EFFECT OF ZINC, IRON AND COPPER ON YIELD PARAMETERS OF GLADIOLUS

An experiment entitled “Effect of zinc, iron and copper on yield parameters in gladiolus” was carried out at, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the year 2010-11. 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. The dose of foliar spray of zinc, iron and cop per were 0.50%, 0.25% and 0.25%, respectively. Weight of corms significantly increased with the application of Zn and Cu (94.38 and 94.82 g, respectively).Diameter of corms influenced significantly with the application of Zn, Fe and Cu (5.71, 5.77 and 5.81 cm diameter, respectively). Foliar spray of Zn, Fe and Cu, significantly increased the number of corms per plant. Interaction between Zn x Fe and Zn x Cu, significantly enhanced number of corms per plant whereas, the number of corms per plant revealed by Zn (1.74),Fe(1.66) and Cu (1.68) over their respective controls. Maximum increase in cormels production per plant was influenced due to application of zinc (44.97) followed by spray of copper (43.18)and iron (42.11) over their respective controls.
