Abstract
The present investigation to know the effect of IBA on rooting and sprouting in
basal and mid cuttings of pomegranate (Punica granatum L) was carried out during year
2010-2011 at the Department of Horticulture, Gandhi Krishi Vignana Kendra (GKVK),
University of Agricultural Sciences, Bangalore, Karnataka, India.
Observation on the vegetative parameters are significantly higher with the
treatment containing 1000 ppm IBA concentration (T1) in basal cuttings with regard to
days taken for sprouting (14.33 days), number of sprouting per cutting (6.18), length of
shoot (7.59 cm), number of leaves (22.30), number of roots (20.46), length of longest
roots (6.41cm) as well as survival percentage (82.36 %) as compared to control (18.00
days), number of sprouting per cutting (3.81), length of shoot (5.21 cm), number of
leaves (16.26), number of roots (17.16), length of longest roots (4.14cm) and survival
percentage (46.49 %) respectively).
Among the cuttings, basal cuttings recorded statistically significant difference in
shoot and root parameters from first to seventh week after planting than mid cuttings.
Among the different growth regulator concentrations, IBA @ 1000 ppm induced better
root and shoot from first to seventh week against control.
The maximum net profit (Rs.118.75) could be obtained in same concentration
from 75 cuttings.
