An investigation on the effect of salicylic acid, ascorbic acid and thiourea on morphological parameters of Okra (Abelmoschus esculentus L.) cv. ArkaAnamika under drought stress was conducted at Regional Agricultural Research Station, Pilicode, Kerala Agricultural University, Kerala, during December 2019 – March 2020. The field experiment was laid out in a randomized block design (RBD) with eight treatments in three replications. The okra (Abelmoschus esculentus L.) cv. Arka Anamika was raised as per standard package of practices recommendations of Kerala Agricultural University and also under soil test based nutrient management system. Foliar applications of salicylic acid (1 mM and 2 mM), Ascorbic acid ((1 mM and 2 mM) and thiourea (500 and 1000 ppm) were given at 10, 15 and 30 days after sowing (DAS). Drought was induced 25 days after sowing (DAS) and irrigation given at 50% field capacity. The morphological parameters such as plant height, leaves per plant, branches per plant, root volume and duration of crop were recorded at 25, 50 and 75 DAS. The morphological parameters such as plant height, leaves per plant, branches per plant, root volume and duration of crop were significantly influenced by the foliar spray of salicylic acid, ascorbic acid and thiourea. Among these chemicals, salicylic acid 1 mM performed better followed by ascorbic acid 2 mM.
