Physical and chemical characteristics of melon in organic farming

Melon farming is characterized as an important family agriculture activity and the organic production of fruits and vegetables has shown a large growth in terms of areas in Brazil and around the world. This work aimed to study the postharvest quality of melon cultivated in an organic system. The organic treatments constituted of base fertilizer with cattle manure vermicompost (recommended dose, ½ dose and double dose) plus the use of biofertilizer (sprayed or sprayed + irrigated), and an additional treatment with chemical fertilization. The postharvest quality was evaluated through physico-chemical and phytochemical attributes. The organic management with half the recommended dose of vermicompost plus the sprayed biofertilizer and the chemical fertilization management produced fruits with higher levels of sugar, total carotenoids, ascorbic acid and folates, obtaining more balanced fruits, with a better phytochemical quality. The antioxidant capacity was defined mainly by the presence of the phenolic compounds, which were influenced by the type and the dose of the evaluated fertilizers, with superiority in the organic treatments with double the dose of cattle manure vermicompost
