Abstract

The present study aimed to evaluate the influence of different materials in the emergency and growth of Enterolobium contortisiliquum seedlings. Distinct substrates were formulated using vermiculite, charcoal wastes, subsoil, organic compost and wood sawdust, consisting of 16 treatments. The variables emergency, speed index and average time of emergency, total height of the plant, length of the root, length of the stem, root collar diameter, number of nodules, root and stem dry mass, root volume, and the Dickson Quality Index, were analyzed during 120 days. Almost all the substrates provided satisfactory results, especially the treatments with 50% of vermiculite, 50% of organic compost and the treatment with 33% vermiculite, 33% charcoal wastes and 33% organic compost.
