Description An investigation was carried out with two experiments at Department of Seed Science
and Technology and MARS, University of Agricultural Sciences, Dharwad during 2009-
2010. The storage experiment was laid out in CRD to study the effect of fungicidal seed
treatment on seed quality during storage. The experiment consisted nine seed treatments with
fungicides viz., T1 (Carboxin + Thiram @ 3 g kg-1 seeds i.e. Vitavax Power), T2 (Sulphur @ 3
g kg-1), T3 (Thiram @ 3 g kg-1), T5 (Carbendazim + Iprodione @ 3 g kg-1 i.e. Quintal), T6
(Carbendazim @ 3g kg-1 i.e. Bavistin), T7 (Captan + Hexaconazole @ 3 ml kg -1 i.e. Takat),
T8 (Sulphur + Thiram @ 1.5 g + 1.5 g kg-1) and T9 (Control). The seeds treated with carboxin
+ thiram (vitavax power) @ 3 g kg-1 seeds recorded significantly higher germination (73.75
%), root length (16.75 cm), shoot length (16.73 cm), vigour index (2469), seedling dry weight
(163.0 mg-5 seedlings), lower electrical conductivity (0.866 dSm-1) and moisture content
(12.18%) at the end of nine months of storage over the control.
The field experiment was laid out in RCBD to study the effect of fungicidal seed
treatment on seed yield, quality and control of smut incidence in rabi sorghum. The
experiment consisted 11 seed treatments. The seeds treated with carboxin + thiram (vitavax
power) just before sowing @ 3 g/kg seeds were recorded significantly maximum ear head
length, breadth, weight (18.9 cm, 13.4 cm, 42.2 g respectively), number of primaries per ear
head (33.7), seed weight per plant (36.1 g), seed yield per plot (1.079 kg), seed yield per
hectare (1521.9 kg) and lesser smut incidence (1.10%). The higher gross, net returns and B:C
ratio (34,037, 26,217 Rs/ha, 4.35 respectively) and seed quality parameters were significantly
higher in the same treatment over the control.
