Effect of foliar spray of micronutrients on yield characters of ixora (Ixora coccinea L.)

Ixora (Ixora coccinea L.) is a perennial shrub belongs to the family Rubiaceae. Micronutrients are essentially as important as macronutrients to have better growth, yield and quality in plants. Quality is one of the important parameter in the floriculture industry which is mainly influenced by application of nutrients. Since the information on the use of micronutrients in ixora is limited and the present investigation was carried out on Ixora coccinea L.. The experiment was carried out at Department of Floriculture and Landscaping, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. Among the treatments, T₄ [FeSO₄ (0.5%) + ZnSO₄ (0.5%)] recorded the highest plant height (75.34, 88.90 and 104.80 cm), maximum plant spread North-South (102.00 cm) and East-West (103.12 cm), highest number of laterals per plant (178.73) and maximum leaf length (6.33 cm) and leaf width (3.54 cm).
