Influence of seed enhancement techniques on seed quality in onion (Allium cepa L.)

Abstract

The experiment was carried out at Seed Quality and Research Laboratory, Seed Unit, University of Agricultural Sciences, Dharwad to study the effect of seed enhancement techniques on seed quality in onion. Seed quality parameters were significantly influenced between the seed lots and seed enhancement techniques. Fresh seed lot (L1) recorded significantly higher germination (89.56 %), root length (8.63 cm), shoot length (11.14 cm), seedling vigour index (1773), as compared to old seed lot (L2) 86.44%, 8.28 cm, 10.67 cm, 1640 respectively. While encrusting with Thiram: Genius coat (1:1.2) (T4) recorded significantly higher germination (91.50%), root length (9.11 cm), shoot length (11.62 cm), seedling vigour index (1897) and lowest was recorded in control (T6) 84.83%, 8.05 cm, 10.33 cm, 1559 respectively therefore encrusting with Thiram: Genius coat (T4) (1:1.2) can be used in order to enhance the seed quality of onion var.
