Growth and Flowering of Lilium (Lilium longiflorum) cv. Eremo as Affected by CCC and GA\(_3\) under Naturally Ventilated Polyhouse Conditions of Prayagraj

Abstract

The present investigation was carried out under naturally ventilated polyhouse conditions, Department of Horticulture, SHUATS, Prayagraj, during November, 2023 to March, 2024. The experiment was laid out in Randomized Block Design (RBD) with three replications. There were nine treatments comprising of Cycocel (CCC) and Gibberellic Acid (GA3) at different concentrations viz., GA3 (100, 200, 300 and 400 ppm) and CCC (100, 200, 300 and 400 ppm) along with Water spray. The results revealed foliar application of 300 ppm GA3 for Lilium significantly enhanced the number of leaves (71.83), plant height (76.47 cm), plant spread (15.44 cm), leaf area (9.73 cm2),number of buds (3.40),at 300 ppm of GA3 it takes lesser days taken for bud initiation(40.40),and also less days taken for first flower opening from planting (68.53), flower bud length (8.83 cm), flower stalk length (12.43 cm), stalk length (78.10 cm), self-life  (12.97 days),flower yield per plant (3.40) and flower yield for 250 m2(6296.29) . Among the different treatments, the highest Gross return is 188888.7 Rs/250 m2, Net return is 120870.75 Rs/250 m2 and Benefit cost ratio is 2.77, obtained by the application of 300 ppm of GA3.Whereas in terms of only Bulb parameters, foliar application of 200 ppm of CCC for Lilium reported maximum number of bulblets per plant (4.11) and gives maximum weight of bulb per plant (74.07g).
