Humic acids reduce the addition of NPK and improve the quality of mango

The objective of this study was to demonstrate that humic acids (AH) reduce the use of chemical fertilizers and increase the quality of mango cv. Ataulfo. A completely randomized design with a 3x2 factorial arrangement was used. The evaluated treatments were three doses ofNPK (70, 100 and 130%) and...

Descrição
Resumo:The objective of this study was to demonstrate that humic acids (AH) reduce the use of chemical fertilizers and increase the quality of mango cv. Ataulfo. A completely randomized design with a 3x2 factorial arrangement was used. The evaluated treatments were three doses ofNPK (70, 100 and 130%) and two doses of AH (70 and 100 g plant−1 ). The results showed that when applying 70% NPK in combination with 100 g plant−1 of AH, a significant difference was obtained in the highest freshweight and polar diameter of the fruit; while, when adding 130% of NPK with 70 g plant−1 of AH, the highest content of total soluble solids and titratable acidity was achieved; while the highest content of vitamin C in the fruits was reached when applying 100% NPK with 100 g plant−1 of AH.
