Bioregulation of foliar application of micronutrients on the growth and yield of marigold (Tagetis erecta L.) cv. African Giant

Yield attributing characters except the leaf area index (LAI) were significantly influenced by the various micronutrient treatments. Among the different treatments, ZnSO₄, 7H₂O; CuSO₄, 5H₂O + ZnSO₄, 7H₂O and Chelamin produced more pronounced effect on these characters. The highest flower yield was obtained under the treatment of mobomin. Correlation between flower yield and yield attributes indicated that there existed a highly positive and significant correlation between flower yield and yield attributes except leaf area constant which had negative and highly significant correlations with flower yield.
