Resumo: Euterpe oleracea Mart. known popularly by açaí, influences and moves great markets in the Amazon region, mainly by the extraction of the pulp and palmetto. Therefore, the aimed of this study was to evaluate the influence of different types of substrates on the production, development, and quality of Euterpe oleracea Mart. seedlings popularly known as açaí. The experiment was conducted in the nursery of UFT, with randomized block design, with 7 treatments and 4 replicates, being 7 plants per replicate. The substrates used were: T1-Bioplant commercial substrate (100), T2-Bovine Manure + Carbonized rice husk (50:50), T3-Bovine Manure + sand (50:50), T4-Bovine Manure + sand: T5-Commercial substrate + Carbonized rice husk (25:75), T6-Commercial Substrate + Bovine Manure (25:75) and T7-Sand + Bovine Manure (25:75). The evaluations were done at 60, 90 and 120 days. The parameters evaluated were: height (H; cm), collection diameter (DC; mm), height/diameter ratio (H/DC), dry mass of the aerial part (MSPA; g plant-1), root dry mass (MSR; g plant-1), total dry mass (MST), relation between the aerial part dry mass and root dry mass (RMSPAR; g plant-1) and Dickson quality index (IQD). At 120 days, T6 presented better results in the parameters DC (6,62 mm) and H (30,16 mm). The T5 obtained better results for MSR (4,51 g) and IQD (1,41). The MSPA parameter was better in T1 (4,77 g), and T7 had better results in MST (9,06 g). Therefore, the treatments with bovine manure in its composition, in the proportions of 50% of Bovine Manure + 50% of Sand (T3), 25% of Sand + 75% of Bovine Manure (T7) and 25% of Bioplant Commercial Substrate + 75% of Bovine Manure (T6), provided the best growth in height and collection diameter, and increased dry mass production in Euterpe oleracea Mart seedlings.
