Resumo: | The aim of this work was to evaluate the seedling growth of Eucalyptus badjensis Beuzev. &amp; Welch in substrata prepared from different residues: pulp and paper mill wastes (organic sludge and cellulose mill liquid alkaline liquor), brewery malt and also goat manure. The experiment was carried out in the seedlings nursery of the Embrapa Florestas, in Colombo, Paraná. The organic sludge, cellulose mill liquid alkaline liquor and the brewer’s grain were previously composted with sawdust, and goat dung with pinus bark. A randomized blocks design with split-plot arrangement, with four replications was used. Plot treatments were the substrata and split-plot were base fertilization (with and without): 1) mixture of a commercial substratum prepared with composted pinus bark in a volume/volume relation - v/v - of 1/1 - standard of the experiment when base fertilization was applied; 2) composted brewery malt with sawdust in a relation v/v of 1/4; 3) composted organic sludge with sawdust (relation v/v of 1/1); 4) mixture oftreatment 3 with pinus bark (relation v/v of 1/1); 5) composted cellulose mill liquid alkaline waste with sawdust (relation v/v of 4/1); 6) composted cellulose mill liquid alkaline waste with sawdust (relation v/v of 3/2); 7) mixture of the productof treatment 6 with Pinus bark (relation v/v of 1/1); 8) composted goat dung with pinus bark. The results showed that substrata of treatments 2 and 8 can be used for the production of E. badjensis seedlings, with or without base fertilization, while treatment 4 can only be used with base fertilization. The growth of E. badjensis in the substratum of the standard treatment was not influenced by the lack of base fertilization.
