The most important feature of nanotechnology in the development process of agriculture is Nano fertilizers at the 1-100 nm nanometer scale. Where, the use of nano fertilizers instead of common fertilizers provides plants with nutrients progressively and in a regulated manner, the quality of application increases, contamination decreases and the risk of chemical fertilization decreases. Therefore, Two field studies have been carried out in a private field in Derwatine Village, Nabarouh Center, Governorate of Dakahlia, Egypt, during 2016/2017 and 2017/2018 Seasons to research the impact of foliar application of chelated and nano zinc (without, spraying with chelated zinc at the rate of 2 g/liter and nano zinc at the rate of 200, 400 and 600 mg/L), nitrogen levels (100, 80 and 60 % of the recommended dose i.e. 80, 64 and 48 kg N/fed, respectively) as well as their interaction on productivity of wheat Gemmiza 12 cultivar. The experiments were conducted with three replicates in a strip-plot configuration. Five zinc foliar application treatments were given to the vertical-plots. The horizontalplots were allocated three nitrogen levels.
