Substrates and fertilization are fundamental for seedling production, which well nourished can produce earlier and are more resistant to stresses. Animal manures are often used in non-industrialized substrates with good results, but their costs are increasing. Other residues may be used for plant nutrition, in substrates or in leaf fertilization. The aim of this work was to evaluate substrates prepared with green manure composts and the leaf application of biofertilizer on the formation of yellow passion fruit seedlings. A greenhouse experiment was conducted between December 2009 and February 2010, with a split-plot random block design. Plots received or not leaf application of supermagro biofertilizer. Subplots consisted of different substrates: soil; soil + cattle manure; soil + cattle manure composted with black oats straw; soil + cattle manure composted with ryegrass straw; soil + cattle manure composted with turnip straw; and soil + cattle manure composted with vetch straw. There were three dates of leaf fertilization: 10, 25 and 40 days after emergence (DAE). At 50 DAE plants were collected for evaluation of growth and accumulation of biomass and nutrients: N, P, K, Ca, Mg, Cu, Mn and Zn. Data were submitted to analysis of variance and means compared by Tukey test. The substrate soil + cattle manure promoted higher stem diameter, plant height, leaf area, root length and volume and nutrient accumulation. Among substrates with green manure composts, those prepared with black oats and turnip straw outranked the others. The use of leaf biofertilizer showed diverse results on seedling formation, being beneficial when combined to substrates with black oats composted straw, and prejudicial when combined to soil + cattle manure and soil + turnip composted straw substrates. The accumulation of nutrients by the seedlings occurred in the following order: K>Ca>N>Mg>P>Zn>Cu=Mn.\ud \u
