O objetivo deste trabalho foi avaliar substratos alternativos para o cultivo da bromélia Aechmea fasciata (Lindley) Baker, para substituir com eficiência as misturas formuladas com o xaxim Dicksonia sellowiana (Presl.) Hook. Foram testados os substratos: casca de Pinus, casca de Eucalyptus, coxim, fibra de coco e xaxim, misturados com turfa e perlita, nas proporções 2:7:1, 5:4:1 e 8:1:1. O experimento foi realizado em condições de estufa com cobertura de polietileno, sombreada com tela a 70%. As bromélias foram cultivadas durante 435 dias, até o início do florescimento - estádio de comercialização. As variáveis analisadas foram as massas de matéria seca de: folhas, raiz, inflorescência, escapo floral e caule; além da massa de matéria seca total e a qualidade comercial. Os substratos formulados com xaxim ou casca de Pinus, nas proporções 2:7:1, 5:4:1 e 8:1:1, e com casca de Eucalyptus, fibra de coco ou coxim, na proporção 2:7:1, foram as misturas que apresentaram os melhores resultados. Os substratos formulados com casca de Eucalyptus, fibra de coco ou coxim, com 10% de turfa e 10% de perlita, na proporção 8:1:1, apresentaram os piores resultados. The objective of this study was to evaluate alternative substrates for the cultivation of the bromeliad Aechmea fasciata (Lindley) Baker, to substitute the formulated mixtures with fern tree fiber from Dicksonia sellowiana (Presl.) Hook. Tested substrates were: Pinus bark, Eucalyptus bark, coxim (made of coconut fiber), coir or fern tree fiber, mixed with peat and perlite, in the proportions 2:7:1, 5:4:1 and 8:1:1. The experiment was conducted in a greenhouse covered with polyethylene and shaded with shade cloth 70%. The bromeliads were cultivated during 435 days, until the beginning of the flowering, when they were suitable for commercialization. The evaluated parameters were dry masses of leaf, root, inflorescence, floral scape, and stem, besides total dry mass and the commercial quality. The substrates formulated with fern tree fiber or Pinus bark, in the proportions 2:7:1, 5:4:1 and 8:1:1, and with Eucalyptus bark, coir or coxim, in the proportion 2:7:1, showed the best results. The substrates formulated with Eucalyptus bark, coir or coxim in the proportion 8:1:1 presented the poorest results
