Abstract/ Executive Summary:

Experiments were conducted to evaluate the plant establishment of white jute (Corchorus capsularisL.) seeds collected from five different sources of Bangladesh. The experiments were conducted at greenhouse of Bangladesh Jute Research Institute (BJRI), Dhaka and field of Jute Agriculture. Experimental Station (JAES), BJRI, Manikganj during March to June 2018. The treatments consisted of five seed sources viz., i) BJRI, ii) Bangladesh Agriculture Development Corporation (BADC), iii), iv) Farmers of two locations and v) Local market. Farmers source was divided into two sub-sources (farmer1 of Manikganj and farmer2 of Kishoreganj locations). Two different conditions were i) Greenhouse and ii) Field. The four seedling ages were 30, 40, 50, and 60 days. The cv. CVL-1 was used as study material. Randomized completely block design with three replication were followed. Results revealed that seedling growth and dry weight parameters varied significantly due to seed sources. The shoot height, base diameter, root length, shoot dry weight and root dry weights varied significantly due to seed sources in both the condition of greenhouse and field. BJRI and BADC sources showed better performance than the others. The attributes showed significant variations for seedling ages in both the conditions also. The highest values were observed in 60 days of seedling age. The interactions of seed sources and seedling ages were highly significant for all the growth and dry weight attributes. The BJRI seeds of 60 days of age performed the highest shoot height, base diameter, root length, shoot dry weight and root dry weights. Seeds from BJRI and BADC of the CVL-1 varieties showed better performances in terms of seedling growth and dry weight compared to seeds from farmers’ and local markets.

Keywords: White Jute (Corchorus capsularis L.), seedling ages, Shoot length, root length, Base diameter, Shoot dry weight, Root dry weight.

Location: Bangladesh Jute Research Institute (BJRI), Dhaka

Start Date: 01-03-2018

End Date: 30-06-2018

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

The present study was undertaken to evaluate the performances of seedling growth of white jute and their interactions as influenced by seed sources and seedling age.

Methodology:

The experiments were conducted at the Crop Management Laboratory, Agronomy division of Bangladesh Jute Research Institute (BJRI). The emergence experiment was conducted at Crop Management Laboratory, Agronomy Division of Bangladesh Jute Research Institute (BJRI), Dhaka as Greenhouse and at field of Jute Agriculture Experimental Station, Manikgonj of BJRI during March to June 2017. 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 farmer1 of Manikganj and farmer2 of Kishoreganj locations. The seed sample variety CVL-1 of Corchorus capsularis L. was used as study material. Primary seed samples of 250 g each from all sources and 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 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 200 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 of two locations. After collection of seed samples following tests were conducted. The soil of field opened with power tiller in the month of Mid February, then the land was prepared with the country spade. The Laboratory greenhouse soil was prepared and managed as per recommendation of BJRI. The land was made free from weeds and plant debris by hand collection. During final plot preparation NPK fertilizers were applied in the form of urea, triple super phosphate and muriate of potash. The rates of fertilizers used were 83-25-30-11 kg of NPKS ha^-1, respectively. Half quantity of N and the whole quantity of P, K and S were applied as basal dose. The other half quantity of N was top dressed in two equal splits at 15 DAS. Seeds used for the experiments had minimum of 80% germination. Seeds were sown on 25 March and 26 March in greenhouse and in the field, respectively. For each unit plot 500 seeds of each sample sources were sown in broadcast method and later covered with soil. In establishment test, 30, 40, 50 and 60-day-old seedlings were randomly collected from the greenhouse laboratory and as well as from field. The data of seedling shoot length, base diameter, root length, shoot dry weight and root dry weight of the seedlings were collected. Treatment mean differences were adjudged by DMRT following level of significance (0.05 and 0.01%)

Achievement/Findings:

CVL-1 seed’s seedling growth varied significantly due to seed sources and seedling age. The seedling height, base diameter, root length, shoot dry weight and root dry weights for seedling establishment of CVL-1 seed’s varied significantly due to seed sources in both the condition of green house and field. The interaction of seed sources and seedling ages were highly significant and the BJRI seeds of 60 days age showed the highest plant height, base diameter, root length, shoot dry weight and root dry weights. Seeds from BJRI and BADC of the CVL- 1 varieties showed better performances in terms of seedling growth and dry weight compared to seeds from farmers’ and local markets.
