GARCIA-MARTINEZ, René et al. Yield, quality and post-harvest behavior of ‘Hass’ avocado fruits of orchards with different fertilization. Rev. Mex. Cienc. Agríc [online]. 2021, vol.12, n.2, pp.205-218.  Epub Apr 25, 2022. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v12i2.2232.

In fruit trees, productivity differs between orchards due to the particular condition of the nutritional status of trees, soil fertility, rootstock, crop health and agronomic management. The objective of this research was to compare the yield, quality and post-harvest behavior of ‘Hass’ avocado fruits in two orchards with different fertilization management. The first was located in Valle de Bravo and the second in Villa de Allende, State of Mexico. The evaluation was carried out in 2017. In each orchard the yield, quality, post-harvest behavior and extraction of nutrients by the fruits were measured. In addition, the tree's nutritional status and soil fertility were diagnosed. The fruits of the Valle de Bravo orchard surpassed those of Villa de Allende in yield, weight, length, diameter and oil concentration and density, however, they had less firmness and weight loss. The avocados of Valle de Bravo had higher concentration of K, S, Zn and B, those of Villa de Allende concentrated more Ca, Fe, Cu and Mn. In Valle de Bravo the trees showed deficiencies of Ca, S, Cu, Mn, Zn and B, while, in Villa de Allende, the deficient elements were K, S, Zn and B. In conclusion, the highest yield of fruit obtained in the Valle de Bravo orchard was related to the better nutritional status of the trees and increased soil fertility.
