This study focuses on the inhibitory effect of salinity on uptake of two macro nutrients in shoot of sorghum. Four sorghum (Sorghum bicolor (L.) Moench) cultivars viz. Pant Chari-1, Pant Chari-2, CSV-15 and HC-171 were studied in laboratory for sodium and potassium uptake under varying salt stresses. Seedlings were exposed to 0, 3, 6, 7.2, 10 and 12 EC and after ten days of starting the salt treatment, growth of shoot system and uptake of Na+ and K+ were determined. It was found that concentration of sodium ion increased while concentration of potassium ions decreased invariably from 3 to 12 EC salinities in all four genotypes. The tolerant genotype CSV-15 and HC-171 recorded minimum concentration of Na+ as compared to cultivar Pant Chari-1 and Pant Chari-2 at all level of salinity. Salinity stress negatively affected uptake of K+ in all cultivars of sorghum. Potassium ion content was highest in CSV-15 and lowest in sensitive genotype Pant Chari-2. Present study suggests that tolerance to salt stress in sorghum genotypes is related to maintain the concentrations of Na and K ions at varying salinity levels.
