The experiment was conducted at the research field of the Department of Horticulture, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur from November 2017 to May 2018. Nineteen gladiolus germplasm were previously collected from farmer’s field and nurseries of Godkhali, Benapole, Jessore, Bogra, Savar areas through direct visit and were included in the experiment. Cut flower stick of all collected germplasm are presented in Plate 1 and 2. The germplasm were numbered as G1, G2, G3, G4, G5, G6, G7, G8, G9, G10, G11, G12, G13, G14, G15, G16, G17, G18 and G19. Out of these germplasm, G1, G4, G7 and G12 has already been released by the Bangladesh Agricultural Research Institute as BARI gladiolus- 3, BARI gladiolus- 5, BARI gladiolus- 6 and BARI gladiolus- 1, respectively. The unit plot size was 1.2 m X 1.2 m. Medium sized (3.5-4.5 cm) corms of different gladiolus germplasm were planted at about 6-9 cm depth in the plot maintaining a spacing of 30 cm X 15 cm. The experiment was set up on November 12, 2017 following Randomized Complete Block Design (RCBD) with 3 replications. Manures and fertilizers were applied at the rate of cowdung- 10 t/ha, Urea- 300 kg/ha, TSP- 375 kg/ha, MoP- 300 kg/ha, Boric acid- 12.0 kg/ha and Zinc sulphate- 8.0 kg/ha (Azad, 2017). Entire quantity of manures and fertilizers except urea were applied during final land preparation and mixed with soil. Half of urea was top dressed after 25 days of planting and rest half was applied during spike initiation stage. Different intercultural operations like irrigation, weeding, earthing up, stacking, pesticide and fungicide application were performed as needed. The spikes were cut when lower one or two florets showed color but still in tight bud stage. The cut spikes were kept into water to study the vase life. Corms and cormel were harvested only when the leaves turned into brown colour (Mukhopadhyay, 1995). The collected data were statistically analyzed using computer MSTAT-C program. Mean separation was done by Duncan’s Multiple Range Test (DMRT).
