Abstract:
The present investigation entitled “Effect of foliar application of zinc and iron on growth, flowering and yield of gladiolus (Gladiolus grandiflorus L.)” was carried out during the year of 2020-21 in rabi season i.e. from November - April, at Department of Floriculture and Landscape Architecture, Pt. Kishori Lal Shukla College of Horticulture and Research Station, Rajnandgaon (C.G.). The micro-nutrient used were T₁ control (water spray), T₂ zinc 0.3%, T₃ zinc 0.6%, T₄ zinc 0.9%, T₅ iron 0.3%, T₆ iron 0.6%, T₇ 0.9%, T₈ zinc 0.3% + iron 0.3%, T₉ zinc 0.6% + iron 0.6%, T₁₀ zinc 0.9% + iron 0.9% and T₁₁ zinc 0.9% + iron 0.3%. The experimental results revealed that the minimum number of days taken for spike initiation (68.07 days), maximum length of spike (88.37cm), maximum length of rachis (54.31cm), higher number of florets (13.93), more longevity of flower (11.40 days) and maximum vase life of cut flower (11.53 days) was found in foliar application of 0.3% zinc + 0.3% iron (T₈).
