Effect of micronutrient formulation on growth and flower yield of annual chrysanthemum

An experimental study was conducted to evaluate the foliar application of PDKV grade II micronutrient at different spraying time on flower yield and quality of annual chrysanthemum at Horticulture Section, College of Agriculture, Nagpur in 2023-24. The experiment was laid out in Factorial Randomized Block Design consisting of twelve treatments replicated thrice. The result of experiment was in respect of growth parameters viz,. plant height was recorded significantly maximum in treatment of PDKV grade II micronutrient concentration 1.5 percent as well as in spraying at 45 DAT. Number of branches plant-1 and plant spread were recorded significantly maximum in treatment of PDKV grade II micronutrient concentration 1.0 percent as well as in spraying at 45 DAT in annual chrysanthemum. For yield parameters i.e. number of flowers plant-1, flower yield plant-1, flower yield plot-1 and hectare-1 were recorded maximum in PDKV grade II micronutrient concentration 1.0 percent as well as in spraying at 45 DAT. The interaction effect of treatment combination of PDKV grade II micronutrient concentration 1.0 percent as well as in spraying at 45 DAT were recorded significantly maximum in number of branches plant-1, number of flowers plant-1, flower yield plant-1, flower yield plot-1 and hectare-1 in annual chrysanthemum.
