Effect of Micronutrients (Fe and Zn) on Growth of Chrysanthemum (Chrysanthemum morifolium Ramat.)

The present experiment was conducted on effect of micronutrients (Fe and Zn) on growth, flowering, flower yield and quality of chrysanthemum(Chrysanthemum morifolium Ramat.) cv. IIHR – 6”. Growth was influenced by different levels of ferrous sulphate. The maximum plant height at 60 DAT (56.11 cm) and 90 DAT (72.33 cm), plant spread in N-S (30.67 cm) and E-W (22.67 cm) direction at flower bud initiation stage and in N-S (38.78 cm) and E-W (31.56 cm) direction at full bloom stage, number of primary branches (4.19) and secondary branches (24.89) at full bloom stage, leaf area (37.11 cm²), number of suckers per plant (20.33), fresh weight (306.67 g) and dry weight (35.44 g) of plant were obtained at FeSO₄ @ 0.8 per cent (F₄). In case of different levels of ZnSO₄, the maximum plant height at 60 DAT (53.67 cm) and 90 DAT (70.33 cm), plant spread in N-S (29.75 cm) and E-W (21.83 cm) direction at flower bud initiation stage and in N-S (37.58 cm) and E-W (30.75 cm) direction at full bloom stage, number of primary branches (4.13) and secondary branches (23.00) at full bloom stage, leaf area (35.33 cm²), number of suckers per plant (18.33), fresh weight (297.50 g) and dry weight (33.00 g) of plant were obtained at ZnSO₄ @ 0.5 per cent (Z₃).
