Plant growth, nutrient uptake, pigments, and oxidative stress attributes of salt tolerant (SARC 1) and salt sensitive (SARC 5) wheat genotypes exposed to 100 mM NaCl with and without potas-sium (K) and humic acid (HA). Plants supplemented with combined K and HA showed better salt tolerance and biomass production than without K and HA. Greater salt tolerance of SARC 1 than SARC 5 is mainly attributed to limited uptake of Na and higher activities of antioxidants.
