The role of some agricultural practices and fertilizer type on both the incidence of stem borers infestation and corn yield in Egypt.

Maize, Zea mays, L. is one of the most important field crops in Egypt. It is used mainly for human, animal and poultry feeding.

Effect of sequential applications of foliar nutrients, biofertilizers and sowing dates on the incidence of corn stem borers in Egypt.

In this study either early sown (May 1st) or lately sown (June 2nd) corn plants were treated with Phosphorin & Rhizobactrin as biofertilizers and sprayed with six selected foliar nutrients, i.e. Polymex; Greenzit SP100, Greenzit NPK, Potasin-F, Copper sulphate and Ascorbic acid; in mono-, bi-, and/or tri-sequential applications.
