Increasing levels of RSC in irrigation water decreased the electrolyte concentration (ECe), soluble calcium, magnesium and sodium and exchangeable calcium and magnesium content of the soil. However, an increase in pH, soluble carbonates and bicarbonates and exchangeable sodium was recorded as a consequence of rise in RSC levels of irrigation water. A higher dry matter accumulation, root weight, and a lower Na/K ratio in plants of genotype SR-16 and Arjuna were recorded as compared to other genotypes under study showing a higher degree of tolerance to RSC levels in irrigation water. Further, a deterioration to higher degree in physico-chemical properties of the soil and reduction in growth and uptake of nutrients by foxtail millet plants were apparent on clay loam soil as compared to sandy loam soil.
