Abstract : Propagation studies in mango with epicotyl grafting were carried out with 7 growth media. Six sub-treatments included grafting on 5, 7, 9, 11, 13 and 15-day-old rootstocks. The highest sprouting of graft scion was recorded in soil+FYM+sand, followed by soil+leaf mold. Sprouting was significantly higher with the use of 7-day-old rootstock for grafting, followed by 9- and 5-day-old rootstock. The highest survival was observed with 7-day-old stock, the survival rate decreased when the age of the stock increased to 15 days. The graft survival was better in soil+FYM+sand, followed by soil+FYM, after 4 months of grafting. The survival percentage was higher in transplanted grafts than those grafted in situ in polybags. Vegetative growth, i.e. sprout length and sprout diameter, was highest in plants grafted on 7-day-old rootstock, followed by 9 and 11-day-old rootstocks.
