Abstract/ Executive Summary:

The experiment was conducted in eight (8) locations of ten Zonal offices of Cotton Development Board during the year 2011-12. Here two accessions SR-08 and JA/2000/526 were included in this trial for adaptability test. At different locations the line JA/2000/526 showed the yield range of 1315 to 3880 kg/ha and mean yield was 2523 kg/ha.

Keywords: Upland Cotton, On-farm level, Yield

Location: Jessore, Kusthia, Jhinaidah, Chuadunga, Thakurgoan, Mymensingh, Rajshahi and Dhaka

Start Date: 00-00-2011

End Date: 00-00-2012

Program Area: Crop-Soil-Water Management

Commodity: Cotton

Objectives:

To investigate the yield gap between on-station and on-farm level.

Methodology:

The experiment was established at ten zonal offices, such as, Jessore, Kusthia, Jhinaidah, Chuadunga, Thakurgoan, Mymensingh, Rajshahi and Dhaka. Augmented design with no replication was followed. The sowing period covered the time 23-7-11 to 25-8-11. The plot size was 20m X 22.27.m, plant spacing was 90cm X 45cm for Dhaka and Rangpur region but in Jessore region 90cm X 60cm was followed. Two or three water soaked seed were sown per hole. The nutrient elements such as Nitrogen (N), Phosphorus (P), Potassium (K), Sulpher (S), Boron (B), and Magnesium (MgS04) were applied in the row at the rate of 6.45-16-11-5-0.92 and 5.4 kg/ha respectively as basal dose. At the 1st side dressing of the nutrient elements such as Nitrogen (N), Potassium (K) and Zn were applied at the rate of 9.6-15 and 1.94 kg/ha at the seedling age of 25 DAE one side of the cotton row. After 42 days of DAE the second side dressing was applied at the rate of 24. 19-12.00-27.5-5.76-l.22 kg/ha Nitrogen (N), Phosphorus (P), Potassium (K), Sulpher (S) and Boron (B) respectively just opposite side of the 1st side dressing. When the plants appeared at 62 days, third side-dressing was done at the rate of 24. 19-12.00-33.00-5.03- 0.925 kg/ha of Nitrogen (N), Phosphorus (P), Potassium (K), Sulpher (S) and, Boron (B) respectively opposite side of the 2nd side dressing. The last or fourth side-dressing was done at the plant age of 75 days at the rate of Nitrogen 16.13 kg and potassium (K) 22 kg Iha respectively. Two times thinning was done after 11 days and 21 days of seed emergence keeping one seedling per stand. Data were collected on days to first flowering, days to first boll split, plant height, weight of seed cotton yield per plot, Plant population at harvest, Ginning data and lint characteristics also evaluated. The collected data were analysed through MSTAT program. Data were collected on days to first flowering, days to first boll split, plant height, weight of seed cotton yield per plot, Plant population at harvest, Ginning data and lint characteristics also evaluated.

Achievement/Findings:

At different locations, the line JA/2000/526 showed the yield range of 1315 to 3880 kg/ha and mean yield was 2523 kg/ha. Due to wide adaptability and high yield potentiality, the accession JA/2000/526 should be released as a variety.
