M. de  aShading and slow release fertilizer effects on the growth characteristics of assai seedlings (Euterpe oleracea).h[electronic resource]  c2019  aThe objective of this work was to evaluate the initial growth of assai seedlings (Euterpe oleraceae) in response to shading and slow release fertilizer. The experiment was conducted at Embrapa Acre in a randomized block design using a 4 × 5 factorial scheme with three replicates and 10 plants per plot. The treatments consisted of four shade environments (20%, 30%, 50% and 75%) and five levels of slow release fertilizer (0.0, 2.5, 5.0, 7.5 and 10.0 kg m-3). The following characteristics were evaluated: plant height, number of leaves, stem diameter, leaf dry mass, stem dry mass, root dry mass, total dry mass, and seedlings quality index. The growth of assai seedlings was influenced by shade environment conditions and slow release fertilizer. Shade environment with 30% or 50% and a dose of 8 kg m?3 resulted in better quality seedlings.  aAgronomic traits  aPlant growth  aSeedling production  aShade  aSlow-release fertilizers  aAçaí  aCaracterísticas Agronômicas  aEuterpe Oleracea  aMuda  aProdução  aSombreamento  aAcre  aAmazonia Occidental  aAmazônia Ocidental  aCrecimiento de planta  aEmbrapa Acre  aFertilizante de liberação lenta  aFertilizantes de acción retardada  aProducción de plántulas  aRio Branco (AC)  aSombra  aWestern Amazon1 aANDRADE NETO, R. de C.1 aOLIVEIRA, J.
