Description The present investigation entitled "Effect of phenophase based application of nitrogen, phosphorous and potassium on chrysanthemum (Chrysanthemum morifolium Ramat)" was carried out at Research Farm of Department of Floriculture and Landscape Architecture, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan-173 230 (H.P.) during the year 2019-2020 to find out the effect of phenophase based application of N, P and K for production of quality flowers in chrysanthemum. Two cultivars with five treatments consisting of N, P and K were applied through basal dose as well as drench method at different growth phases i.e. vegetative, bud and flowering phase. The field experiment was laid out in a Randomized Block Design (RBD) with three replications. The outcome of study revealed that maximum plant height (57.87 cm), plant spread (27.55 cm), minimum number of days for flower bud appearance (97.92 days) and minimum days to flowering (140.91 days) were recorded in plants which received treatment T4 {40:20:20% NPK (Vegetative phase), 30:40:40% NPK (Bud phase), 30:40:40% (Flowering phase) @ 75:112.5:75 kg NPK/ha}. While, flower diameter (8.53 cm), number of shoots per plant (3.72), weight of flowers per plant (50.01 g), duration of flowering (25.77 days) and number of suckers produced per plant (15.33) were recorded maximum in T5 {33.3:33.3:33.3% NPK (Vegetative phase), 33.3:33.3:33.3% NPK (Bud phase), 33.3:33.3:33.3% NPK (Flowering phase) @ 100:150:100 kg NPK/ha}.
