The laboratory experiment was laid out in a completely randomized design with ten treatments in four replications. The seeds of stevia were treated with different seed treatments for assessment of seed quality parameters. The seeds soaked in GA3 at 10 ppm for 12 hours had recorded early commencement of seed germination (3.00 days), maximum germination per cent (62.25%), root length (10.30 mm), shoot length (14.15 mm), seedling vigour index (1522), seedling dry weight (2.90 mg per 10 seedlings) and field emergence (47.75%) compared to other treatments. The propagation experiment in shade house was laid out in a completely randomized design with ten treatments in three replications. The cuttings treated with IBA at 500 ppm took minimum number of days to sprouting (12.68 days) and it showed maximum number of leaves (45.84), shoot length (33.56 cm), root length (16.63 cm), fresh weight of leaves and root (1.503 g and 0.903 g) and dry weight of leaves and root (0.460 g and 0.357 g) respectively, at 45 days after planting. Field experiment on response of growth regulators on growth, herbage yield and quality in stevia was laid out in a randomized complete block design with ten treatments and three replications. The IBA at 500 ppm treated cuttings showed maximum plant height (38.75 cm), number of leaves per plant (476.86), number of branches per plant (31.19), plant spread (27.82 cm2 ), highest fresh (7.34 t) and dry (2.03 t) herbage yield per hectare at harvest, IBA at 750 ppm showed maximum stevioside per cent (2.59%) and stevioside yield (51.04 kg/ha) compared to all other treatments.EnglishThesis
