Salinity  toxicity normally results when certain ions are taken up with the soil- water and  accumulate in the leaves during water transpiration to an extent that result in damage to the plant.  The degree of damage depends upon time, concentration, crop sensitivity and crop water used, and if damage is severe enough, crop yield is reduced.  The usual toxic ions in irrigation water are chloride, sodium and boron.  Damage can be caused by each, individually or in combination. In India growth responses of Dalbergia sissoo and Acacia nilotica seedlings on different levels of soil sodicity and salinity. The growth and dry weight of one-year old seedlings decreased as the level of sodicity and salinity increased in both species. However, the suppression in growth caused by sodicity and salinity was relatively greater in D. sissoo than in A. nilotica. A. nilotica showed wider response breadth compared with D. sissoo on both the gradients. Further, the response breadths were comparatively higher under sodicity levels than under salinity levels. Dalbergia sissoo in its natural and man-influenced ecosystem was being adversely affected by various abiotic stresses. Studies undertaken on the physio-chemical characteristics of soil under dead and healthy trees of Dalbergia sissoo and to correlate soil factors with the decline of shisham in semi-arid regions revealed that the pH, ECe, bulk density and calcium carbonate was found higher in soil under dead trees as compared to healthy trees. The value increased with increase in soil depth. The organic carbon and macro-nutrient (i.e. N, P, K, Ca, Mg and S) and micro-nutrients (Zn, Fe, Cu, and Mn) were  higher under healthy trees as compared to dead trees and their concentrations decreased with increase in soil depth both in case of healthy as well as dead trees of Dalbergia sissoo.
