Abstract:
An experiment was conducted at experimental field of Bangladesh Jute
Research Institute Regional Station. Rangpur during July 2004 to January 2005. Seed
quality components were tested in the Laboratory of' the Agronomy Division of WRI.
Dhaka. The objectives were to find out the appropriate sowing dale. sowing method
and interaction effect of sowing date and sowing method on the yield and quality of
jute seed in the late season. The experiment consisted of five sowing dates viz.. July
IS. July 30, Auuust 15, August 30 and September 15: two sowing methods viz., line
and broadcast with a variety 0-72. The experiment was laid out in randomized
complete block design with four replications. Results showed that sowing date
significantly affected seed yield and yield components. The higher seed yield
(1167.20 kg hi') obtained from the crops sown on August 15 compared to the crops
of other sowing dates. The seed produced from August IS sowing also gave better
pertorinanee regarding seed quality express as 1000 seed weight (2.16 g). germination
percentage (96.00%). vigour index (67.39) and moisture content (10.19%). There was
signilleant effect found in seed yield clue to sowing methods. l3ttt sowing methods
signilicaiitly afiected the seed quality components. The seed
110
,-, produced from line
sowing gave die highest 1000 seed weight (2.09 g), germination percentage (93.30%),
and lowest moisture content (10.43%) over broadcast sowing where vigour index
was
unaiTheted. The seed yield was significantly atiëeted by the interaction ol sowing date
and sowing method. The highest seed yield (11 S7.70 kg ha'') obtained from the crops
sown on August 15 in line sowing method. The vigour index of jute seed was
significantly affected due to interaction effect of sowing date and sowing method
where other quality components such as 1000 seed weight, germination percentage
and moisture content remained ttnaffeeted. The seed obtained fran, the crops sown on
August IS gave the higher valtie of vigour index (66.89 and 67.89 for line and
broadcast sowing respectively) in both the sowing methods. The crops sown on
August 15. in any ol' the sowing methods either line sowing or broadcast sowing
produced higher yield of quality seed.
