Today there is still a search for substrates economical, easy to use, available in large quantities and good characteristics for the production of seedlings, so are many substrates available. Thus, an experiment was conducted using different substrates for the production of yellow passion fruit seedlings at the University Vale do Rio Doce in Governador Valadares - MG, from November 2007 to January 2008. The objective was to evaluate different commercial substrates and a substrate used by small farmers in the region, associated with different rates of mineral fertilizer 8-28-16 (0, 21.4 and 42.8 g / plant) on the initial growth of two new cultivars (FB100 and FB200). We evaluated the physiological characteristics of seedlings. It was found that the cultivar FB 200 had the best vegetative growth, the substrate manure + soil was the best for cultivar FB 200, together with the plantmax® was superior to coconut fiber in the initial growth of cultivar FB 100 and the increasing rates of fertilizer stimulated the growth of seedlings.
