Drought stress is one of the major physiological stresses especially in arid and semiarid regions that severely affected crop production meanly leguminous crops. A pot experiment was carried out to assess growth, yield, biochemical and antioxidant contributing characters under semi-controlled environmental condition in the Department of Biological sciences, Sam Higginbottom University of Agriculture Technology and Sciences, Allahabad, India. During November 2016 through March 2017 aiming to alleviate the drought stress effects on chickpea using salicylic acid (SA). Chickpea varieties C1021 and C1022 were used in the experiment. The experiment was conducted using Completely Randomized Design (CRD) in three replications with five levels of drought stress and Salicylic acid concentrations (T0: control, T1: 0.5 mM SA + 25, 50, 60 DAS of irrigation, T2: 1.0mM SA + 25, 65 DAS of irrigation, T3: 1.5mM SA+ 25, 50 DAS irrigation, T4: 2.0mM SA+25, 50 DAS of irrigation), even 0.3% potassium iodide at anthers formation. Different concentration of SA was applied as foliar spray and spraying was done on 30, 45 and 60 DAS. The data for chlorophyll content in leaf and relative water content (RWC), harvest index, antioxidant like proline, APX, SOD, H2O2, POD, MDA were observed. Yield and yield contributing characters were measured at maturity. Growth parameter was observed at different intervals of 30, 60, 90DAS. The results showed that drought decreased total dry weight, chlorophyll content, relative water content, plant height, number of branches, number of pods/ plant, pod length, 100-seed weight, number of seed/ pod and yield of chickpea. Foliar application of SA was highly significant (T3), then (T2) and then control (T0) of all two varieties best result observed in C1021 and C1022. At different doses under different drought stress conditions had the positive effects related to mitigation of drought stress effect but concentration at i.e., SA @ 1.5mM, respectively were found to alleviate the adverse effects significantly on the above parameters at drought condition.
