Abstract
Information about the local response to fertilization in pecan trees is very limited.
Here, we investigated the effects of fertilization with different levels of nitrogen (N), phosphorus (P) and zinc (Zn) on the chemical composition of leaves of pecan trees of the Stuart cultivar.
Fertilization had a positive impact on foliar N concentration, a negative impact on foliar P concentration, and no effect on foliar Zn concentration.
A negative linear relationship was found between foliar N concentration in fall and protein content in the embryo.
