Performance of CVL-1 Seedling Growth and Dry Weight Attributes Under Greenhouse and Field Conditions as Affected By Seed Source and Seedling Age

Experiments were conducted to evaluate the plant establishment of white jute (Corchorus capsularis L.) 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.
