Abstract: A plug tray experiment for identification of early stage salt stress responses in tomato seedling under iso-osmotic stress was conducted under net house condition. An experiment was laid out in completely randomized design with factorial concept having ten treatment combinations comprising of two levels of sources of stress: PEG-8000 and NaCl and five levels of water potential viz., -0.2MPa, -0.4MPa, -0.6MPa, -0.8MPa, and -1.0MPa beside one control treatment. The treatments were replicate thrice and the effects of these treatments on Na+ and K+ content in leaves, shoot and root were studied. From the experimental results it was indicated that NaCl induced stress had significant effect on leaves, shoot and root Na+ and K+ content. Na+ content was recorded higher in leaves followed by shoot and root at -1.0MPa and K+ content was higher in leaves followed by shoot and root under lowest water potential of -0.2 MPa. However, PEG-8000 had non-significant effect on both Na+ and K+ content in leaves, shoot and root accumulation.
