Various Fertilization Managements Influence the Flowering Attributes, Yield Response, Biochemical Activity and SoilNutrient Status of Chrysanthemum (Chrysanthemum morifolium Ramat.)

Optimal nutrient management is critical for optimizing flowering, yield, quality and improving soil health. A key approach making chrysanthemum crop cultivation profitable balanced fertigation at the right time. This possible by through drip. The present study was designed in 2019–2021 a model floriculture center, Pantnagar, to investigate response of split application NPK drip on flowering attributes, biochemical activity status chrysanthemum. Plants received with five treatment combinations: T1-NPK @ 100:150:100 kg/ha/year, T2-NPK T3-NPK T4-NPK 75:112.5:75 kg/ha/year T5-NPK vegetative, bud stages. results reveal that plants treated T3 (NPK kg/ha/year) exhibited maximum increases floral diameter (31.45%), number inflorescences per branch (24.44%), inflorescence (15.32–28.44%), weight (24.30%), stem diameter, length, plant (6.16%), hectare (53.46%), chlorophyll content, b total content (40.20%), carotene (69.56%), organic carbon (1.22-fold), available nitrogen (7.46%), phosphorus potassium (1.14-fold) compared control. Conclusively, suggest may improve
