Abstract/ Executive Summary:

The experiment was conducted with two advanced cauliflower lines with one check variety at the four locations of Bangladesh Agriculture Research Institute (BARI) which included Joydebpur, Jamalpur, Comilla and Ishurdi during June-September, 2013 to observe the performance of advanced cauliflower lines in summer season. In average of four locations, it was observed that the line CL-0172 was earlier (77days) than the line CL-0171 (80 days) but BARI Fulcopi 1 does not produce curd due to high temperature. The highest average marketable curd weight (387.32 g) was recorded from the line CL- 0172 followed by the line CL-0171 (334.82g).The highest average calculative per hectare yield (16.24t) was recorded from the line CL-0172 and the lowest yield (13.94t) was recorded from the line CL-0171. Considering the overall performance the advanced line CL-0172 was being proposed to release a summer variety.

Keywords: RYT, Advanced summer cauliflower lines, Marketable curd, Yield

Location: Joydebpur, Jamalpur, Comilla and Ishurdi

Start Date: 00-06-2013

End Date: 00-09-2013

Program Area: Variety and Species

Commodity: Cauliflower

Objectives:

To observe the performance of advanced cauliflower lines in summer season

Methodology:

The experiment was conducted at four locations of Bangladesh Agriculture Research Institute (BARI), which included Joydebpur, Jamalpur, Comilla and Ishurdi during June to September, 2013. The experiment was laid out in RCB design with three replications. Seeds of two advanced lines (CL- 0171, CL- 0172) and BARI Fulcopi-1 (check) were sown on 15 June -18 July, 2013 in seedbed. Thirty-day-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 50% curd initiation, days to 1st harvest, harvest duration (days), plant height (cm), leaf number (no.), curd length (cm), curd diameter (cm), whole plant weight (kg), marketable curd weight (kg), only curd weight (g), marketable yield (t/ha) and statistically analyzed.
