Abstract : An experiment was conducted during 2006-07, in Karnataka, India, to investigate the effect of pre-soaking treatments on the germination, growth and graft-take in mango. The treatments consisted of water soaking (12 hours), 1% KNO3 (10 min), 100 ppm GA3 (10 min), cow dung (12 hours), cow urine (12 hours), Amrit pani (3% for 3 hours) and Panchagavya (3% for 12 hours). All the treatments promoted significantly earlier germination when compared with the control. The stones pre-treated with 3% Panchagavya recorded significantly lower number of days for the initiation of germination (12.25 days) and completion of germination (46.18 days) as well as maximum germination percentage (75.22%), rootstock diameter (7.35 mm), number of leaves (14.77), graft success (76.15%), graft survival percentage (92.04%), sprout height (5.96 cm) and number of leaves per graft (17.80). GA3 at 100 ppm showed the highest germination index (4.46) and rootstock height (36.43 cm), which was at par with KNO3 and water soaking.
