Study the effect of light condition and height of flower harvesting on bulb and bulblet production of Asiatic hybrid lily

摘要

The present investigations entitled “Study the effect of light condition and height of flower harvesting on bulb and bulblet production of Asiatic hybrid lily” was carried out in the Research Farm of Division of Floriculture, CSIR-Institute of Himalayan Bioresource Technology, Palampur, Kangra, Himachal Pradesh during 2012-13 and 2013-14. The treatments consistence of four shade net condition i.e. 30% green shade net (G_1), 50% green shade net (G, 75% green shade net (G_3) and open field condition(Control) (GJ in main plot, four height of flower harvest i.e. 15 cm above ground (H_1), 30 cm above ground (H_2), 45 cm above ground (H_3 and no flower harvest (H_4) in sub plot and three cultivar i.e. Gran Paradiso (V_1), Novecento (V_2) and Adelina (V_3) in sub-sub plot treatments were laid out in split-split plot design with three replications. Comparison was made for the treatments of the crop characters related to number of bulb and bulblet production, circumference (cm) and weight characters. Results revealed that green shade net significantly influenced the bulb and bulblet production and found highest number of bulbs and bulblet per plant with 50% green shade net whereas least number of bulbs was found with open field conditions. No harvestingof the flower produced more number of bulb and bulblet production. Among varieties Gran Paradiso produced more number of bulbs and bulblet per plant while minimum number of bulbs per plant was observed by Novecento. Highest bulb circumference (cm) of bulb and bulblet was found with 50% green shade net condition. The maximum bulb circumference was found in no flower harvesting treatment and minimum with 15 cm above ground. The cultivar Gran Paradiso noted maximum bulb and bulblet circumference (cm). Further results indicated that 50% green shade net gave maximum weight of bulbs and bulblet per plant. With regard flower harvesting treatment, maximum weight of bulbs and bulblet per plant per plant was observed with no flower harvesting treatment. Among cultivar, Gran Paradiso produced highest weight of bulbs per plant while cultivar Novecento produced minimum bulbs weight per plant.
