Abstract/ Executive Summary:

Afield experiment was conducted at the Floriculture Research Field, HRC, Bangladesh Agricultural Research Institute, Gazipur from November 2014 to May 2015. The experiment consisted of two factors such as Factor A: corm size (3 levels): small (15.0 - S_I, medium (30.0 g) - S₂ and large (50.0 g) - S₃ and Factor B: boron (four levels) B_o: Control,, 1.0 kg/ha, B₂: 2.0 kg/ha and B₃: 3.0 kg/ha. The results of the experiment showed that the corm size and boron had significant effect on most of the parameters in gladiolus. Maximum flower yield (202000 spikes/ha) was produced from the large sized corm. All doses of baron significantly improved the yield contributing characters of gladiolus over control, while the most effective dose was 2.0 kg/ha boron. However, the treatment combination of large size corm with the application of 2.0 kg/ha boron contributed the best performance in respect of vegetative growth and flowering in gladiolus.

Keywords: Boron, Growth; Flowering; Gladiolus

Location: Floriculture Research Field, HRC, Bangladesh Agricultural Research Institute, Gazipur

Start Date: 00-11-2014

End Date: 00-05-2015

Program Area: Crop-Soil-Water Management

Commodity: Gladiolus, Fertilizer

Objectives:

To determine the optimum corm size and boron level for quality flower production of gladiolus.

Methodology:

The study was undertaken at Floriculture Field of HRC, BARI, Gazipur during 2014-2015 to study the effect of corm size and boron on growth and flowering of gladiolus. BARI Gladiolus-5 used as planting material. The experiment consisted of two factors, which are as follows: Factor A=Corm Size; S₁: Small corm (15.0 g), S₂: Medium corm (30.0 g), S₃: Large corm (50.0 g) and Factor B=Boron Fertilizer; B_o: Control, B₁: 1.0 kg/ha, B₂: 2.0 kg/ha, B₃: 3.0 kg/ha. The experiment was laid out in a Randomized Complete Block Design with three replications. Cultural operations such as weeding, irrigation, disease and pest management etc. were done as and when necessary. Data were recorded on different parameters like plant height, days to spike initiation, spike length, rachis length, number of floret, weight of single spike, flower yield etc. The recorded data were statistically analyzed and treatment means were separated by Duncan's Multiple Range Test (DMRT).

Achievement/Findings:

Corm size and boron had significant effect on most of the parameters of gladiolus. Maximum flower yield was found from the large sized corm and 2.0 kg/ha boron application. So, it can be concluded that large sized corm with 2.0kg/ha boron gave maximum growth and flowering of gladiolus.
