Zinc oxide (ZnO), Silver (Ag), nanoparticles were synthesised using simple chemical route which were characterised using Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Particle Size Analyzer and Raman Spectroscopy. Size of Zinc oxide (ZnO), Silver (Ag) Copper oxide nanoparticles measured 16-50 nm, 50-100 nm, respectively to conform the nano-size. Onion seeds when dry dressed with the synthesised nanoparticles each at 750, 1000, 1250 and 1500 mg kg-1, the dose of 1000 mg kg-1 outperformed in enhancing the germination (72%), shoot length ( cm) root length () and thereby the vigour index (998) compared to control (60%, , and 692) respectively. | Customizing zinc oxide ZnO and silver Ag nanoparticles for seed quality enhancement in onion Allium cepa Linn On 5
