Abstract:
Gladiolus is a commercially important cut flower in many countries. However, scientific research on its cultivation under the climatic conditions of Bangladesh is quite limited, representing a significant research gap. To address this, a two-factor experiment (planting depth and spacing) was completed by a Randomized Complete Block Design (RCBD) where three replications were available. Each factors contained 3 levels namely spacing 1 (25 cm x 10 cm, S1), spacing 2 (25 cm x 15 cm, S2) and spacing 3 (25 cm x 20 cm, S3), depth 1 (5 cm, D1), depth 2 (7 cm, D2 and depth 3 (9 cm, D3). Three blocks were divided into 9 plots. The plot size was 120 cm x 100 cm. The plot-plot spacing was 50 cm in both sides. The widest spacing ensured tallest plant (54.49 cm), maximum number of leaves (8.90), tallest spike (85.68 cm), maximum weight of individual corm (44.39 gm) per plant, whereas maximum yield of spike (11.40 t/ha) and corm (7.99 t/ha) was obtained from the closest spacing. Similarly the shallowest depth of planting produced maximum weight (6.54 t/ha) and number of cormel (38.43 / plant) whereas the deepest depth produced tallest (82.56 cm) and heaviest (8.71 t/h) spike. Combination of S1 and D3 produced the maximum yield of spike (12 t/h) but S1 combine with D1 produced the highest yield of corm (8.29 t/ha).
