A field test was done at the Experimental Station Farm, Faculty of Agriculture, Mansoura University, during 2015 season to think about the impact of zinc application on development, yield and its component of maize (Zea mays L.) single Cross half and half 168 (SC 168) developed in alluvial soil. The trial was done in a total randomized block outline with three duplicates. The acquired outcomes demonstrated that the best treatment was utilizing ZnSO₄.H₂O as a foliar splash (0.75 g L^-1) Zn₄. That is, on account of developing a plant, the seeds can be utilized for Zn₂. On account of developing plant to get the leaves of the plant as a green plant (silage), Zn₃ can be utilized.
