Effect of micronutrients on plant growth, flowering and corm production of gladiolus (Gladiolus grandiflorus L.) cv. White Prosperity

A field experiment was conducted to study the "Effect of different micronutrients on plant growth, flowering and corm production of Gladiolus (Gladiolus grandiflorus L.) cv. White Prosperity. The experiment was conducted in Randomised Block Design where micronutrients were divided into 13 treatments and consisted of either each micronutrients Boron, Zinc and Iron alone with composition (0.1%, 0.2%, 0.3%, 0.4%). The result of experiment revealed that maximum plant height (93.86 cm), number of leaves (7.86 days), number of shoots per plant (2.1), minimum number of days to spike initiation (65.93), number of spikes per plant (1.8), minimum days to opening of first floret (76.13), number of florets per spike (14.53), flower diameter (11.9 cm), number of corms (2.1), shelf life (12) and number of cormels per corm (39) were recorded with treatment T₉ (B 0.4%). The minimum value of growth parameter, floral parameter and yield parameter were recorded with Zinc treatments.
