Abstract
Zinc oxide (ZnO), Silver (Ag) and Titanium dioxide (TiO2) nanoparticles were synthesised using template-free aqueous solution based on simple chemical route which were characterised through SEM, TEM and XRD. Size of Zinc oxide (ZnO), Silver (Ag) and Titanium dioxide (TiO2) nanoparticles measured 35-45nm, 20-80 nm and 85-100 nm, respectively to conform the nano-size. Groundnut seeds when dry dressed with the synthesised nanoparticles each at 500, 750, 1000 and 1250 mg kg -1, the dose of 1000 mg kg-1 outperformed in enhancing the germination (75%), shoot length (20.97 cm) root length (17.98) and thereby the vigour index (2949) compared to control (55%, 16.92, 15.21 and 1759) respectively.
