Two field experiments were carried out at the experimental farm of the
Horticulture. Research station, south EI- Tahrir, Menufyia. Governorate, Egypt in
200012001 and 200112002 growing seasons to study the effect of zinc application at
different rates, sources and methods on yield components and some chemical
properties of wheat (variety Giza 163). The results coutd be summarized as follow: ,. AU yielrl and yield components, characters were significantly increased by different
zinc application treatments compared with control. The promising treatment was
applying 0.12% zinc chelate as foliar spray. 2· Nitrogen, phosphorus, Potassium, and Zinc content of grain were increased with
applying Zinc compared with control. The highest values were recorded by 0.12%
