Abstract/ Executive Summary:

Two tossa jute varieties 0-9897 and OM-1 were sown at ten days interval on 15 July, 25 July, 5 August, 15 August, 25 August, 5 September, 15 September, 25 September and 5 October, 2001 to determine sowing times effects on the phenology, growth and seed yield. Days required in attaining different phenological events like days to 50% flowering, days to 50% pod formation, days to maturity and days from anthesis to maturity decreased gradually with the delayed sowing times. Seed yield of 0-9897 was higher than OM-1 and it increased gradually from 15 July and reached to a plateau at 5 September sowing. The highest seed yield (1406 Kg ha^-1) of 0-9897 obtained at 5 September sowing which was however identical to the yield of 15 and 25 August sowings. The highest seed yield of OM-1 at 5 September sowing was 1326 Kg ha^-1. Seed yield of both the varieties decreased rapidly after 5 September sowing and it was lowest at 5 October sowing.

Start Date: 01-07-2001

End Date: 30-03-2002

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

To determine the effect of sowing times on the phenology, growth and seed yield of tossa jute in late sown condition.

Methodology:

The experiment was conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Salna, Gazipur during July 2001 to March 2002. The location of the experimental site was 24°N latitude and 19°16' longitude with elevation of 8.4 meters above sea level. The soil of the experimental field belonged to shallow reddish-brown terrace type under Salna series of Madhupur tract. The soil was silty clay in nature, containing 33% clay, 30% silt and 26% sand with pH 6.5. The climate was sub-tropical in nature having frequent rainfall during August, September and October with gradual fall of temperature from the month of October. Two varieties of tossa jute namely 0-9897 and OM-l were sown at ten days interval on 15 July, 25 July,S August, 15 August, 25 August,S September, 15 September, 25 September and 5 October, 2001. The design of the experiment was split plot with three replications. Unit plot size was 4m x 3m and distance between plot to plot was 1m. Sowing times were assigned in main plots and varieties in sub plots. Jute seeds were sown at the rate of 2.5 kg ha^-1, in 30 cm apart rows. Light irrigation was given just after sowing to establish the seedlings properly. The excess seedlings were thinned out at 20 days after sowing. Two weeding were also done at 20 and 35 days after sowing just before the top dressing of urea. Phenological changes of jute seed crop occurred due to sowing times was observed frequently. Days to first flowering, days to 50% flowering, days to first pod formation, days to 50% pod formation and days to maturity of seed crop were recorded. The crops were harvested from 5 December to 22 January depending up on the maturity of crops sown at different dates. When 70% pods attained brown colour, it was considered as ready for harvesting. For determination of yield contributing characters of jute seed crop, ten plants were randomly selected from each plot and plant height, number of branch plane^-1, pod plane-1 seed pod^-1,, pod length, pod diameter, 1000 seed weight were recorded. The harvested crop of each sowing date was dried in the sun for 5 days. Jute seed was then threshed out by beating the pods with stick. It was cleaned and dried in the sun on the cemented floor till its moisture content came down to 10-12%. Yield of jute seed crop was determined by harvesting an area of 1 m² and converted into kg ha^-1, at 10% moisture content.

Achievement/Findings:

The present study was to determine the sowing times effects on the phenology, growth and seed yield. Days required in attaining different phenological events like days to 50% flowering, days to 50% pod formation, days to maturity and days from anthesis to maturity decreased gradually with the delayed sowing times. Seed yield of 0-9897 was higher than OM-1 and it increased gradually from 15 July and reached to a plateau at 5 September sowing. The highest seed yield (1406 Kg ha^-1) of 0-9897 obtained at 5 September sowing which was however identical to the yield of 15 and 25 August sowings. The highest seed yield of OM-1 at 5 September sowing was 1326 Kg ha^-1. Seed yield of both the varieties decreased rapidly after 5 September sowing and it was lowest at 5 October sowing.
