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. Among different methods of application foliar spray recorded significantly maximum vegetative growth, early flowering, improved quality and higher yield in comparison to dipping method. Application of GA3 at 250 ppm concentration through foliar spray recorded significantly highest number of leaves (137.62), leaf area index (5.10), lowest number of days to reach to 50% spike emergence (100.35), longest spike length (103.77 cm), spike weight (93.25 g), number of florets per spike (64.34) and yield of spikes per hectare (3.42 lakhs/ha). Thus, foliar spraying of GA3 at 250 ppm concentration proved to be ideal to realize higher spike yield in tuberose.
