manure (2:1 v/v) (S4) and sand + cattle manure (2:1 v/v) (S5). The environments were in full sun and with 50% of luminosity. The characteristics evaluated after 6 months in development were: Shoot lenght (CPA); roots lenght (CR); stem diameter (DC); leaf number (NF); dry matter of shoot (MSA); dry matter of roots (MSR); relationship between shoot and root dry matter and index quality Dickson (IQD). E. contortisiliquum seedlings with higher quality can be produced, in full sun or with 50% of luminosity, in substrates composed of soil and cattle manure or sand and cattle manure.
