Abstract
The
experiment was conducted at two locations; Manikganj and Jessore to
determine seed yield performance of two tossa jute varieties (BJRI
Tossa Pat-7 and BJRI Tossa Pat -5) sown at five sowing dates viz., 30
July, 15 August, 30 August, 15 September and 30 September during
2016-17. The experiment was laid out in RCB design with three
replications. The cultivar BJRI Tossa Pat-5 was used as control.
Results revealed that BJRI Tossa Pat-7 yielded higher at Manikganj
(766.67 kg ha-1) which was 13% higher than that as was obtained at
Jessore (678.33 kg ha-1. The respective seed yield as was shown by
BJRI Tossa Pat -5 at these two sites were 653.87 and 584.67 kg ha-1.
The higher seed yield of the BJRI Tossa pat -7 was attributed to
higher values of seed weight per plant (5.46-5.85 g) as compared to
the BJRI Tossa pat-5 (3.62-3.80 g). BJRI Tossa Pat-7 sown on 15th
and 30th August at Manik Gonj showed significantly higer seed yields
(989-995 kg) compared to those (1045 and 973.33 kg) of BJRI Tossa
Pat-7 and BJRI Tossa Pat-5 sown at Jessore. BJRI Tossa Pat-7 sown on
15th and 30th August at Manik Gonj had also significantly higher
values in yield attributes such as number of pods/plant (34.9-37.77),
seeds/pod (179-185) and seed weight per plant (7.03-9.23 g). The
lowest seed yield (298.33 kg) was obtained BJRI Tossa Pat-7 sown at
Jessore on 15th September which was attributed to the lowest values
number of pods per plant (21.17-26.43), seeds/pod (148-161) and
seed weight per plant (4.43 – 6.44 g). 1000 seed weight and
germination % significantly varied at Manikgonj while these two seed
attributes along with seed moisture after harvest was not
significantly varied due to the treatments. At Manik Gonj the
heaviest seeds (1.94 g/1000) was obtained with v2s3 and significantly
higher germination (89-92.67%) were obtained with v2s2 and v2s3
treatments.
