​Effect of Different Growing Conditions and Genotypes on Growth and Bulb Parameters of Asiatic Lily

Background: The present investigation was carried out during the cropping season of year 2019-20 to find out the most suitable growing condition as well as variety of Asiatic lily for the production of bulbs/bulblets under Hisar (Haryana) conditions.
Methods: The experiment was laid out in RBD (factorial) with three replications and twelve treatment combinations, comprising of three growing conditions (polyhouse of 200 µ, green shade-net of 50% shade and open field) and four varieties (Courier White, Tresor, Nova Lux and Red Stone).
Result: These varieties of Asiatic lily when grown under polyhouse performed better in some parameters resulting in early bulb sprouting, maximum plant height and number of leaves/plant and the minimum days upto harvesting of bulbs, however, in other parameters viz. leaf length and width, weight of bulbs/plant, diameter of bulb and number of bulblets/plant, the shade-net condition was observed to be better than polyhouse. Overall, Tresor performed better, resulting in early bulb sprouting (5.11 days), minimum days (236.56) upto harvesting of bulbs and the maximum plant height (89.01 cm), number of leaves/plant (64.08), leaf length (9.50 cm), diameter of bulb (3.91 cm) and number of bulblets/plant (2.99) and it was followed by Red Stone which produced maximum weight of bulbs/plant (59.03 g) and observed next to Tresor in most of the parameters. Tresor grown under polyhouse took minimum days (231) upto the harvesting of bulbs, produced maximum plant height (115.13 cm) and number of leaves/plant (69.67) and it was closely followed by Red Stone grown under same condition. Further, under the shade-net, Red Stone produced maximum weight of bulbs/plant (65.30 g) followed by Tresor (63.93 g), while the maximum number of bulblets/plant (3.90) were produced by Tresor followed by Red Stone (3.44). Henceforth, Tresor and Red Stone when grown under polyhouse performed better in vegetative parameters and when grown under shade-net performed better in bulb parameters than the other combinations of growing conditions and varieties.
