Green synthesis of zinc oxide nanoparticles using Eucalyptus lanceolata leaf litter: characterization, antimicrobial and agricultural efficacy in maize.

ABSTRACT: In the present study, green synthesis of zinc oxide nanoparticles (ZnO NP) using Eucalyptus lanceolatus (leaf litter) extract was explored after characterization with UV spectrophotometery, Fourier Transform Infrared analysis, X-ray diffraction and TEM studies. ZnO NPs stability was ensured with - 32.1 mV zeta potential, while TEM showed ZnO NP as hexagonal structure (100 nm). In vitro antimicrobial activity showed potential of ZnO NP against pathogens causing diseases in maize plants. Both in vitro and in vivo studies of ZnO NP and ZnSO₄ (200 ppm and 400 ppm) over a two year period (2019, 2020) were conducted on Zea mays L. var. PG2458. ZnO NP seed priming improved seed vigor index, germination percentage, shoot and root length and fresh biomass. Foliar applicatio
