Abstract : Mango seeds from a seedling tree growing well in a saline soil were grown in drums in soil to which sodium chloride or sodium sulphate, alone or together, were added so as to increase the salinity from 0.5 (control) to 2-10 mmhos/cm. Data are presented on the leaf N, P, K, Ca and Mg contents of 4-month-old seedlings, and on the uptake of Na, Cl and SO4 ions. Leaf N, P, K and Mg contents were reduced at all salinity levels, the deficiencies being most marked with P and Mg. Uptake of toxic Na, Cl and SO4 ions increased at higher salinity levels.
