Online Published on 15 December, 2023. Abstract The investigations were carried out for two consecutive seasons during the year 2018-19 at research Farm, PAU, Ludhiana with the purpose of evaluating the influence of various levels of nitrogen on growth and flowering of chrysanthemum cultivar ‘White Star’. Different levels of nitrogen N @ (10, 15 and 20 g m-2) along with 0 (control) were used. The results revealed that the highest plant height and chlorophyll content were recorded in the treatment where nitrogen was applied @ 20 g m-2 whereas, the earliness in bud appearance, maximum number of flowers per stem, weight of cut flowers, stem and flower diameter, leaf area and longest vase life were observed in the plants fertilized with nitrogen @ 10 g m-2. The optimum dose of nitrogen for improvement of most of the vegetative and floral characters was 10 g m-2 and that can be recommended as economic dose for commercial cut flower production of chrysanthemum.
