dc.description.abstractAbstract The present investigation titled “Effect of split application of nitrogen through urea and nano urea on growth and flowering of chrysanthemum under polyhouse conditions” was carried out at Hi-Tech Floriculture Farm of Department of Floriculture and Landscape Architecture, Dr Yashwant Singh Parmar University of Horticulture and Forestry, (Nauni), Solan (HP) during 2022. The experiment was laid out in Randomized Block Design (Factorial) comprising of two cultivars and seven different nutritional modules replicated thrice. The treatment combination comprised of different doses of urea and nano urea applied once a week, twice in a week and once in fortnight starting after pinching and continued up to twelve weeks. Urea was applied as a drench and nano urea as a foliar spray. Maximum plant height (166.65 cm), plant spread (57.64 cm), leaf length (13.36 cm), leaf width (7.73 cm), number of side shoots per plant (5.40), minimum number of days taken for flower bud initiation (120.83 days), minimum days taken to flowering (150.17 days), flower diameter (16.14 cm), number of marketable cut flower stems per plant (5.30), length of cut flower stem (109.85 cm), weight of cut flower stem (138.07 g), number of cut flower stem per meter square (79.50), vase life (26.60 days), duration of flowering (23.09 days), chlorophyll (a) content (66.17 μg/ml), chlorophyll (b) content (25.26 μg/ml) and total chlorophyll content (40.74 μg/ml) was recorded under the application of nutritional module M3 i.e., 100 ppm nano urea once in fortnight starting after pinching and continued up to twelve weeks. The lowest available soil nitrogen (294.94 kg/ha), phosphorus (18.46 kg/ha), potassium (209.83 kg/ha), organic carbon (1.02 %) and EC (0.67) content was recorded under the application of nutritional module M3. The nutritional module M3 had maximum B:C ratio for both the cultivars i.e., ‘White Star’ (4.24) and ‘Yellow Star’ (3.22).
