It was evaluated the effects of the organic fertilization in development, production and fruits quality of sweet passion fruit (Passiflora alata Dryand). As an organic fertilizer, it was used cattle manure (50%, 100%, 150% and 200% of the recommended dose for the culture) and the control treatment. The experiment was conduced in Botucatu/SP, in a Red Nitosoil. It was evaluated length and diameter of the branches, number of fruits, fruits diameter, fruits weigh, pulp production, pH, acidity (g citric acid/100g of fruit), total soluble solids (°Brix) and the relation SST/ATT ("Ratio"). The best results were obtained with the dose of 100% (5kg of cattle manure plant-1. This treatment showed better quality, larger number of fruits and larger production.
