Effect Of Sowing Date On Fibre Yield And Yield Attributes Of Advanced Breeding Line O-0412-9-4 And O- 043-7-9 Of Tossa Jute (Corchorus Olitorius L.)

The experiment was conducted at Jute Agriculture Experimental Station (JAES), Manikganj and Jute Research Sub Station (JRSS), Jashore during 2019- 2020 to determine the optimum sowing date of advanced breeding line O-0412-9-4, O-043-7-9 of tossa jute and BJRI Tossa Pat 5 (O-795) used as control. The experiment was laid-out in factorial RCBD with three replications. Crops were sown on four different dates viz., 30 March, 15 April, 30 April and 15 May as treatment variables. Plants were harvested at 120 days after sowing. All crops were given normal cultural practices. Results showed that advanced breeding line O-0412-9-4 and O-043-7-9 sown on 30 March to 10 April gave significantly higher fibre yield of 3.11 and 3.04 t ha-1, respectively) at Manikganj and 3.13 and 3.11 t ha-1, respectively at and Jashore.
