Salinity adversely affects physiological and biochemical processes in plants. Plants might have different methods to decrease the harmful effects of salinity, such as the accumulation of osmolytes and antioxidant compounds. An experiment was conducted in the Department of Biological Sciences, University of Sargodha, Pakistan to determine the effect of different levels of phosphorus (P) on wheat under saline conditions. Data of shoot and root fresh and dry weights, chlorophyll contents, different ion accumulation and yield components of wheat were collected. When different levels of phosphorus were applied on wheat plant under saline conditions, phosphorus reduced the effect of salinity. Applications of phosphorus decreased Na+ uptake and increased potassium concentrations, chlorophyll contents and enhanced growth of wheat plants under saline and non-saline conditions. This indicated that application of phosphorus stabilized the physiology of the wheat plants, as phosphorus activated potassium transport in wheat plants. Therefore, application of phosphorus had a positive effect on yield of the wheat plants. In conclusion, all these investigations showed that phosphorus induced the salt tolerance in wheat plants.
