Two field experiments were carried out during two summer seasons of 2018 and 2019 at the Experimental Farm of the Faculty of Agriculture, Assiut University, Assiut, to study the response of two maize hybrids [Single Cross (S.C.) 10 (H₁) and Trible Cross (T.C.) 321 (H₂)] on yield and its components of three micro-nutrients (M₁= B, M₂= Zn and M₃= Mn) and three foliar spray levels= control (water only), S₁= (25 ppm B, 50 ppm Zn and 34 ppm Mn) and S₂= (50 ppm B, 100 ppm Zn and 68 ppm Mn). Experimental design was randomized complete block design (RCBD) using split-plot in strips, where nutrients allocated in the main vertically, foliar spray levels were arranged in the main horizontally and maize hybrids were occupied the sub-plots.
