Abstract:
The experiment entitled “Effect of plant spacing and nitrogen schedule on growth and quality of Asiatic lily (Lilium × asiatica) cv. Litouwen under naturally ventilated polyhouse conditions of Prayagraj”, was carried out under Prayagraj agro-climatic condition in the Department of Horticulture, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the month of December 2020 to March 2021. The experiment was laid out in Factorial Randomized Block Design with three replications and twelve treatment combinations. Treatments comprised of three different spacing (15 cm x 20 cm, 20 cm x 20 cm and 25 cm x 20 cm) and recommended dose of CAN (Calcium ammonium nitrate) was applied as foliar spray in splits. The results revealed that the spacing S₁ (15 cm x 20 cm) resulted better in vegetative growth (Plant height and stalk length) and flowering parameter (bud diameter) whereas spacing S₃ (25 cm x 20 cm) resulted in better vegetative growth (Number of leaves, plant spread and total chlorophyll content) and floral parameters (Bud emergence, number of buds, flower diameter, stalk diameter, vase life and number of bulblets). Among nitrogen schedule, nitrogen schedule N₄ (Foliar application of CAN thrice a week) gave better result in vegetative growth (plant height, number of leaves, plant spread and chlorophyll content) and floral parameters (bud emergence, number of buds, bud diameter, flower diameter, stalk length, stalk diameter, vase life and number of bulblets). The best interaction among the different spacing and nitrogen schedule was found to be spacing S₃ (25 cm x 20 cm) and nitrogen schedule N₄ (Foliar application of CAN thrice a week) which gave maximum growth and qualitative characteristics of Asiatic lily.
