The Enterolobium contortisiliquum (Vell.) Morong. is a tree of Brazilian origin, occurring from north to south, from the family Leguminosea-Mimosoideae. The objective of this study was to evaluate the effect of different substrates on germination and seedling growth of tamboril. The treatments were: T1 - soil, T2 - soil + manure, T3 - soil + carbonized rice straw and T4 - soil + manure + carbonized rice straw. The evaluated variables included emergence percentage, emergence speed index, plant height, number of leaves, stem diameter, weight of the fresh and dry matter on the aerial parts and weight of fresh and dry root. The experimental design was completely randomized with four treatments and five replications of 20 seeds. The emergence and the emergence speed index had better performance in substrates soil +manure and soil + carbonized rice straw. The characteristics of the seedlings growh at 120 days after sowing has positively influenced by the presence of manure in the composition of the substrate.
