Effect of Seed Source and Seedling Age on different Growth Characters of White Jute Seedlings under Green House and Field Conditions

A series of experiments were conducted to evaluate the plant establishment of white jute seeds collected from five different sources of Bangladesh. The experiments were conducted at greenhouse of BJRI, Dhaka and field of Jute Agriculture Experimental Station (JAES), Manikganj during March to June 2008. 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 Manikganj and farmers of Kishoreganj locations. Two different conditions were (i) Greenhouse and (ii) Field. The four ages of seedlings were 30, 40, 50, and 60 days. The cv. CVL-1 of the Corchorus capsularis L. was used as study material. Randomized completely block design with three replication were followed. Results revealed that the Seedling height, Seedling base diameter and Seedling root length for plant establishment of CVL-1 seed's varied significantly due to seed sources in both the condition of green house and field. BJRI and BADC seed sources showed better performance than the others. The above mentioned attributes also showed significant variations for seedling ages in both the conditions. The highest values were observed in 60 days of seedling age and the lowest in 30 days. The interaction of seed sources and seedling ages were highly significant and the seedlings from BJRI seeds showed the highest Seedling height, Seedling base diameter and Seedling root length at 60 days of seedling age.
