However, growth studies with Coffea arabica L. seedlings on the differentially treated incubated soils showed that leaf Zn reduced with increasing amounts of added P, suggesting a possible interaction of P-Zn within the plant system. Application of heavy doses of P enhanced the leaf P and growth of coffee seedlings despite its depressing effect on leaf Zn.
