THE SUBSTRATE INFLUENCE ON THE DEVELOPMENT OF SEEDLINGS OF YELLOW PASSION FRUIT (Passiflora edulis Sims f. flavicarpa DENEGER). Rev. Bras. Frutic. [online]. 2001, vol.23, n.2, pp. 377-381.

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 (PlantmaxR ¾ to the base of VermiculiteR plus pines bark and VermiculiteR ¾ to the base of VermiculiteR); three organic sources ¾ f.o. (humus, cows manure and NutriplantaR (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 [OsmocoteR 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 PlantmaxR was upper than the VermiculiteR in all the analyzed features. Among the f.o., the NutriplantaR with cows manure had provided the best performance. The OsmocoteR promoted the biggest development of seedlings, followed by 4-14-8. The presence of absence of f.o. matched with PlantmaxR practically did not influence the analyzed features. It must not use Glomus etunicatum associated the PlantmaxR, due to the high phosphorus content in this substrate.
