Abstract: An investigation was carried out at the Horticultural Research Farm Department of Horticulture, Banaras Hindu University, Varanasi, 221005 (Uttar Pradesh) during the year 2016-17 to standardize the combination of optimum corm sized and spacing for the production of gladiolus with better flowering and post-harvest potentials. The investigation was laid out factorial randomized block design with three replications. The data on various flowering and post-harvest parameters recorded from 5 randomly selected plants from each treatment in each replication. The treatment comprises nine combination with three corm sizes viz. C₁ (2-3 cm), C₂ (3.1-4 cm) and C₃ (4.1-5 cm) and three spacing S₁ (30 × 20 cm), S₂ (30 × 25 cm) and S₃ (30 × 30 cm). Results revealed that combination effect of 4.1-5.0 cm corn size and 30 × 30 cm spacing result maximum number of florets per spike (15.6), diameter of 1^st floret (9.2 cm), diameter of 3^rd floret (9.0 cm), diameter of 5^th floret (8.8 cm), length of spike at colour show (49.4 cm), 1^st floret opening (57.7 cm), length of spike at last floret opening (68.6 cm), percentage of florets opened in vase (88.5), vase life (18.0 days), floret longevity (8.0 days) and length of spike after post-harvest (67.0 cm) also provide minimum days taken to initiation of spike (66.8 days), days taken to colour show (74.0 days) and days taken to opening of 1^st floret (78.5 days). On contrary the combination effect of 2-3cm corm size and 30×25 cm showed prominent result in terms of highest (9.8 days) days for 1^st sprouting, durability of 2^nd floret (6.5 days), durability of 3^rd floret (6.6 days) and days taken to last floret withering (110.03 days).
