Abstract:
The experiment was carried out at Seed Testing Laboratory, Beej Bhaban,
BADC, Gabtoly, Dhaka to select the suitable varieties and the suitable devices
for the storage of T. Aman seeds at farmer’s level. Five T. Aman varieties viz:

= Polythene in gunny bag, D
= Gunny bag were used as treatment in
this experiment. The experiment was carried out following completely
randomized design with four replications. Data were collected in each month
from January to July on moisture (%), germination (%), germination (%) after
accelerated aging test, speed of germination, electric conductivity, seedling
length, biomass production and imbibitions (%). The result revealed that BINA
dhan7 showed the highest germination (83-86%) and highest seedling length
(20-22.62 cm) and BRRI dhan52 showed the highest speed of germination
(11.12-25.30) as well as the highest biomass production (0.175-0.207 gm/10
seedlings). Seeds stored in plastic drum performed better in maintaining
significantly higher germination (82-93%), the highest speed of germination
(26-55), the lowest electric conductivity (232-282 µm) for the storage period.
On the other hand, seeds stored in gunny bag showed the lowest germination
(75-82%, the lowest speed of germination (12.52-25.61), the highest electric
conductivity (240-295 µm) at different months after preservation. Interaction of
plastic drum × BRRI dhan7 gave the highest germination (83-95%) and
interaction of plastic drum × BRRI dhan52 gave the highest speed of
germination (30.58-56.00). From the present study, it may be concluded that
BINA dhan7 and BRRI dhan52 as the variety, plastic drum as a storage device,
and the interaction of D

(plastic drum× BINA dhan7) as well as D
(Plastic drum × BRRI dhan52) performed better in maintaining the T. Aman
seed quality during storage for six months (January-June) at the farm condition.
