The better germination per cent of mango (Mangifera indica L.) stones is the criterion and strong base for successful grafts hence to enhance the germination, growth and graft parameters different pre-soaking treatments in mango was carried out. Where Mango stones of Nekkare were obtained from one single lot from a processing unit and were used. The stones were pre-soaked viz., Control, GA3, Silicylic acid, Vermiwash and Cow urine of different concentrations. The different pre-soaking treatments of stones revealed that all the growth parameters were positively influenced and resulted in early germination. However, among the treatments the stones pre-treated with GA3 500 ppm for 10 minutes recorded significantly lower number of days taken for initiation and completion of germination, maximum germination percentage, root stock height, root stock diameter, number of leaves/root stock, highest graft success, graft survival per cent and germination index were significantly higher compared to control. Similarly, at 30, 60 and 90 days of grafting GA3-500 ppm gave significant maximum graft height, graft diameter and more number of leaves per graft. Maximum graft success after three months of grafting was recorded with GA3-500ppm (81.72 %) followed by GA3-250 ppm (71.92 %) and Si6ml/l (67.09 %). Significant maximum graft survivability was recorded with GA3-500 ppm (76.11 %) and GA3-250 ppm (72.29 %) and less was recorded from cow urine at 50 per cent treatment.
