Abstract:

The present study was conducted with four cauliflower genotypes viz., CL-170, CL-171, CL-172 and BARI Fulcopi-1 and three sowing dates viz., 25 August, 5 September and 25 October. The experiment was conducted during the winter season of 2013-14 at the field laboratory of Horticulture Department of Sylhet Agricultural University (SAU) to evaluate growth and yield of cauliflower genotypes and to identify the suitable planting time in Sylhet conditions. Results showed that sowing dates and genotypes had significant influenced on growth and yield of cauliflower. The lowest days to first curd harvest was from the plant grown in 5 October sowing (86.25 days) while it was the highest from the plants in 25 August sowing (91.58 days). The highest whole plant weight was recorded from the plants of 25 August sowing (0.78 kg) while the highest individual curd weight (0.48 kg) and only curd weight (0.31 kg) was recorded in 15 September sowing. The plants in 15 September sowing produced the highest curd yield (16.32 t ha-1) followed by 15 August sowing (15.64 t ha-1). Days to first curd initiation and days to first harvest were significantly different among the genotypes. CL-171 was the earliest to first harvest (88.69 days) while the genotype CL-170 required 91.22 days to first harvest. The genotype BARI Fulcopi-1 had the highest whole plant weight (0.97 kg), marketable curd weight (0.55 kg) and only curd weight (0.32 kg). Among the four genotypes, BARI Fulcopi-1 produced the highest marketable curd yield (18.7 t ha-1) followed by CL-171 (16.37 t ha-1). Whole plant weight, marketable curd weight and only curd weight were significantly influenced by the interaction of genotypes and sowing dates. The highest marketable curd was harvested from the genotype BARI Fulcopi-1 (20.74 t ha-1) when grown in 15 September sowing which was followed by the same genotype from 25 August sowing (18.7 t ha-1).
