An investigation was carried out to find out the effect of different plant growth regulators by foliar spray and dipping treatment on growth and spike yield of tuberose cv. Suvasini. Experiment was conducted in a two factorial randomized block design with four growth regulators each at two concentrations and two methods of application. Application of GA3 at the rate of 250 ppm recorded significantly early sprouting and lowest number of days required to reach to 50% sprouting of bulbs. | Effect of growth regulators and methods of application on vegetative growth and spike yield of tuberose Polianthes tuberosa L. cv.
