Four levels of fertilizer were tested (0, 2.0, 4.0 and 6.0 g dm–3) in three types of substrates: BIOCPI = Sewage sludge + Peach-palm bark (1:1 v:v); BIOCPII = Sewage sludge + Peach-palm bark (1:2 v:v) and BIOCPIII = Sewage sludge + Peach-palm bark (1:3 v:v). Plant height, stem diameter, dry matter (shoot and root), height/diameter ratio, Dickson quality index and N, P, K, Ca, Mg, and S contents in the shoot were measured. The use of the substrates BIOCPII and BIOCPIII proved to be viable for the production of Brazilian Peppertree seedlings. Doses above 4.0 gdm–3 of granular fertilizer are recommended for better results. Keywords: macronutrients, nurseries, sewage sludge, substrate, Brazilian Peppertree.
