Resumo Inglês:

In producing forest seedlings, the use of residues may be an option to improve seedling quality. Thus, the objective of this study was to evaluate the initial growth and quality of Toona ciliata seedlings on different substrates. The experimental design was completely randomized with seven treatments consisting of commercial substrate (CS), vermicompost (VC), urban waste compost (UWC) and mixtures in proportions of 50% (CS + VC, CS + UWC and VC + UWC) and 33% (CS + UWC + VC), with twelve replications. The use of substrates composed of organic residues 120 days after sowing shows potential for producing Toona ciliata seedlings. The combination of substrate components provides higher seed growth and quality than unmixed substrates. Compositions of 50% UWC or 50% VC + 50% CS are efficient in growth and seed quality.
