Abstract:
An experiment entitled “Effect of corm size on growth and yield parameters in gladiolus (Gladiolus grandiflorus L.) cv. White Prosperity” was conducted during Rabi-Summer season of the year 2022-23 at College of Horticulture, Dapoli, Dist. Ratnagiri, (Maharashtra state). The experiment was laid out in Randomized Block Design with four replications and five treatments i.e., T₁-Below 10 g, T₂-11-20 g, T₃-21-30 g, T₄-31-40 g and T₅-41-50 g. The results revealed that minimum number of days required for first sprouting (7.65) and 50 percent sprouting of corms (11.60), highest plant height (143.75 cm), leaf area (81.63 cm²), minimum days to first spike emergence (65.10), days to 50 percent spike emergence (71.03), maximum number of spikes per hectare (1.74 lacs), number of corms per hectare (1.70 lacs) and number of cormels per hectare (31.73 lacs) were recorded in treatment T₅-41-50 g. Thus, it could be observed from the results that, the corm size 41-50 g of gladiolus cv. White prosperity was found to give higher yield in respect of number of spikes, corms and cormels produced per plant.
