Abstract/ Executive Summary:

The experiment was conducted at the Horticultural Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during the period from October 2, 2012 to January 7, 2013 to find out the influence of GA3 on growth, yield and yield contributing characters of broccoli (Brassica oleracea var. Italica). The experiment was conducted using Randomized Complete Block Design (RCBD) with three replications. Four levels of GA₃ viz. C₁: Control, C₂: 25 ppm GA₃, C₃: 50 ppm GA₃ and C₄: 75 ppm GA₃ was used on the experiment. The maximum plant height (31.5 cm), number of leaves (16.6/plant), number of main fingers (12.0/main curd), main curd length (21.3 cm), main curd diameter (19.3 cm), main curd weight (668.0 g/plant) and yield (24.5 t/ha) was found from the application of 50 ppm GA₃, while the minimum from control. It was revealed that, 50 ppm GA₃ gave maximum yield/ha (24.5 tons). From the study it was also found that application of more than 50 ppm GA₃ reduced the yield of broccoli.

Keywords: Broccoli, GA3, Yield

Location: Horticultural Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur

Start Date: 02-10-2012

End Date: 07-01-2013

Program Area: Crop-Soil-Water Management

Commodity: Broccoli

Objectives:

To find out the influence of GA₃ on growth, yield and yield contributing characters of broccoli.

Methodology:

The experiment was conducted at the Horticultural Research Farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during the period from October 2, 2012 to January 7, 2013 using Randomized Complete Block Design (RCBD) with three replications. Four levels of GA viz. C₁ : Control, C₂ : 25 ppm GA , C₃ : 50 ppm GA3 and C₄: 75 ppm GA3 was used in the experiment. The unit plot area was 1.5 m x 2.0 m having plot to plot and replication to replication distance of 0.5 and 1.0 m, respectively. There were four rows in each plot having three plants per row and 12 plants were accumulated in each plot. Row to row and plant to plant distance was 50 cm and 50 cm, respectively. Data were collected on plant height, number of leaves per plant, leaf size, canopy spread, stem diameter, plant vigor, days to curd initiation (1^stand 50%), main curd diameter, main curd length, main curd weight/plant, yield/plant and yield. The collected data on various parameters were statistically analyzed using MSTAT-C program. The means were separated by Duncan's Multiple Range Test (DMRT) at 5% level of probability.
