Forty years old local mango trees were beheaded at 2 m height from ground level at monthly interval and the newly emerged shoots were grafted with three mango varieties viz.Kesar, Ratnaand Sindhu by wedge grafting. Significantly highest graft success at 30 days after grafting was obtained in May beheading and grafting in August (84.68%) while, it was the least in September beheading and December grafting (24.79%). Amongst the varieties used for grafting, cv. Kesar showed significantly higher grafting success (61.93%) as compared to cvs. Ratna (50.01%) and Sindhu (55.12%). Significantly highest grafting survival was noticed by the trees beheaded in November, followed by successive grafting in February (38.46%) while, the significantly least grafting survival was observed for trees beheaded in March followed by successive grafting in June (9.21%). Among the scion varieties, cv. Kesar recorded significantly superior grafting survival (26.47%) over the scion cv. Sindhu (21.93%) and Ratna (20.93%). However, mango stem borer was emerged as critical factor in mango top working. At 180 days after beheadingmost severe incidence of mango stem borer was noticed during summer to rainy season (25.33 to 74.66%). Thus, beheading of mango tree for top working has been recommended during specific period i.e. November to January followed by wedge grafting with scion cv. Kesar during February to April.
