Abstract/ Executive Summary:

The experiment was conducted with two advanced cauliflower lines with one check variety (BARI Fulcopi 1 and Maradona) at four locations of BARI which included Joydebpur, Hathazari, Jessore and Comilla during the season 2014-2015 to observe the performance of advanced cauliflower lines at early winter season. In average of four locations, the line CL-0171 and CL-0172 required (74.8 and 70.75days) and local check Maradona required 71 days to curd harvest while BARI Fulcopi-1 failed to curd production. Among the two advanced lines, CL-0172 produced heaviest marketable curd (352.3 g), while the line CL-0171 (288.5g) and Maradona produced (586.7g) marketable curd weight. The highest calculative per hectare yield (11.64 t) was recorded from the line CL-0172 and the line CL-0171produced (9.78t) while check variety Maradona produced (23.47t). Considering the overall performance the advanced line CL-0172 is being proposed to release as an early Op cauliflower variety.

Location: Joydebpur, Hathazari, Jessore and Comilla

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Variety and Species

Commodity: Cauliflower

Objectives:

To observe the performance of advanced cauliflower lines in early winter season.

Methodology:

The experiment was conducted at four locations of Bangladesh Agriculture Research Institute, which included Joydebpur, Hathazari, Jessore and Comilla during July to November, 2014. The experiment was laid out in RCB design with three replications. Seeds of two advanced lines (CL- 0171, CL- 0172) and local check (BARI Fulcopi-1 and Maradona) were sown on 15-18 July, 2014 in seedbed.Thirty days old seedlings were transplanted in main field. Seedlings were spaced at 60x40 cm, between plant-to-plant and row-to-row, respectively. The land was fertilized with cowdung-urea-TSP-MoP-boron-molybdenum @10t-240-150-220-2-1 kg/ha, respectively. The entire quantity of cowdung, TSP, boron,molybdenum were applied during final land preparation and one third of urea and MoP were applied during pit preparation. The remaining urea and MoP were applied in 3 equal installments at 15, 30 and 45 days after transplanting. Other than insect, disease control and all other agronomical operations were done as and when needed. Five plants were randomly selected from each replication for data collection. Data were recorded on days to curd initiation, days to 1st harvest, plant height (cm), curd length (cm), curd diameter (cm), marketable curd weight (g), only curd weight (g), marketable yield (t/ha) and statistically analyzed
