Description The effect of organics and liquid fertilizers on seed yield, quality and
influence of seed treatments on storability of sunflower seeds were studied during the
year 2011-12. A field experiment was conducted during kharif season at Water and
Land Management Institute (WALMI) Farm while storage experiment at Seed
Research Laboratory, National Seed Project (NSP), University of Agricultural
Sciences, Dharwad.
Field experiment comprised of three organics (FYM, Vermicompost and
NPK) and five liquid foliar sprays (Panchagavya, Vermiwash, Biodigester liquid,
Cow urine and Borax) replicated thrice laid out in split plot design. The results
revealed that application of RDF (35:50:35 kg N:P2O5:K2O per ha) +FYM (8 t/ha) +
borax (0.5%) recorded higher plant height (87.53 cm), SPAD values (37.29) and it
also recorded significantly higher number of seeds per capitulum (882), seed yield
(986 kg/ha), oil content (42%), seed germination (92.67%) and seedling vigour index
(3326) compared to FYM (50%) + Vermicompost (50%) equivalent to RDP+
Biodigester liquid (10%).
The storage experiment comprised of three containers (Cloth, Polythene bag
and Vacuum packing) and six seed treatments (Sweet flag rhizome, Neem leaf,
Custard apple seed powders, Deltamethrin and Vitavax) stored for 11 months under
ambient condition. The seeds were treated with vitavax (3 g/kg) recorded significantly
higher hundred seed weight (4.36 g), seed germination (84.37%), root and shoot
length (17.66 and 16.25 cm), vigour index (2865), lower electrical conductivity (232
dS m-1) and seed moisture content (9.14%) at the end of 11 months of storage
compared to other treatments. Among the containers the seeds stored in vacuum
packing recorded significantly higher hundred seed weight (4.36 g), germination
(84.45%), root and shoot (18.05 and 16.70 cm) length, vigour index (2935), lower
electrical conductivity (225 dS m-1) and seed moisture content (8.57%) compared to
cloth bag at the end 11 months of storage period.
