An investigation on effect of growth stimulants on morphological and phenological parameters of Okra (Abelmoschus esculentus L.) cv. ArkaAnamika under soil test based nutrient management system was conducted at Central nursery, College of Horticulture, Vellanikkara, Kerala Agricultural University, Kerala, during September-December, 2016. The experiment was laid out in a randomized block design (RBD) with fifteen treatments in three replications. The okra (Abelmoschus esculentus L.) cv. ArkaAnamika 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 growth stimulants were given at 15, 30 and 45 days after sowing (DAS). The morphological and phenological parameters such as plant height, leaf area per plant, leaves per plant, branches per plant, days to 50% flowering, days to first harvest and duration of crop were significantly influenced by the growth stimulants application and soil test based nutrient management. The use of growth stimulants such as humic acid, cytozyme, and potassium silicate with soil test based modified nutrient management system improve the morphological parameters like plant height, leaf area per plant and the number of leaves per plant than control. Among the four growth stimulants used, humic acid performed better followed by cytozyme and potassium silicate.
