<br/><br/> <br/><br/>ABSTRACT<br/><br/>The objectives of this study were to evaluate substrates produced from the peach-palm agroindustry<br/>waste and sewage sludge as a source of nutrients for the production of Brazilian Peppertree<br/>seedlings (Schinus terebinthifolius Raddi), and to compare the performance of these substrates<br/>under various levels of slow release fertilizer for this species. Four levels of fertilizer were tested<br/>(0, 2.0, 4.0 and 6.0 g dm–3) in three types of substrates: BIOCPI = Sewage sludge + Peach-palm<br/>bark (1:1 v:v); BIOCPII = Sewage sludge + Peach-palm bark (1:2 v:v) and BIOCPIII = Sewage<br/>sludge + Peach-palm bark (1:3 v:v). Plant height, stem diameter, dry matter (shoot and root),<br/>height/diameter ratio, Dickson quality index and N, P, K, Ca, Mg, and S contents in the shoot<br/>were measured. The use of the substrates BIOCPII and BIOCPIII proved to be viable for the<br/>production of Brazilian Peppertree seedlings. Doses above 4.0 gdm–3 of granular fertilizer are<br/>recommended for better results.<br/><br/>Keywords: macronutrients, nurseries, sewage sludge, substrate, Brazilian Peppertree.
