Abstract : The effects of grafting date (15 April, May, June, July, August or September) and method (veneer grafting, cleft grafting and modified cleft grafting), and their interaction, on the propagation of mango cultivars Amrapali and Gopalbhog were studied. The survival and growth of scion and rootstock were evaluated at 120 days after grafting. In terms of grafting date, the greatest survival (87.19%), scion growth (19.34 cm), number of shoots (2.86 per graft) and number of leaves (26.87 per graft) were obtained with grafting on 15 June. Rootstock growth was most pronounced (44.57 cm) with grafting on 15 April. Among the cultivars, higher survival (66.13%) was recorded for Amrapali. Scion growth (12.31 cm) and number of leaves (19.60) were greater in Gopalbhog. With regard to the grafting method, modified cleft grafting recorded the greatest survival (68.76%), rootstock (2.74 cm) and scion (15.20 cm) growth, and number of shoots (2.13) and leaves (21.55). The analysis of interaction effects revealed that graft survival was highest (96.07%) in Amrapali grafted on 15 June by modified cleft grafting. Rootstock growth (5.32 cm) was superior in Gopalbhog grafted on 15 April by modified cleft grafting. Scion growth (24.13 cm) and number of leaves (31.93) were highest in Gopalbhog grafted on 15 June by modified cleft grafting. Amrapali grafted on 15 May by modified cleft grafting had the highest number of shoots (3.18).
