The objective of this work was to evaluate the potential of the processed coconut fiber (coconut powder) and composted pine bark, isolated and in combination, in promoting the growth of umbuzeiro seedlings. This work was conducted in a greenhouse in a completely randomized block experimental design, with five treatments and four replications. The treatments consisted of the following formulations, in volumetric proportions: 100% pine bark (CP); 75% CP + 25% coconut powder (PC); 50% CP + 50% CP; 25% CP + 75% CP and; 100% PC). The coconut powder substrates or the formulation containing 75% coconut powder + 25% composted pine bark provided Imbu seedlings with higher vegetative quality. The lower density, higher total porosity and higher percentage of available water were the physical characteristics of the substrates that most influenced the growth of Imbu seedlings.
