The present research entitled “Effect of growth regulators and pruning on growth, yield and quality of okra (Abelmoschus esculentus L. Moench).” was carried out at the PG research block of the Department of Vegetable Science, College of Horticulture, Rajendranagar, during Kharif- 2019. The experiment was laid in factorial completely randomized block design with three replications. Results revealed that growth regulators (NAA 150ppm, IAA 100 ppm and GA3 150 ppm), pruning and its combinations significantly improved the plant growth and flowering parameters. GA3 significantly recorded maximum Plant height (102.38 cm), internodal length (6.56 cm), leaf area (959.19 cm2) and no. of flowers per plant (17.15). GA3 treated plants also took least number of nodes to first flowering (7.09) and number of days to first flowering (44.26). Among different level of pruning, Pinching of apical buds of main stem only showed significantly maximum number of leaves per plant (21.38) and leaf area (1124.87 cm2). Number of nodes per plant (26.10) and number of branches per plant (3.33) were recorded maximum in severe pruning (Pinching of apical buds of main stem, lower and upper branches). The interaction between growth regulators and pruning has shown significant results, maximum plant height (117.07 cm) and least number of days to first flowering (38.67) and Days to 50% flowering (44.80) was observed in GA3 150 ppm in combination with Control (no Pinching).
