Abstract: An experiment was laid out with four spacing’s (30x20cm, 30x30cm, 45x20 cm, 45x30 cm), three bulb sizes (<2.0 cm, 2.0-3.0 cm and >3.0 cm) and two depths of planting (2.5cm and 6.0cm) in a randomized block design with three replications to study their individual and interaction effects on vegetative growth and flower yield in tuberose cv. Suvasini. All vegetative growth parameters except total chlorophyll content and all spike quality parameters spike for girth were found significantly influenced with wider spacing (45x30cm). Longivity of the spike on the field was found significantly maximum (15.77 days) with wider spacing (45x30cm), whereas, spike yield per plot (107.83) and per hectare (2.72 lakh ha-1) were found significantly maximum with optimum spacing (30x30 cm). The large bulb size (>3.0cm) recorded significant increase in all growth and spike parameters and spike yield per hectare. Planting the bulbs at shallow depth (2.5cm) resulted in the early sprouting, flower spike emergence, floret opening and spike girth. The length of spike, number of spikes per plot and hectare and longevity of spike in field increased significantly at deeper depth (6.0 cm). The bigger sized bulbs (more than 3.0 cm) planted at optimum spacing (30x30 cm) and at 6.0 cm depth of planting was found best to get maximum commercial advantage for achieving higher flower yield.
