Integrated Nutrient Managemen For Improving Plant Growth, Flowering And Bulb Production In Hyacinthcv. Yellow Stone

Abstract

The present investigation entitled “Integrated Nutrient Management for improving plant growth, flowering and bulb production in Hyacinth (Hyacinthus orientalis) cv. Yellow Stone” was carried out at the Floriculture experimental field SKUAST-K during the year 2018-19. Biofertilizers were applied to the bulbs at planting time using the dip method followed by shade drying before planting. The experiment was laid out in Randomized Complete Block Design with 15 treatments replicated three times. The results of the study revealed that the treatment T15 significantly improved vegetative, floral, and bulb characteristics. Treatment combination containing 80% RFD + Vermicompost (12 tons ha-1) + Biofertilizers (PSB + KSB +Azotobacter) resulted in a minimum number of days taken to bulb sprouting (75.83days), first leaf appearance (81.50days), second leaf appearance (83.50days), third leaf appearance (85.33days), bud appearance (88.33 days) , color break (99.58days), complete flower formation(109.83days), maximum plant height (18.40cm), leaf length (13.87cm), leaf width (2.45cm), length of a spike (18.06cm), Spike thickness (7.90mm), number of leaves per plant (23.83), number of florets per spike (20.33), the diameter of inflorescence (7.06cm), length of inflorescence (7.10cm), duration of flowering (18.33days), bulb weight (40.22g), bulb size(11.52cm), number of offsets per bulb (3.83), weight of offsets per bulb (20.17g).
