MEDINA-MENDEZ, Juan et al. Nutrient status and fruit yield of mango trees (Mangifera indica L.), cv. Tommy Atkins, in luvisols soils in Campeche state, Mexico. Rev. Chapingo Ser.Hortic [online]. 2014, vol.20, n.3, pp.253-268. ISSN 2007-4034. https://doi.org/10.5154/r.rchsh.2012.12.067.
The nutrient status of mango trees (Mangifera indica L.) growing in Luvisol soils in Campeche, Mexico, was studied in order to identify possible deficiencies and, if necessary, decide on the need for fertilizer applications. Soil and leaf samples were collected in 48 commercial mango orchards to quantify physical and chemical properties and nutrient concentrations, respectively. Information on orchard management and fruit yield was also obtained. Regression models for predicting crop yield, based on leaf nutrient concentrations and physical and chemical soil properties, as well as technological factors, were estimated. Nutrient sufficiency ranges as an expression of the nutrient status of the trees were established. The adequate sufficiency ranges for the various nutrients were: for N, 0.90 to 1.35 %; P, 0.07 - 0.11 %; K, 0.5 - 0.8 %; Ca, 3.5 - 3.75 %; Mg, 0.16 - 0.25 %; Fe, 75 - 140 mg·kg-1; Mn, 175 - 320 mg·kg-1; Cu, 6 - 9 mg·kg-1; Zn, 10 - 22 mg·kg-1; and, B 85 - 210 mg·kg-1. Based on the distribution of the orchards in the sufficiency ranges, it was observed that there are orchards that would require fertilizer applications: P (48 %), K (52 %), Ca (62 %), Mg (56 %), Fe (73 %), Cu (65 %) and B (44 %). By contrast, the deficiencies are lower for Mn (17 %) and Zn (21 %) and were not observed for N.
