Abstract
The present Research was conducted To evaluate the response of lilium by GA3, IAA and Ethrel to analyse the growth and yield under polyhouse in Prayagraj agro climatic condition. The experiment was layout in Randomized block design (RBD) with 13 treatments and each treatment replicated thrice. The experiment was carried out during November, 2021 to February, 2022 in Research Field, Department of Horticulture, SHUATS, Prayagraj. The treatments consist of different concentrations of plant growth regulators (IAA, Ethrel and GA3). From the experimental findings, it was found that the treatment T10 (GA3@200ppm) was found the superior compared to other treatment combination, which recorded highest plant height (71.36 cm), Number of leaves (72.36), plant spread (15.44 cm2), Earliness in first flower bud initiation (44.33 days), Earliness first flower initiation (50.07 days), flower stalk diameter (6.55 mm), number of buds per inflorescence (4.66), Bud length (11.59 cm), Bud diameter (17.07 mm), Flower diameter (16.26 mm), Vase life (10.55 days), Number of spike yield per plant (2.23), number of spike yield per hectare (77142.59).The present research shows that the treatment of (GA3@200ppm) resulted best among remaining Treatment concentations under the Prayagraj agro climatic condition.
