A.Khan 3 2001 1 3 Macropropagation of guava (Psidium guajava L.) cv. Sufeda by T-grafting and Chip budding was investigated 6 times beginning April 15 at monthly interval upto September, 15. Scionwood of cv. sufeda was prepared on the tree by excising 10 - 15 cm terminal growth 20 days prior operation. These were grafted/budded on to land race guava root-stock. Maximum sprouting of 93.33% was produced in T-grafting on July, 15 followed by chip budding (86.7%) on June, 15. After a year`s shoot length (24.0 cm) was prominent in chip budding and shoter one (17.94 cm) in T-grafting. The highest success rate of (86.7%) was obtained in T-grafting on July, 15. Chip budding also gave better survival of budded plants (80.00%) on June, 15. The interaction between propagation methods x months of operation was found non-significant. T-grafting had given best survival of propagated guava plants on July, 15 and August, 15 and chip budding on June, 15. T-grafting has expressed superiority over chip budding in the present experiment but from economic point of view chip budding is superior because, it is easy, quick and use of one bud instead of whole shoot in the operation.
