This research work had as objective to evaluate the effect of different substrates on emergence and seedlings development of Erythrina velutina Willd. The experiment was carried out at the greenhouse of the Laboratory of Vegetable Ecology in the Center of Agrarian Sciences - Federal University of Paraíba. The substrates evaluated were washed sand; washed sand + vermiculite in the proportions of 1:1, 3:1 and 1:3; vegetable earth, vegetable earth + washed sand in the proportions of 1:1, 3:1 and 1:3, vegetable earth + vermiculite in the proportions of 1:1, 3:1 and 1:3, vermiculite, bioclone®, bioplant® and plugmix®. The experimental design was completely randomized with fifteen treatments (substrates) and four replications of 25 seeds. The effect was evaluated through percent of emergence, first count, emergence velocity index, medium time and relative frequency of emergency, length and dry mass of the root and it leaves aerial of the seedling. The substrates sand and vermiculite had the best results and are recommended for conduction of tests of emergency of mulungu seedlings.
