Abstract: Black gram [Vigna mungo (L.) Hepper] is one of the most important pulse crops grown in India. India is the largest producer and consumer of black gram in the world. Salt stress is one of the most serious limiting factors for growth and production in most of the crops and salicylic acid an important phenolics known to alleviates its adverse effect. Thus, the green house experiment was conducted to investigate the effect of exogenous application of salicylic acid (SA) under salt stress on physiological, biochemical parameters and enzymatic activities of black gram. The experimental design was factorial completely randomized design with four salicylic acid concentrations (0.0, 0.5, 1.0 and 1.5 mM), four level of irrigation to induce salinity stress (< 2 EC-tap water, 4.0 EC, 6.0 EC and 8.0 EC). The pots were irrigated with different concentration of saline water and plants were sprayed with salicylic acid after 20 and 40 DAS (Days after Sowing), samples were withdrawn after 21, 41 and 61 DAS for the analysis. The observations were recorded for the antioxidant enzymes viz, polyphenol oxidase, peroxidase and catalase. Antioxidant enzymes activities like peroxidase and polyphenol oxidase in leaf was increased with higher concentration of salt stress however, the catalase activity was decreased. Antioxidant enzymes activity showed similar trends. Higher dose of salicylic acid decreased the catalase and polyphenol oxidase enzyme activity.
