ABSTRACT
The objectives of this study were to evaluate substrates produced from the peach-palm agroindustry
waste and sewage sludge as a source of nutrients for the production of Brazilian Peppertree
seedlings (Schinus terebinthifolius Raddi), and to compare the performance of these substrates
under various levels of slow release fertilizer for this species. 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.
