Abstract:
An experiment was undertaken at the Indra Gandhi Memorial Tulip Garden, Directorate of Floriculture, Government of Jammu and Kashmir during the year 2016-17 and 2017-18, withtwo cultivars (Blushing lady & Ile-de-france) and seven nutrient sprays i.e.N₁ (Distilled water), N₂ (NPK:19-19-19 @ 2g L^-1), N₃ (NPK:19-19-19 @ 4g L^-1), N₄ (NPK:19-19-19 @ 6g L^-1), N₅ (NPK: 19-19-19 @ 2g L^-1+Calimax gold @1.0 ml L^-1), N₆ (NPK : 19-19-19 @ 4g L^-1+Calimax gold @ 1.0 ml L^-1), N₇ (NPK: 19-19-19 @ 6g L^-1+Calimax gold @ 1.0 ml L^-1). All the treatments were replicated thrice under split plot design. Cultivar had a significant effect on all flowering parameters. Early flower bud appearance (37.19 day), flower bud length (6.84 cm), flower bud circumference (6.71 cm), colour break (8.39 day), flower opening (4.81 day), flower diameter (9.41 cm), scape length (40.43 cm), scape thickness (32.30 mm), flowering duration (17.38 day), were recorded with cv. Blushing lady while leaf chlorophyll content (47.35 SPAD), bulblet number/plant (2.61), weight of bulblets/plant (9.28 g) and propagation coefficient (241.64%) were maximum in cv. Ile-de-france. Nutrient spays had a positive influence on growth parameters. Combined application of macronutrients (NPK: 19-19-19) and micronutrients (Calimax gold) was more effective than macronutrients alone. Maximum flower bud length (6.92 cm), flower bud circumference (7.14 cm), flower diameter (9.14 cm), scape length (41.36 cm), scape thickness (33.47 mm), flowering duration (17.29 day), bulb number/plant (1.33), weight of main bulb (25.00 g) and size of main bulb (12.62 cm), bulblet number/plant (2.83), weight of bulblets/plant (10.36 g) and propagation coefficient (242.24%) were recorded with the application of N7 (NPK:19-19-19 @ 6g L^-1+Calimax gold @ 1.0 ml L^-1) and minimum values for all these parameter were recorded in treatment N1 (Distilled water).. However, days to flower bud appearance (34.12), colour break (8.01 day) and flower opening (4.46 day) were maximum with N₅ (NPK:19-19-19 @ 2g L^-1+Calimax gold @1.0 ml L^-1).
