Effect of planting time on growth, flowering and corm production in gladiolus (Gladiolus hybrida)

An experiment was conducted to find out the effect of different planting dates on vegetating growth, flowering and corm production in gladiolus (Gladiolus hybrida L.) cv. Novalux at Department of Horticulture, Allahabad Agricultural Instistute, Allahabad. Maximum plant height, number of leaves/plant, length of spike, size of floret and duration of spikes in field were recorded under 30th October planting, whereas minimum days to spike initiation and days to basal floret opening were observed with 14th December planting. There were maximum number of corms/plant and weight of corm under 30th October planting, whereas 15th October planting proved beneficial in corm size and weight of cormels/plant.
