Effect of Different Planting Time on Vegetative and Flowering on Five Cultivar of Gladiolus (Gladiolus grandiflorus L.)

The present study investigates that the effect of three date of planting date 5th October, 20th October, 5th November and cultivars Nova Lux, White Prosperity, Rose Supreme, American Beauty and Big Time Supreme effect on Gladiolus hybrid characters like minimum days taken to sprouting of corms (9.65 days), maximum plant height (77.84 cm), number of leaves (8.70 per plant) were stimulated under 5th November while the characters minimum days taken to spike emergence (68.48 days) and basal florets opening (79.04 days) and maximum length of spike (64.02 cm), number of florets (13.42) per spike, length of florets (11.04), maximum vase life (8.25 days) were stimulates planting on 15th October but maximum duration of spike under field was stimulates planting date 5th October. Among the varieties earliest corm sprouting (10.33 days) and highest vase life (7.87 days) were recorded in cv. Rose Supreme while the cv. American Beauty having largest plant height (84.96 cm), leaves (9.24 per plant), length of spike (74.33), minimum days to basal florets opening (71.07 days), length of florets (11.11 cm) and maximum vase life of spike (9.91 days) were recorded but maximum days required to spike emergence in cv. White Prosperity. Finally concluded that the planting date 15th October to 5th November gave better results with respect vegetative and flowering characters.
