A field trial was conducted to evaluate the efficacy of GA3 tablets (soluble in water) in grapes for improving the quality and yield. The trial was conducted during the season 2016-17 in grower’s vineyard located at Pandharpur (M.S.), India. The experiment was performed on Manik Chaman grape variety which was grafted on Dogridge rootstock. Different treatments of Gibberellic acid tablets (GA3 93%) and powders (GA3 90%) were applied at flowering, 3-4 mm berry stage and 6-8 mm stage of berry development. The observations of bunch weight, 100 berry weights, berry length, TSS, Acidity and yield parameters were taken at harvest. The data showed significant differences in mean bunch weight, berry size, quality and yield parameters. The mean bunch weight was recorded maximum in GA3 tablets when applied @ 40 ppm (372 g) treatments whereas it was found lowest in no application of GA3 (235.7 g). The berry sizes, skin thickness and yield per vine were also recorded significantly highest in GA3 applied plants. No symptoms of any abnormality, toxicity were found either on the leaves, canes, shoot or in grapes berries with the application of GA3 tablets up to 80 ppm concentration.
