Abstract: In order to study the response of wheat growth, yield, yield characteristics and grains chemicals analysis to zinc (Zn) foliar treatments under top dressing of potassium (K) fertilizer levels, two field experiments were conducted at the Experimental Farm, Faculty of Agriculture, Mansoura University, Egypt, during 2017/2018 and 2018/2019 seasons.The experiments were laid out in a strip-plot design with three replicates, each experiment comprising of twenty-five different treatments of five zinc foliar application treatments (without as control, spraying with water, 150, 300 and 450 g Zn/fed) were allocated at the vertical-plots.While, the horizontal-plots were devoted to five potassium fertilizer levels (0, 14, 28, 42 and 56 kg K2O/fed) as top dressing.The results showed that zinc foliar application treatments significantly increased growth, yields and its attributes and grain quality of wheat plants and the highest values of all characters under study were recorded with 450 g Zn/fed compared with the other foliar application in both seasons.Potassium fertilization positively enhanced the growth, yield characters and grains quality of wheat.Application of 56 kg K 2 O/fed produced the highest values of most studied traits and without significant differences with 42 K 2 O/fed as compared with other potassium levels during both growing seasons.Therefore, the current study detected that foliar application with 450 g Zn/fed), besides potassium soil addition at 42 K 2 O/fed to improve the productivity and grain qualities of wheat Gemiaza11 cultivar under the same environmental conditions of the agriculture area.
