Abstract/ Executive Summary:

An experiment was conducted at Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh from November, 2011 to June, 2012 to find the out better level of zinc on growth, flowering and production of corms and cormels of gladiolus. Experiment consisted four different levels of zinc viz. Z₀= 0 kg Zn/ha, Z₁= 1 kg Zn/ha (1.28 Kg ZnO), Z₂= 2 kg Zn/ha (2.56 Kg ZnO), Z₃= 3 kg Zn/ha (3.84 Kg ZnO) and Z₄= 4 kg Zn/ha (5.12 Kg ZnO). Maximum number of spike (22.3/plot), number of floret/spike (16.1), corm yield (1.23 kg/plot) and cormel yield (1.06 kg/plot) was found from Z₃ while lowest number of spike (17.9/plot), number of floret/spike (11.1), corm yield (0.86 kg/plot) and cormel yield (0.80 kg/plot) was found from Z₀.

Keywords: Gladiolus, Zinc, Flowering, Corm-cormel yield.

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

Start Date: 00-11-2011

End Date: 00-06-2012

Program Area: Crop-Soil-Water Management

Commodity: Gladiolus

Objectives:

To find out the better level of zinc for ensuring higher yield of gladiolus.

Methodology:

A field experiment was conducted at Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh from November, 2011 to June, 2012 to find the out better level of zinc on growth, flowering and yield of gladiolus. Experiment consisted four levels of zinc viz. Z₀= 0 kg Zn/ha (Control), Z₁= 1 kg Zn/ha (1.28 Kg ZnO), Z₂= 2 kg Zn/ha (2.56 Kg ZnO), Z₃= 3 kg Zn/ha (3.84 Kg ZnO) and Z₄= 4 kg Zn/ha (5.12 Kg ZnO) following Randomized Complete Block Design with three replications. 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. The entire amounts of cowdung (10 t/ha), TSP (200 kg/ha) and MP (200 kg/ha) were applied during the final land preparation. Urea (200 kg/ha) was applied in three equal installments at 15, 30 and 45 days after planting (BARI, 2005). 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 Ducan’s Multiple Range Test (DMRT) at 5% level of probability.

Achievement/Findings:

Finally it can be concluded that 3 kg Zn/ha (3.84 Kg ZnO) was the best among different zinc levels in terms of maximum growth, flowering and production of corms and cormels.
