The quality and yield of an agriculture crop are highly dependent on uniform and rapid germination of the seeds. Pre-sowing hydropriming is one of the most suitable, reasonable, easily available, and highly costeffective environment friendly techniques for improving seed quality and enhanced seedling growth. Henceforth, a laboratory experiment was conducted to assess the effect of hydro-priming duration on germination and seedling growth of lentil. The experiment was laid out in two factor Completely Randomized Design (CRD) with three replications and five treatments including different hydro-priming durations (Control, Hydropriming for 12 hours,14 hours, 16 hours and 18 hours) in two varieties namely PDL 1 and IPL 316. Hydropriming seeds for 16 hours significantly improved their performance compared to non-primed seeds in both of these varieties tested. The results showed an increase in speed of germination by 53% and 69%, a boost in germination rate by 12.6% and 8.2%, and enhancements in Vigour Index I by 36% and 12%. Additionally, Vigour Index II increased by 27.8% and 7.4%.In both of these varieties, the highest seed quality parameters were recorded in the 16 hours of hydroprimed seeds whereas the lowest seed quality parameters were observed in non-primed seeds. Overall, from this experiment it was concluded that 16 hours of seed hydro-priming duration proved to be an effective method for enhancing seed germination and vigour.
