Abstract
Silver nanoparticle (AgNPs) is one of the widely used nanoparticles because of their antimicrobial properties. In this present study, the effect of green synthesized silver nanoparticles and bulk form of silver (AgNO3) at different concentrations (250, 500, 750 and 1000 ppm) on seed quality parameters of groundnut were studied. Silver nanoparticles synthesized using Azadirachta indica leaves were characterized by Dynamic light scattering, UV- Vis and FTIR spectrum. Size, zeta potential, UV- Vis absorbance peak and FTIR spectrum of the AgNPs measured 28.6 nm, 24.6 mV, 350 to 490 nm and 3334.53 cm-1 respectively. The results showed that AgNPs 1000 ppm was found best in enhancing the seed quality parameters such as germination percentage, root length, shoot length, seedling length, root dry weight, shoot dry weight, seedling dry weight, seed vigour index I& II.
