Soil salinity is one of the major productions limiting factor saline soil. In Pakistan about 5.7 m ha have been deteriorated partially or completely by salinity or sodicity. To alleviate the adverse effects of salinity stress on plants in salt affected soil, there are two approaches: one to reclaim these soils by applying chemical amendments to make it suitable for good crop production and other is the use of salt tolerant plant species. Tolerance of crop to salinity varies not only among species but also among the varieties of the same crop. The book in hand furnishes baseline information on the subject for the researchers, agriculture graduates and policy makers and allied stalk holders.
