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) and non-nanoparticles Zn in the form of ZnEDTA at 200 mgL 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 of 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.

氧化锌纳米颗粒对马铃薯生长、化学成分及产量的影响

在本研究中，ZnO NPs粉末被用于各种分析技术，如紫外可见光谱，如傅里叶变换红外光谱和紫外可见光谱。(FTIR)，透射电子显微镜(TEM)。透射电镜显示，ZnO纳米粒子既有小圆形纳米粒子，也有大棒状纳米粒子。氧化锌纳米粒子的紫外可见吸收光谱范围为190 ~ 1100nm。田间试验连续两个季节在埃及达卡利亚省农业研究中心的Tag El-Ezz实验研究站进行;2019年和2020年采用随机完全区组设计，研究叶面喷施纳米锌(0、20、40、60、80、100和200 mg / l)和非纳米锌(200 mg / l) ZnEDTA对马铃薯生长、化学成分和产量的影响。总体而言，喷施zn - nps能显著改善马铃薯块茎的营养生长特性，提高产量和营养成分。值得一提的是，施用80 mg / l ZnO-NPs对马铃薯大部分性状的影响最大，马铃薯块茎产量(公顷)比对照分别提高了69.89%和41.69%。
