Abstract/ Executive Summary:

The experiment was conducted at Rangpur and Jessore during 2006-07 to assess the optimum sowing date of BJRI Tossa Pat-4 (O-72) for seed production at late season. The experiment was laid out in RCBD design with four replications. Different sowing dates viz., 15 July, 30 July, 15 August, 30 August and 15 September were used as treatment. Results showed that at the experiment of Jessore station, the highest seed yield was obtained crop sown on 30 July (1536.50 kg/ha) which was followed by 15 July (1289.10 kg/ha), 15 August (1115.62 kg/ha) and 30 August (974.24 kg/ha). At the experiment of Rangpur station, the highest seed yield was obtained sown on 15 July (1210.50 kg/ha) which was followed by next date of sowing up to 15 September. The lowest seed yield and yield attributes were recorded sown on 15 September at all the locations. Comparatively better yield were produced at Jessore station than Rangpur.

Keywords: Jute, Sowing date, Jute seed

Location: Jute Research Regional Station Rangpur and Sub Station, Monirampur, Jessore.

Start Date: 01-07-2006

End Date: 31-01-2007

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

1. To optimize the date of sowing of newly released tossa jute variety BJRI Tossa Pat-4 (O-72) for higher and quality fibre production.

2. To optimize the agronomic means viz., sowing and harvesting time, post harvest processing etc. of juteseed crop.

3. To improve the yield and quality of jute, seed. 4. To generate information about jute seed by adopting different seed technological research.

Methodology:

The experiment was conducted at Jute Research Regional Station Rangpur and Sub Station, Monirampur, Jessore during 2006-07 to assess the optimum sowing date of newly released tossa jute variety BJRI Tossa Pat-4 (O-72) for seed production at late jute season. The experiment was laid out in RCBD design with four replications. Five different sowing dates viz., 15 July, 30 July, 15 August, 30 August and 15 September was used as treatment. 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. The crop was harvested at proper maturity of the fruits of seed crop. Other cultural and intercultural practices were attended as per BJRI's recommendation.
