Description The field and laboratory experiments were conducted to study the hydropriming with
chemicals on field performance and seed quality and pre storage seed treatment on viability
of high and low vigour seeds of sesame cv.DS-1. During Kharif 2009 at the Department of
Seed Science and Technology, Agricultural College, Dharwad. The field experiment
consisted of two factors viz., the main factor high and low vigour seeds., the sub factor
consisted of seven treatments viz., Hydro priming, Hydro priming with KCI(2%),
hydropriming with KH2PO4 (2 %), hydropriming with GA3 (500 ppm), hydropriming with
CaCl2 (0.5%), priming with cow urine (50 %) and untreated control. The results showed
significant difference due to seed vigour level, hydropriming with chemicals and their
interaction effect. Among treatments hydropriming with GA3 (500ppm) was significantly
superior with respect to growth, yield and seed quality parameters followed by hydropriming
with CaCl2 (0.5%) as compared to control irrespective of the seed vigour. Hydropriming with
GA3 (500ppm) recorded the highest values with respect to plant stand (90.67 plants/plots),
plant height at 30 days (50.17 cm), 60 days (91.33 cm) and at harvest (115.00 cm), days to 50
per cent flowering (43.67 days), thousand seed weight (3.21 g), number of capsules (60.53
per plant), seed yield per plant (8.58g) seed yield per plot (577.67g) and seed yield per
hectare (5.32 q ha-1) as compared to untreated control irrespective of the seed vigour.Pre
storage seed treatment study results indicated that seed treatment with thiram (3 g kg-1 seed),
significantly superior with respect to seed quality parameters at the end of the six months of
the storage period followed by Chlorax (3 g kg-1seed), as compared to un treated control in
both high and low vigour seeds of Sesame cv.DS-1.
