Abstract: The effect of corm size and depth of planting was studied on the growth and flowering of gladiolus cv. Friendship using the combination of four corm sizes (15, 10, 5 and 3 g) and three planting depths planting (10.0, 7.5 and 5.0 cm). Corm size had significant influence on all the parameters studied. Large corm (15 g) took shortest time to complete 80% emergence (15.89 days) and flower initiation (60.44 days). The depth of planting had no marked effect on the parameters studied except percent lodging of plant. The highest lodging of plants (19.83%) was observed in shallowest depth of planting (5.0 cm), and the lowest (7.91%) was found in deepest planting depth (10.0 cm). The combined effect of corm size and depth of planting had significant effect on all the parameters studied except number of spikelets per plant. The highest plant height (97.56 cm), number of leaves (62.33), length of flower stalk (26.07 cm) and lodging of plants (33.14%) in the treatment combination of large sized corm planted at 5.0 cm depth and the lowest in the treatment combination of very small corm with 10 cm depth.
