MATERIALS AND METHODS
The present investigation was carried out during the year 2010-
2011 at K.R.C. College of Horticulture, Arabhavi in Belgaum
district of Karnataka. The experiment was laid in completely
randomized design with eight treatments comprised of Water
soaking for 24 hrs, GA3 250 ppm for 10 min., GA3 500 ppm
for 10 min., Vermiwash (1:5) for 24 hrs, Thiourea (1%) for 24
hrs, Cow urine(1:1) for 24 hrs, Cow dung slurry for 24 hrs and
Control with three replications. Observations were recorded
in respect of seedling height and number of leaves at 30, 60
and 90 days interval. Germination percentage was recorded.
The germination percentage was worked out after complete
germination, i.e., after stoppage of germination. It was
calculated by dividing total number of seeds sown with the
number of seeds germinated and was multiplied by 100. Fresh
and dry weights of seedlings were also recorded. Seedling
vigour was calculated based on the following formula (Bewley
and Black, 1982).
Vigour index I = Per cent germination × Length of seedling
Vigour index II = Per cent germination × Total dry weight of seedling
