The present study investigates the impact of misting intervals on the growth, physiology, yield, and nutrient uptake of cut chrysanthemum cultivated under an aeroponic system. Two misting treatments—3 minutes on and 5 minutes off (S1), and 2 minutes on and 5 minutes off (S2)—were applied to five chrysanthemum varieties. Significant differences were observed across varieties and treatments for all morphological, physiological, and yield parameters. Among the varieties, V2 consistently outperformed others in plant height (up to 58.34 cm), leaf area index (2.225), flower yield (67.18 flowers/plant), and vase life (16.84 days) under the S2 treatment. Nutrient uptake analysis revealed that V3 and V5 showed superior potassium (up to 3.05%), phosphorus (1.69%), and micronutrient accumulation under S2. Enhanced misting frequency significantly improved root development, chlorophyll content, and enzymatic activity. These findings underscore the potential of optimizing misting intervals in aeroponics to improve floricultural productivity and resource use efficiency.
