The Chrysanthemum (Chrysanthemum morifolium) is one of the four most popular cut flowers in the world and renowned for its enormous aesthetic appeal. The vegetative growth of Chrysanthemum plants is influenced by enormous factors, among which nutrient intake performs a crucial role. In this experiment, we investigate the individual effects of four essential nutrients – Boron (B), Calcium (Ca), Magnesium (Mg), and Iron (Fe) – on Chrysanthemum vegetative growth. The experimental design followed a Randomized Complete Block Design (RCBD), comprising three replications, with each replication accommodating three plants per treatment. The foliar application of micronutrients was executed for vegetative growth of chrysanthemums as follows: T 0 = Control, T 1 = 0.2g/ml of Boron, T 2 = 0.2g/ml of Calcium, T 3 = 0.1g/ml of Magnesium, T 4 = 0.2g/ml of Iron. The results demonstrate that the maximum plant height (42.43cm) was recorded in T 3 = 0.1g/ml of Magnesium, the maximum leaf width (4.13 cm) was recorded on T 3 = 0.1g/ml of Magnesium, the maximum number (15.70) of leave plant -1 was observed in T 2 = 0.2g/ml of Calcium while the maximum number (3.34) of branches plant -1 was observed in T 3 = 0.1g/ml of Magnesium. This research focused on limited nutrient treatments on vegetative growth, but further research should explore a wider range to determine optimal chrysanthemum growth treatments. Furthermore, this research lays the foundation for understanding the importance of micronutrient management in the vegetative growth of Chrysanthemum, a significant ornamental crop.
