Abstract/ Executive Summary:

An experiment was conducted at Horticulture farm, Sher-e-Bangla Agricultural University, Bangladesh to evaluate the effect of corm size on growth and flowering of gladiolus. Experiment consisted three different sized corm viz. C₁= Small size corm (11-20 g); C₂= Medium size corm (21-30 g); C₃= Large size corm (31-40 g). Maximum number of leaves (11.3), number of floret/spike (15.9), spike/plot (21.8), tallest plant (76.3 cm), longest flower stalk (69.3 cm) and rachis (36.3 cm) at harvest were found from C₃. Maximum corm (7.0 cm, 25.1 g, 2.3 cm and 1.2 kg for thickness, weight, diameter and yield/plot respectively) and cormel (25.3, 14.6 g, 1.5 cm and 1.1 kg for number/plant, weight, diameter and yield/plot respectively) production was found from C₃ whereas minimum from C₁.

Keywords: Gladiolus, Growth, Flowering and Yield

Location: Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh.

Start Date: 00-11-2011

End Date: 00-06-2012

Program Area: Seed Technology

Commodity: Gladiolus

Objectives:

To find out the suitable corm size for growth, flowering and yield of gladiolus.

Methodology:

A field experiment was conducted at the Horticulture Farm, Sher-e-Bangl a Agricultural University, Dhaka , Bangladesh from November, 2011 to June, 2012 to find out the effect of corm size on growth, flowering and yield of gladiolus. Experiment consisted three different corm size viz. C₁= Small size corm (11-20 g); C₂= Medium size corm (21-30 g); C₃= Large size corm (31-40 g) following Randomized Complete Block Design with three replications. Yellow colored gladiolus was used on the experiment. The unit plot size was 1 m × 0.75 m. The corm was planted into the soil maintaining row to row distance at 25 cm and plant to plant distance at 20 cm. There were 15 plants containing in each plot. Cowdung (10 t/ha), urea (200 kg/ha), TSP (200 kg/ha) and MP (200 kg/ha) were applied. The entire amounts of cowdung, TSP and MP were applied during the final land preparation. Urea was applied in three equal installments at 15, 30 and 45 days after planting. Five plants were randomly selected from middle of the each unit of plot for data collection. Collected data were statistically analyzed using MSTAT-C computer package program and mean was calculated. The significance of the difference among the treatment combinations means was estimated by the Ducan’s Multiple Range Test (DMRT) at 5% level of probability.
