Abstract/ Executive Summary:

An experiment was conducted at the Regional Cotton Research Farm, Jagadishpur, Jessore during 2009-10 to evaluate six cotton varieties. Among them, four were hybrid cotton varieties and another two were inbreeds taken as control. Significant differences were found among the varieties for all traits except number of plants/ha and plant height at harvest. Hybrid variety SSC-3 performed well in terms of seed cotton yield (3570.33 kg/ha), lint yield (1404 kg/ha) and ginning out turn (GOT) percentage (43.83%). The highest 2.5% span length (31.44 mm) was found in hybrid HSC-4 and the lowest micronaire value of 3.87 mμ was found in hybrid SSC-2.

Objectives:

To assess the performance of introduced cotton hybrid varieties over local varieties and
To select the best performed hybrids among the introduced cotton hybrid varieties.

Methodology:

The experiment was conducted at the Regional Cotton Research Farm, Jagadishpur, Jessore during the season 2009-10. Six genotypes were included in the experiment of which SSC-1, SSC-2, SSC-3 and HSC-4 were introduced from China. The genotypes CB-9 (developed from S1/91/646) and CB-10 (developed from BC- 0397) were taken as control varieties which were collected from Sreepur, Gazipur and Sadarpur, Dinajpur, respectively. The trial was laid out in a Randomized Complete Block Design with three replications. The seeds were sown on 13 August 2009. Unit plot size was 5m×3.6m and plant spacing was 0.90m×0.45m. Data were collected from middle two rows (5m×1.8m) of each plot to minimize border effects. Green manure (Sunhemp) was plough down at the age of 45 days. Cow-dung (3t/ha) was applied at the time of final land preparation. The nutrient elements such as Nitrogen (N), Phosphorous (P), Potassium (K₂O), Sulpher (S), Boron (B), Magnesium Sulphate (MgSO₄) and Zinc Sulphate (ZnSO₄) were applied in the row at the rate of 23-48-50- 14-8-8 and 8 kg/ha, respectively as basal dose. Then 69 kg N was applied in three equal splits at 25, 42 and 55 days after sowing as top dressing. Another doses of Phosphorus, Potassium, Gypsum, Borax, Zinc Sulphate and Magnesium Sulphate were applied in third top dressing at the rate of 36-39-5-2-2 and 2 kg/ha, respectively. Normal cultural and plant protection measures were followed. Ten plants were chosen at random from each plot to record the number of vegetative branches/plant, primary fruiting branches/plant, secondary fruiting branches/plant, node number of 1^st fruiting branches (NFB)/plant, number of burst bolls/plant, number of un-burst bolls/plant, plant height at harvest and average weight of seed cotton/boll. Days to 1^st flower and days to 1^st boll split were recorded when 50% plants bore flowers and opened bolls. Seed cotton picking percentage and seed cotton yield data were also collected from the harvested areas. Different lint quality was measured after ginning. Ginning out turn (GOT) is the proportion of fiber in seed cotton and was measured and expressed.

Achievement/Findings:

SSC-3 should better performance according to its high yield potential than the other genotypes. Earliness were present in the hybrid cottons due to seed cotton picking percentage, but control variety CB-9 produced the highest weight of seed cotton/boll, longest (50%) span length and best uniformity ratio.
