Abstract/ Executive Summary:

The experiment was conducted at Manikganj, Kishoreganj and Comilla during 2008-09 to assess the optimum sowing date of advanced breeding line BJC-2197 of deshi jute for seed production at late season. It was laid out in RCBD design with three replications. The cultivar CVL-1 was used as control. Different sowing dates viz., 15 July, 30 July, 15 August, 30 August and 15 September were arranged as treatment of the study. The crop was harvested at proper maturity of the fruits of seed crop. Results revealed that the highest seed yield produced at Manikganj (1002.36 kg/ha) which was followed by Kishoreganj (959.01 kg/ha) and Comilla (949.01 kg/ha) sown on 15 July. The variety CVL-1 yielded numerically higher than advanced breeding line BJC-2197. Results also showed that comparatively higher yield produced at Manikganj which was followed by Kishoreganj and Comilla. The lowest seed yield and yield contributing characters were recorded from 15 September sowing at all the stations. All other variables were also gave the highest results according to seed yield.

Keywords: Jute, date of sowing, deshi jute

Location: Jute Agriculture Experimental Station Manikganj and Jute Research Regional Station Kishoreganj and Chandina, Comilla.

Start Date: 01-07-2008

End Date: 31-01-2009

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

1.To find out the optimum of date of sowing on seed production of advanced breeding line BJC-2197 of deshi jute in late season in order to improve the yield and quality of seed.

Methodology:

The experiment was conducted at Manikganj, Kishoreganj and Comilla during 2008-09. Advanced breeding line BJC-2197 of deshi jute was used as study material for seed production at late jute season. The experiment was laid out in RCBD design with three replications. Five different sowing dates viz., 15 July, 30 July, 15 August, 30 August and 15 September, and study materials BJC-2197 with control variety CVL-1 were tested as treatments. Unit plot size would be 4.0m x 2.5m. Space between plot to plot and around the field 1.0m and between replications 1.5m. were maintained. Seeds were sown in line of 30 cm apart. Other cultural and intercultural practices were attended as per BJRI's recommendation. The mean difference among the treatments were adjudged by the New Duncan`s Multiple Range Test.

Achievement/Findings:

The highest seed yield produced at Manikganj (1002.36 kg/ha) which was followed by Kishoreganj (959.01 kg/ha) and Comilla (949.01 kg/ha) sown on 15 July. The variety CVL-1 yielded numerically higher than advanced breeding line BJC-2197. Comparatively higher yield produced at Manikganj which was followed by Kishoreganj and Comilla. The lowest seed yield and yield contributing characters were recorded from 15 September sowing at all the stations. All other variables were also gave the highest results according to seed yield.
