Effect of horticultural techniques on corm and cormel production of Gladiolus grandiflorus cv. PDKV gold


Author(s): Patil Uday H, SR Dalal and Gaidhani AH

Abstract: The investigation entitled “Effect of horticultural techniques on corm and cormel production of Gladiolus grandiflorus cv. PDKV Gold” was carried out during kharif season of the year 2017-18 and 2018-19 at Floriculture unit, Department of Horticulture, Dr. PDKV., Akola. Vegetative, flowering and yield i.e. corm characteristics of gladiolus as affected by different horticultural techniques such as four different corm sizes, jumbo size corm (> 5.1 cm), large sized corm (3.8 to 5.0 cm), medium (3.2 to 3.7 cm), small size corm (3.1 to 2.5 cm) mechanical removal of apical bud (3.8 to 3.2 cm), half corm division (3.2 to 3.7 cm), soaking of corms in 200 ppm GA3 solution for 24 hr (3.2 - 3.7 cm) and clipping of leaves (3.2 to 3.7 cm) were evaluated under natural agro-climatic conditions of Akola. The experiment was laid out in accordance with Complete Randomized Design with eight treatments replicated three times. Regarding growth parameters it was observed that days required for sprouting of corm, number of shoots per corm, plant height, number of leaves per plant, (at 30, 60, 90 and 120 DAP) length and breadth of leaves, jumbo size corm perform the best as compared to medium and small corms with maximum values (3.93 days), (2.03), (49.10, 91.63, 111.27 and 113.10 cm), (3.33, 6.13, 8.87 and 9.33 cm), (85.55 and 2.82 cm). Similar results were observed with flowering and yield parameters. In flowering parameter such as minimum days for spike emergence, days to 1st floret opening, days to 50% flowering (77.78, 82.08, 87.13 days respectively) and maximum number of spikes plant-1 (1.67) and ha-1 (1.48 lakh) was recorded in jumbo size corm than large and small size corm. Regarding yield parameter maximum number of corms and cormels plant-1(2.23, 19) and ha-1 (2.48, 21.11 lakh), weight of single corm (54.67 g), weight of corms plant-1 (106.85 g) ha-1 (117.93 q) and diameter of corm (6.41 cm) was recorded in jumbo size corm. In case of quality parameter maximum length of spike, diameter of spike, length of rachis, number of florets spike-1 diameter of open floret and vase life of spike was observed by plants raised from jumbo sized corm.
