Abstract/ Executive Summary:

A series of experiments were conducted to assess the germination, vigour and emergence of jute seeds collected from five different sources of Bangladesh. The seed germination and vigour estimation experiments were laid out at the Agronomy laboratory, Bangladesh Jute Research Institute (BJRI), Dhaka in completely randomized design with five replication. The emergence experiments were conducted at greenhouse of BJRI, Dhaka and field of Jute Agriculture Experimental Station (JAES), Manikganj in randomized completely block design with three replication during March to June 2004. The treatments consisted of five different seed sources viz., i) Bangladesh Jute Research Institute (BJRI), ii) Bangladesh Agriculture Development Corporation (BADC) , iii), iv) Farmers of two different locations and v) Local market. Farmers source was divided into two sub-sources. The sub sources were farmers of Faridpur and farmers of Rangpur locations. Two different conditions viz., i) Greenhouse and ii) Field were used in conducting emergence experiment. The cv. O-9897 of the Corchorus olitorius L. was used as study material. The results revealed that the germination, vigour index and coefficient of germination of 0-9897 varied significantly due to seed sources. BJRI and BADC seeds had highest germination, vigour and emergence than all other sources. Emergence, relative emergence and survivability varied significantly for seed sources. Highly significant and positive correlations were observed among the germination, vigour index, coefficient of germination, emergence, relative emergence and survivability of 0-9897 seeds at both greenhouse and field conditions.

Keywords: Tossa jute, Germination, Vigour, Emergence, Relative emergence, Survivability.

Location: Crop management laboratory, Agronomy division of Bangladesh Jute Research Institute.

Start Date: 00-03-2004

End Date: 00-06-2004

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

To evaluate germination, vigour and emergence indicators of jute seed and their relationship as influenced by seed sources.

Methodology:

The laboratory experiments were conducted at the Crop management laboratory, Agronomy division of Bangladesh Jute Research Institute. The emergence experiment was conducted at greenhouse of Central Station, Dhaka and at field of Jute Agriculture Experimental Station, Jagir, Manikgonj of BJRI during March to June 2004. The treatments consisted of five seed sources viz., i. BJRI, ii. Bangladesh Agricultural Development Corporation (BADC), iii., iv) farmers of two locations and v. local market. The farmers seed source was divided into two sub-sources. The sub sources, were farmers of Faridpur and farmers of Rangpur locations. Primary seed samples of 250 g each from 20 farmers of each location were collected randomly. All the primary seed samples were mixed thoroughly to make a composite sample of each location. From the composite samples 500g seeds were taken and was regarded as submitted sample. The submitted seed samples were kept in brown paper bags. All the seed samples collected from the different seed sources were labeled properly and preserved in Gene Bank of BJRI at 20°C till the samples were used for studies. Working seed samples were taken from the preserved seed samples as per requirement. Total procedure was maintained following the rules of ISTA . Local market seed samples were collected and processed as that of farmers source. One hundred seeds were evenly distributed on the top of a filter paper placed with 5ml. tap water in plastic petri dish. The test was carried out in an incubator at 30±1⁰C temperature. The germination was recorded after 5 days and then calculated the germination percentage by following ISTA.

Achievement/Findings:

The results revealed that the germination, vigour index and coefficient of germination of 0-9897 varied significantly due to seed sources. BJRI and BADC seeds had highest germination, vigour and emergence than all other sources. Emergence, relative emergence and survivability varied significantly for seed sources. Highly significant and positive correlations were observed among the germination, vigour index, coefficient of germination, emergence, relative emergence and survivability of 0-9897 seeds at both greenhouse and field conditions.
