An experiment was laid out in split plot design in pot culture to study the effect of sodicity, created through three NaCl stresses: 0.044% to 0.351%, 0.132% to 0.878% and 0.308 to 1.580%, on soil pH, plant height and apical dieback in Leucaena leucocephala, Albizzia lebbek, Acaica nilotica and A. ampliceps. The results indicated that the highest salt concentrations (.0.878% - 1.580%) produced deleterious changes in soil pH and resulted in dieback injury in A. nilotica, A. lebbek and L. leucocephala in an increasing order. Although the growth of A. ampliceps was reduced appreciably but it showed a fair degree of tolerance to the highest concentrations to dieback injury. The higher concentrations (0.308%, 0615%) caused highly significant reductions in plant height in A. ampliceps, A. lebbek, L. leucocephala and A. nilotica in a decreasing order.
