| Summary: | ABSTRACT The aim of this study was to evaluate the effect of sources and rates of organic waste and their interaction on the growth of Leucaena leucocephala (Lam.) de Wit, in the Southeast region of Piauí State. The treatments consisted of two sources (Copernicia prunifera (Mill.) H.E. palm residue and plant compound) and six organic waste rates. The study was conducted in the period of March-June 2011 and the following parameters were evaluated: stem diameter, height, number of leaves, shoot dry weight, root dry weight, total dry matter, root volume, shoot dry weight/root dry weight ratio, height/stem diameter ratio and the Dickson Quality Index. The Copernicia prunifera (Mill.) H.E. palm residue and plant compound showed a great potential to be used in the manufacture of substrates for the production of seedlings Leucaena leucocephala (Lam.) de Wit, since their initial development was influenced by the sources and proportions of these organic residues and by the interaction between these treatments. The substrate containing 50% of plant compound produced better quality of plants of Leucaena leucocephala (Lam.) de Wit in their initial development stage. |
