With the purpose of evaluating the influence of substrate on the development of yellow passion fruit, an experiment in a greenhouse at Embrapa Cerrados Station has been conducted. The experimental design was a randomized block in a factorial scheme 2 x 4 x 3 x 2, totalizing 48 treatments, 18 useful plants by plot and four replications. The treatments had consisted of combinations of: two commercial substrate (Plantmax^R ¾ to the base of Vermiculite^R plus pines bark and Vermiculite^R ¾ to the base of Vermiculite^R); three organic sources ¾ f.o. (humus, cows manure and Nutriplanta^R (product base of bacteria) and absence of f.o., in the ratio of 3:1 of the basic substrate for f.o.; two formulated fertilizers [Osmocote^R as 14-14-14 (product of slow release of nutrients) and 4-14-8, of normal release], besides the absence of fertilizer and, absence and presence of Glomus etunicatum. The artificial substrate Plantmax^R was upper than the Vermiculite^R in all the analyzed features. Among the f.o., the Nutriplanta^R with cows manure had provided the best performance. The Osmocote^R promoted the biggest development of seedlings, followed by 4-14-8. The presence of absence of f.o. matched with Plantmax^R practically did not influence the analyzed features. It must not use Glomus etunicatum associated the Plantmax^R, due to the high phosphorus content in this substrate.
