GARCIA MARTINEZ, René et al. Ripening and fruit quality of mango 'Kent' with three levels of fertilization. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.4, pp.665-678. ISSN 2007-0934.

The annual fertilization program plays an important role in the management of the garden and its efficiency depend largely, production and fruit quality. A balanced fertilization consider the amount of nutrients available in the soil, including those used by the tree for their development and they are removed by the production of fruit, ensuring adequate supply of macro and micro elements. The objective of this research was to evaluate the effect of fertilization program on changes in the variables related to the maturation and fruit quality of mango 'Kent' from an experiment installed in a commercial orchard in Acaponeta, Nayarit, Mexico, where three levels of fertilization were applied (g tree^-1): regular (381 de N, 367 de P₂O₅, 296 de K₂O, 296, 688 Ca, 84 Mg, Fe 14, 9 Mn, 5 Zn and 45 B), high (50% more of each element of the regular dose) and control (without fertilization). The fertilization affected the nutrient concentration of fruit. Differences were presented in profiles the total respiratory rate, firmness, soluble solids (TSS), citric acid, ascorbic acid and sugar/acid ratio also the presence of nitrogen in levels of regular and high fertilization increased the green hue of the background colour of the fruits. It was concluded that the quality and shelf life of fruits was affected by fertilization levels applied.

Keywords : Mangifera indica; colour; firmness; nutritional content; respiration rate.
