Euterpe oleracea Mart. is a native species from the Amazon, popularly known as açaí touceira, which has many applications, being important from an economic point of view. Due to the growth of the açaí market, there was also an increase in interest in the production of quality seedlings to meet this demand. Thus, the objective was to evaluate the use of alternative substrates in the development of açaí stump seedlings. The experiment was carried out in the forest nursery at Instituto Federal de Rondônia, Campus Ji-Paraná with 50% shading, from May to November 2018, with a completely randomized design with 5 treatments and 13 replications. The alternative substrates used were: T1: commercial substrate; T2 – soil + sand (1:1); T3 – soil + sand + cattle manure (1:1:1); T4 – soil + sand + sheep manure (1:1:1); T5 – soil + sand + chicken litter (1:1:0.5). The biometric parameters evaluated were: plant height, stem diameter, root length, dry mass weight and Dickson Quality Index (DQI). It was possible to verify that the substrate formulated with chicken manure was the appropriate substrate for the production of açaí seedlings.
