A solution culture pot study was carried out to see the effect of two contrasting salt species i.e., NaCl and Na2SO4 on the growth and physiology of spring wheat. Na+ concentrations in both the salt species were 0, 50, 100 and 200 mM. A significant difference was observed in case of osmotic pressure of sap which indicated that NaCl had a greater effect on osmotic pressure. There were non- significant difference between the two salt species for leaf area, K+, Na+ contents and K+/Na+ ratio. A significant increase in osmotic pressure and Na+ content in sap was observed with increasing Na+ concentrations whereas leaf area, K+ contents of sap and K+/Na+ ratio decreased with increasing Na+ concentrations. Leaf area of the flag leaf was significantly higher in case of Na2SO4 as compared to NaCl treatments.
