Foliar nutrition in apple production

Abstract

In order to create conditions conducive to sustainable fruit production, involving optimum utilization of all sources of plant nutrients with minimum environmental pollution, it is necessary to reorient agricultural producers to use those types of fertilization that are environmentally safe and appropriate which can also satisfy all fruit tree nutrient requirements. This gives particular importance to foliar nutrition as this model poses the lowest risk of soil and groundwater contamination with undesirable mineral elements. The objective of this study was to provide a comprehensive review of research papers dealing with the effect of foliar feeding on development parameters in apple trees in an attempt to obtain a more thorough insight into the advantages and disadvantages of this fertilization type and facilitate the potential use of this practice for apple producers.
