Abstract
The storage potential of JRO 204 and JRO 524 jute seeds was undertaken with
seven seed treatments viz. captan @ 2g per kg seeds, chlorox @ 2g per kg seeds, boric
acid @ 2 g per kg seeds, calcium chloride @ 2 g per kg seeds, tannic acid @ 2 g per
kg seeds, ascorbic acid @ 2 g per kg seeds, control and were packed in cloth bag and
polythene bag (700 gauge) and stored under ambient conditions for 12 months. The
JRO 524 jute variety recorded higher germination and seedling vigour parameters
compared to the JRO 204 at the end of 12 months of storage. Among the seed
treatments, seed treated with tannic acid recorded higher germination (84.81%) and
other seed quality parameters at the end of storage period. Seeds packed in polythene
bag recorded higher germination (76.28%), vigour parameters with lower electrical
conductivity and moisture content as compared to seeds stored in cloth bag at the end
of storage period. In the interaction effect of varieties and treatments (VxT), JRO 204
and JRO 524 seeds treated with tannic acid recorded significantly satisfactory higher
germination (83.38% and 86.23% respectively) as per minimum seed certification
standards and other vigour parameters throughout the storage period. In the
interactions between varieties and packaging materials (VxC), JRO 524 variety seeds
packed in polythene bag was superior in all the seed quality parameters compared to
cloth bag. In the interactions of seed treatments and containers (TxC), seed treated
with tannic acid and stored in polythene bag recorded higher satisfactory germination
(85.61%) with higher vigour parameters at the end of storage period. Among the
interactions of varieties, seed treatments and containers (VxTxC), JRO 524 seeds
treated with tannic acid and packed in polythene bag recorded higher satisfactory
germination (87.36%) and other seed quality parameters at the end of storage period.
