Abstract: 

Nanotechnology is one of the modern technologies that are involved in many fields, including agriculture. The goal of this research is to manufacture nano-zinc oxide by sol-gel method and measure the size of the manufactured particles, and then apply them to celery seeds. At first, nanoparticles of zinc oxide were prepared by sol-gel method Several techniques were used to characterize the prepared nanoparticles, including infrared spectroscopy (FTIR), ultraviolet spectroscopy (UV), X-ray diffraction measurement (XRD) and dynamic light scattering technology DLS with a zeta sizer device, which was prepared from zinc oxide nanoparticles of six gradient concentrations. of ZnO-NPs (5, 20, 40, 60, 80 and 100) mg/l, Bulk zinc oxide and zinc sulfate were prepared in the same concentrations as above, and celery seeds were soaked for four hours, and then transferred to sterile Petri dishes. The results showed, depending on the characterization methods used, the success of the formation of zinc oxide particles, and the size of these particles was about (12) nm, and the seeds treated with ZnO-NPs were significantly affected by giving the highest germination indicators compared to other treatments. We can conclude through this study the importance of using ZnO-NPs to improve productivity and growth of agricultural crops.

Keywords: Nanotechnology, nano- zinc oxide nanoparticals, growth indicators, celery.
