Abstract: Salinity is a major environmental constraint influencing plants productivity and plant distribution worldwide. Salinity reduces the ability of plant utilize water and causes a reducing in growth rates, as well as changes in plant metabolites processes. In Indian context, cowpea (Vigna unguiculata L. Walp) is a minor pulse cultivated mainly in arid and semi arid regions. Salt stress is one of the most serious limiting factors for growth and production in most of the crops including cowpea and silicic an important phenolics, gibberellic acid an important growth hormone, potassium nitrate known to alleviates its adverse effect. Thus, Green house experiment was conducted to investigate the effect of exogenous application of gibberellic acid, potassium nitrate and silicic acid under salt stress on physiological, biochemical parameters in seedlings of cowpea. The result suggest that biochemical constituents viz., total soluble sugars, reducing sugars and proline that increase under salt stress conditions while, the physiological parameter like relative water content that decreased. On an application of GA3, KNO3 and silicic acid under salt stress increased total soluble sugars, reducing sugars, proline. This investigation has suggested a silicic acid, gibberellic acid, potassium nitrate as a potential biomolecules affected the various biochemical and physiological parameter under abiotic stress like salinity.
