This experiment was conducted on rice (cv. 2005 Thaoi) seeds to study whether priming with deep sea water (DSW) re-sults in enhancement of seed emergence and seedling growth and to identify the optimum concentration of Dep Sea Water (DSW)40%), and in experiment 2, five concentrations of DSW(10%, 15%, 20%, 25%and 30%) were prepared and seeds were primed for24 hours duration at 25 . Beside this, hydro priming with plain water was also included as a control. Experiments were laid out in℃CompletelyRandomizedDesign(CRD)withthrereplications.
