Abstract

In this study ZnO NPs powder was used hence various analytical techniques, such as UV–Visible spectroscopy, such as Fourier transform infrared spectroscopy and UV-Visible spectroscopy. (FTIR), Transmission Electron Microscopy (TEM). TEM revealed both ZnO NPs small round nanoparticles and big rod nanoparticles.Zinc oxide nanoparticles' UV-vis absorbance spectrum, which ranges from 190 nm to 1100 nm. Field experiment was done in the Tag El-Ezz Experimental Research Station of the Agricultural Research Center in the Egyptian governorate of Dakahlia, during two successive seasons; 2019 and 2020 to assay the effect of foliar spraying with nanoparticles (NPs) of Zinc (0, 20, 40, 60, 80,100 and 200 mgL^-1) and non-nanoparticles Zn in the form of Zn- EDTA at 200 mgL^-1 with a randomized complete block design on the growth, chemical composition and yield of potato (Solanum tuberosum L.). In general Spraying Zn0-NPs onto leaves greatly improved the vegetative growth characteristics, yield and improved nutritional contents of potato tubers. It is worthy to mention that, 80 mgL^-1of ZnO-NPs have the highest effect on most characters and increase the yield of potato tubers (ha) by (69.89 and 41.69%) compared to control during the two seasons.
