Abstract/ Executive Summary:

Accurate date of sowing can play an important role for cost effective seed production. In C. capsularis and C. olitorius jute, the seed yield showed significant differences in respect of date of sowing but varietal difference was insignificant. Seed yield increases with the increases of date of sowing in both cases. The inter action effect was insignificant in C. capsularis but significant in C. olitorius. Numerically CVL-1 showed the highest seed yield (903 kg/ha) followed by CVE-3 (900 kg/ha) in C. capsularis and O-72 (649 kg/ha) followed by O-9897 (629 kg/ha) in C. olitorius jute.

Keywords: Direct seeding method, Stem cutting method, Quality seed

Location: Jute Agriculture Experimental Station, Manikganj

Start Date: 01-03-2009

End Date: 31-12-2009

Program Area: Seed Technology

Commodity: Jute

Objectives:

1.To find out the accurate date of sowing for getting quality jute seed and

2. To compare between direct seeding and stem cutting method for quality seed production.

Methodology:

Sowing date is an important factor for quality jute seed production. Deshi jute seeds are produced directly from mother plants and tossa jute seeds are produced through stem and top cuttings. Four deshi jute varieties namely CVL-1, CVE-3, BJC-7370 and BJC-83; and four tossa jute varieties namely O-9897, OM-1, O-72 and JRO-524 were used to conduct the experiment in RCBD with three replications. In all cases unit plot size was 3 m x 2 m and line to line distance was 30 cm. First sowing was done on 06/4/09 for deshi jute and 23/4/09 for tossa jute. The sowing was completed following one month interval up to 04/8/09. After harvest data were taken on seed yield only.

Achievement/Findings:

Quality seed yield of jute varies with the time of sowing. It increases with the increases of date of sowing from April to August in both deshi and tossa jute varieties. Comparatively deshi jute varieties give higher seed yield than tossa jute varieties.
