Abstract
An experiment was carried out in Floriculture section, at Regional Horticultural Research and Extension Centre, UHS campus, Bengaluru during 2015-16. Experiment was laid out in Factorial Randomized Complete Block Design (FRCBD) comprising of four levels of fertigation (200:100:250 kg NPK/ha through soil application, 150:75:187.5, 200:100:250 and 250:125:312.5 kg NPK/ha through fertigation) and two varieties (Tropical and Xavia) of anthurium. Results revealed that, application of 250:125:312.5 kg NPK per hectare at 15 days interval through fertigation resulted in increased plant height (109.88 cm), number of leaves per plant (10.41), leaf length (51.91 cm), leaf width (33.11 cm), leaf area (1459.69 cm2), number of suckers (1.98), stalk length (68.20 cm), stalk diameter (7.60 mm), spathe length (18.33 cm), spathe width (12.61 cm), number of flowers per plant per year (8.75), first grade flowers (71.81%), vase life (28.33 days) and also B:C ratio (2.26), whereas it was minimum in control. Among the varieties, maximum plant height (104.42 cm), leaf width (31.24 cm), leaf area (1262.89 cm2), number of suckers (1.18), stalk length (64.46 cm), stalk diameter (7.52 mm), spathe length (18.24 cm) and vase life (28.83 days) was recorded in cv. Xavia. Whereas, highest number of leaves per plant (10.01), leaf length (50.01 cm), spathe width (12.12 cm) and flower yield (7.63) was recorded in cv. Tropical. Regarding the season is concerned, winter season was found to be ideal with respect to high yield and quality of flower production.
