ABSTRACT
Tuberose (Polyanthas tuberosa), is an important ornamental and perfumery plant. The research was conducted at University of Swabi during summer 2018 to evaluate the performance of tuberose under various concentrations of gibberellic acid and micronutrients. Experiment was laid in Randomized Complete Block Design (RCBD) using two factors i.e. gibberellic acid and micronutrients with three replications. Both the factors gibberellic acid (GA3) and micro nutrients had their significant effects. The best performance was found in the interaction of GA3 and micronutrients for plant height (53,21cm), number of leaves (16.34), length of spike (77.68cm), diameter of spike (7.51cm), floret number (25.27) and length of rachis (16.1cm) at 150 ppm gibberellic acid and 3000 ppm micro nutrients and hence recommended for increasing growth and flowers in tuberose.
