摘要

The present research focusses on the green synthesis of silver nanoparticles (AgNPs) using Jeevamrutha, a traditional fermented bio-formulation abundant in bioactive chemicals and microbial consortia, as a natural reducing and stabilising agent. The synthesized AgNPs were characterized by UV–Vis spectroscopy, FTIR, XRD, FESEM, and EDS, confirming their spherical morphology, face-centered cubic crystalline structure, an average particle size of ~ 62.5 nm, and high elemental silver content (72.4%). Antimicrobial assays revealed broad-spectrum inhibitory effects, with the highest activity observed against Bacillus megaterium. Pot experiments showed that seed priming with 30 µg/mL AgNPs significantly increased germination percentage, root and shoot growth, leaf area, biomass, chlorophyll content, and relative water content of Spinacia oleracea under saline conditions (4 and 6 dS m⁻¹), while reducing electrolyte leakage, hydrogen peroxide accumulation, proline, and glycine betaine levels compared to untreated controls. These findings highlight Jeevamrutha-mediated AgNPs as an economical, eco-friendly, and scalable approach for enhancing salinity tolerance in crops, offering potential to reduce reliance on synthetic agrochemicals and promote sustainable agriculture.
