Description A laboratory experiment was conducted at National Seed Project,
UAS, Bengaluru during September 2012 to April 2013 for a period of seven
months. The study comprised of two hybrids viz., KRH-2 and KRH-4, three
containers viz., poly pouches, super grain bag and airtight container and
two desiccant viz., silica gel and zeolite beads with FCRD in three
replication.
The results revealed that among both the hybrids KRH-4 seeds
recorded less moisture (9.48%), maximum germination (77.41%), vigour
indices I and II (1211 and 384),TSS (12.78 mg/g), minimum seed insect
damage (11.11%) and seed infection (20.72%) and higher TSP (1.45 mg/g),
alpha amylase (0.66 cm) were recorded in KRH-2 at the end of seven months
of storage. Among containers super grain bag noticed less moisture (9.32%),
highest germination (78.44%), vigour indices I and II (1280 and 396),TSS
(13.05 mg/g), less seed insect damage (10.26%) and seed infection (18.50%)
and higher TSP (1.55 mg/g), alpha amylase (0.67 cm) were noticed in KRH-2
at the end of seven months of storage. Among desiccants zeolite beads (30%
of seed weight) observed less moisture (8.39%) highest germination
(78.17%), vigour indices I and II (1312 and 395), TSS (13.08 mg/g), less
seed insect damage (9.70%) and seed infection 17.44%) and higher TSP
(1.56mg/g) alpha amylase (0.67cm) were observed in KRH-2 at the end of
seven months of storage.
Thus it can be concluded that the KRH-4 seeds packed with zeolite
beads (30% of seed weight) in super grain bag can be safely stored for one
planting season.
