Abstract

Growing yellow passion fruit is a profitable activity, with a high demand for labor, and it is practiced especially by family-based farmers. However, the production cost is rather high and a significant part of this cost is associated with the expenses related to fertilization and phytosanitary treatments necessary for obtaining satisfactory yields and high commercial quality fruit. Therefore, the objective of this study was to evaluate the effect of using organic compound in fertilization of plants and alternative products in phytosanitary treatments on the yield and quality of fruits. Yellow passion fruits were submitted to three types of fertilization (mineral, organic and organic-mineral) and two types of phytosanitary treatment (‘conventional’ and ‘alternative’). This experiment evaluated fruit yield (kg/plant) and fruit quality by using the following evaluations: seedless pulp yield, soluble solids content (SS), titratable acidity (TA), SS/TA ratio and vitamin C content. The different types of fertilization did not interfere in fruit yield, however, plants under conventional phytosanitary treatment displayed higher yields. The SS content and TA of the fruits were influenced only by fertilization, where plants that received mineral and organic-mineral fertilization produced fruit with higher contents of SS and TA. Pulp yield, SS/TA ratio and vitamin C content were not influenced by any of the evaluated factors. Regarding cultivation of passion fruit, it is possible to substitute some mineral fertilizers for organic fertilizers with no negative effects on the fruit yield or quality. However, the substitution of pesticides for alternative products compromises fruit yield.
