Abstract Present experiment entitled “Influence of Zinc, Iron and Copper on growth and flowering attributes in gladiolus cv. Sapna” was carried out at Horticultural garden, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the year 2010–11. The observations were recorded on different growth and flowering traits. Randomized block design was used with three replication. Row to row and plant to plant spacing were maintained at 30 x 20 cm, respectively. The experiment consisted two levels each of Zn(Zn0 and Zn1), Fe(Fe0 and Fe1) and Cu(Cu0 and Cu1) which were sprayed on gladiolus plant in three replications. The dose of foliar spray of zinc, iron and copper were 0.5%, 0.25% and 0.25%, respectively. Results revealed that all the vegetative parameters increased significantly by Zn and Cu sprays. Similarly, iron enhanced significantly the height of plant and length only. Combined effect of Zn and Cu increased the height of plant, length of leaves and width of leaves significantly. Whereas, interaction of Zn × Fe and Fe × Cu increased length and width of leaves. Interaction effect of Zn × Fe × Cu also influenced significantly to these attributes. All floral characters influenced significantly by Zn except days to heading. Similarly, Cu increased all floral parameters. Fe also influenced all floral parameters barring the length of spike only. Days to heading significantly increased by Fe × Cu. Top Keywords Zinc, iron, copper, gladiolus, rachis and floret. Top |
