Anthurium (Anthurium x Cultorum) is one of most important cut flower grown worldwide, and the evolution of its culture has evolved towards the use of alternative substrates. The objective of this research was to evaluate the vegetative and productive performance of the anthurium cv. Arizona grown in economic, available and ecologically sustainable substrates, under tropical conditions. Using a completely randomized design with four repetitions and 16-plant plots, the following six treatments were evaluated: phenolic resin (RF); mix of 2/3 sugar cane bagasse (BC) + 1/3 rice hulls (CA); mix of 1/2 BC + 1/2 CA; mix of 2/3 coir dust (AC) + 1/3 CA; mix of 1/2 AC + 1/2 CA; and coconut shell in pieces (CT). The RF and CT were the most stable substrates. The least established plants, shoots and leaves occurred in CT attributed to the hydrophobic condition of the fibers. As the proportion of AC increased the plant growth tended to decreased as the probable result of its lower water holding capacity. In general, the substrates containing AC yielded better results than those with BC regarding stability, plant growth and flower production.
