A substrate consisting of industrial sugarcane plant residues has been used with success to the production of some fruitful and forest species seedlings. Then, the objective of this research was to evaluate the use of that substrate, comparing it with other substrates recommended to the production of yellow passion fruit seedlings. It was evaluated seven substrates: 1- Sugarcane bagasse + industrial sugarcane plant residues (3:2; v:v); 2- Sugarcane bagasse + industrial sugarcane plant residues (3:2; v:v) + NPK foliate spray weekly; 3- Sugarcane bagasse + industrial sugarcane plant residues (3:2; v:v) + 7.3 kg m-3 of Osmocote® (14-14-14); 4- Plantmax®; 5- Plantmax® + NPK foliate spray weekly; 6- Plantmax® + 7.3 kg m-3 Osmocote® (14-14-14) and 7- Sand + manure + vermiculite (1:1:1; v:v:v) + NPK. In general, the seedlings cultivated in the substrate consisting of industrial sugarcane plant residues and in the Plantmax®, both fertilized with Osmocote®, were the ones that presented better nutritional status checked by the appropriate nutrients levels associated to a great growth. Therefore, the substrate composed by the mixture sugarcane bagasse + industrial sugarcane plant residues (3:2; v:v) fertilized with 7.3 kg m-3 of Osmocote® (14-14-14) can be used for the production of yellow passion fruit seedlings.
