Abstract

Abstract

This reserach aimed to evaluate different doses of slow-release fertilizer (FLL) in  Schinus terebinthifolius and Sebastiania commersoniana seedlings development. The study was conducted in Vale do Itajai (SC), between March and December 2009, in a nursery in the city of Rio do Sul, with seeds from the region. The experimental design was completely randomized with 6 treatments in 4 replications, with 40 plants as experimental unit. The treatments were: T1-0 kg (control), T2-2 kg, T3- 4kg-, T4-6 kg; T5-8kg; and T6-10 kg per m³ FLL substrate base. After 189 (aroeira) and 245 (branquilho) days of sowing, the variables analyzed were total height, diameter, shoot dry biomass, root dry weight, total biomass and maximum dose of technical efficiency. The seedlings of aroeira and branquilho had better growth with the dose of 10 kg per cubic meter of FLL standard substrate and 6 kg per m3 of FLL, respectively. Both plants responded significantly to the use of slow release fertilizer, with the following maximum doses of technical efficiency 9.48 (aroeira) and 5.54 kg.m-3 (branquilho) of Basacote 6M.

Keywords: Sebastiana; red aroeira; fertilization; seedling production; quality forest seedlings.
