Yield Trials Of Tossa Jute (Corchorus olitorius L.) At Dhaka And Manikganj Districts Of Bangladesh

The experiments were carried out at two locations of BJRI (Dhaka and Manikganj) during August, 2024 to January, 2025 to evaluate the yield and quality performances of some tossa jute varieties. BJRI Tossa pat 8, BJRI Tossa pat 9, O-9897, Robi-2, JRO-524 were used as experimental materials. The experiment was laid out in a randomized complete block design with three replications. Results showed that Dhaka significantly out-performed Manikganj in seed yield per plant (3.08 g vs. 2.70 g), largely due to a higher number of branches per plant. Varietal analysis revealed significant differences across all measured parameters. BJRI Tossa pat 9 consistently emerged as the highest-yielding variety (3.51 g/plant), demonstrating superior branching and capsule formation. Although Robi-2 had the highest plant population and height, its seed yield was the lowest (2.11 g/plant). Significant locations x variety interactions were observed for most traits, highlighting the importance of genotype-by-environment considerations. BJRI Tossa pat 9, particularly when grown in Dhaka, showed exceptional seed yield (3.78 g/plant), suggesting its strong adaptability and potential for increased jute seed production in specific regions. These findings underscore the necessity of location-specific varietal selection for optimizing jute seed yield and quality.
