Abstract:

Small onion (Allium cepa var. aggregatum) is a popular Rabi bulb vegetable in the peninsular India. It is propagated by both seed and bulb. Hence experiment was conducted to study the effect of seed priming on small onion var. Co (On) – 5. The experiment was laid out in Completely Randomized Design (CRD) with two replications. Onion seeds were primed with following priming agents such as GA3, NAA, water at different concentration (50ppm, 100ppm) and different time periods (12, 18, 24 hrs). Data was recorded on germination percentage, shoot length, root length and vigour index. The experimental findings revealed that, seeds primed with GA3 100ppm for 12 hrs showed higher germination percentage (69.50 to 94 %), shoot length (7.02 to 9.44 cm), root length (5.01 to 6.91 cm) and Vigour index I (696.69 to 1630.44 ) over control, respectively. Seeds treated with GA3 100ppm for 12 hrs produced vigorous seedling with good root system which results in earlier transplanting of seedling by 9 days.
