Influência de coberturas do solo e tipos de adubações na qualidade pós-colheita do pimentão amarelo.

Abstract

The yellow highlights show carotenoids, flavonoids and vitamin A, C and E. The soil cover can favor the cultivation of sweet pepper in the Northeast region by optimizing the use of water and proper fertilization must be done to ensure good quality and quality of fruit. "Lucia R.", cultivated with proportions of organic and mineral fertilization, under different coverings of the soil. The work was conducted in a greenhouse. The experimental design was in randomized blocks, in subdivided plots 4 x 5. The plots consisted of four coverings of the soil; soil covered with weeding; crushed carnauba straw; and uncovered soil. As subplots the fertilizations were constituted: 100% organic and 0% of the mineral fertilization; 100% of the organic fertilization and 50% of the mineral fertilization; 50% of the organic fertilization and 50% of the mineral fertilization; 50% of the organic fertilization and 100% of the mineral fertilization and; 0% of organic fertilization and 100% of mineral fertilization. An organomineral fertilization with a higher proportion of mineral fertilizer (100%) favored the yellowing of the fruits, regardless of the soil cover. A 100% organic fertilization, coupled with a 100% organic ingredient blend and 50% under-ground minerals with carnauba straw, results in less acidic chili fruits. The fruit flavor and the vitamin C content are increased with the use of soil cover with carnauba straw under 100% mineral fertilization. The carotenoid market was higher when used with uncoated soil with organomineral fertilization (100% AO and 50% AM) and mineral (100% AM).
