This study investigates the effects of atmospheric-pressure dielectric barrier discharge(DBD) Plasma treatment on the agronomic performance of Brassica juncea (L.) Czern.(Brown mustard). Seeds were exposed to DBD plasma for varying durations and subsequently evaluated for germination, kinetics, seedling growth, parameters, disease registance etc. Results demonstrated that plasma treatment enhanced germination rates upto 25% compared to untreated controls with concomitant improvements in radicle elongation and seedling vigor. Treated plants exhibited increased registance to Alternari brassicae infection, corrlated with elevated activity of defense related enzymes(peroxidase, phenylalanine ammonia-lyase). Field trials revealed a 15-20% increase in harvestable yield for plasma treated cohorts. Spectroscopic analysis confirmed the generation of reactive nitrogen species during treatment ,suggesting their role in eliciting plant defense mechanisms. Notably DBD plasma application effectively reduced seed-borne pathogen load without chemical fungicides , indicating its potential as a sustainable pre-sowing treatment. These findings establish DBD plasma as a viable physical seed enhancement technology for improving productivity and disease management in B. juncea cultivation.
