Abstract
The aim of this study was to evaluate the growth of seedlings of Senna alata using different combinations of residues, which are: sewage sludge, carbonized rice husk, straw coffee in natura and commercial substrate. The experiment was conducted in the Nursery Center for Agricultural Sciences, Federal University of Espirito Santo, and mounted in a completely randomized design. When the seedlings reached five months growth the following parameters were measured: stem diameter, plant height, ratio between plant height and stem diameter, shoot dry mass, dry mass of root system, total dry mass, ratio of dry mass shoot/root dry mass, ratio of root dry mass/dry mass of shoots and Dickson quality index (IQD). It was found that for the production of seedlings S. alata recommend the use of 80% of sewage sludge mixed with 20% coconut fiber.
