The present investigation was carried out for Seed invigouration treatments and durations on seedling parameters of onion (Allium cepa L.cv- Indrayani). Analysis of variance for the laboratory data revealed that significance mean sum of squares due to seed priming treatments were observed for all the characters under study. The mean performance of seed germination % ranged from 72.75 to 85 with a grand mean of 81.13%.All the treatments were significantly higher in comparison to control. Among the significant treatments for Root length, Shoot length, Seedling length (cm), Seedling fresh weight (mg) and Seedling dry weight (mg), T5 (GA3@100ppm) (24 hrs) was found significantly higher in comparison to other treatments. The mean performance of seedling vigour index I ranged from 897.00 to 1449.25 with a grand mean of 1190.96.The mean performance of seedling vigour index II ranged from 200.79 to 327.25 with a grand mean of 277.81. For seedling vigour index I and II, Treatment, T5 (GA3@100ppm) (24 hrs) was significantly higher in comparison to other treatments. It is concluded from the present investigation of seed treatments with different kind of priming exhibited significant effect on seed germination and seedling characteristics. Seed priming with GA3@100ppm for a duration of 24 hrs affected all the characters significantly in laboratory experiment. Thus, seed priming with GA3@100ppm for a duration of 24 hrs followed by T10Garlic extract solution @1:5 for the duration of 6 hrs is useful for improving germination and seedling characteristics of onion (Allium cepa L cv.– Indrayani).
