When associated an adequate shading and nutrition the seedlings to reach characteristics that allow them to
survive in the field and increase production. Thus, this work aimed to evaluate the production of Oenocarpus
bataua seedlings in response to different shade environments and controlled-release fertilizer doses. The
study was carried out from at the Embrapa nursery located in the municipality of Rio Branco, Acre state. The
experimental design was complete randomized blocks with three replications and six plants per plot. The
treatments were distributed according to a 4 x 5 factorial scheme, i.e., four shade environments (20%, 30%, 50%
and 75%) and five CRF doses (0.0, 1.5, 3.0, 4.5 and 6.0 kg m–3) mixed with the substrate. Biometric, biomass and
quality variables were evaluated at 305 days after transplanting. The ANOVA was applied for the qualitative
factor and regression analysis was performed for the quantitative factor, both at 5% probability. The treatments
were grouped by analyzing canonical variables, a multivariate statistical and realized the Pearson’s correlation
between variables was determined through correlation networks. The shading environment and the controlledrelease
fertilizer positively influenced the growth and quality of Oenocarpus bataua seedlings. The seedlings of
Oenocarpus bataua have better biometric characteristics produced in a nursery with 50% shading. Oenocarpus
bataua seedlings show better quality when 3.88 kg m-3 of controlled release fertilizer are used.
