The rationale for the decrease of fruit yield in Fe deficient trees
has to be found in the decreased assimilatory power caused by Fe
chlorosis (Álvarez-Fernández et al., 2006). In our case, in spite of the
evident chlorotic leafy symptoms, almost all the values of nutrient
in leaves were in the optimum range, with the only exception of
magnesium (Embleton et al., 1973). For this reason no clear effect
on yield and fruit quality was noticed.
