Two promising methods including modified bark grafting and cleft grafting at two times (early April and mid April) were further evaluated during 2001- 2006, in terms of grafting percentage and subsequent impact on growth and fruiting using a completely randomized block design. The modified bark grafting on main branches in the mid April showed the highest grafting success and survival percentage (76 - 93%). The number of nut, kernel color and weight was increased significantly in the top worked shoots compared to the non-top worked shoots (p M3 10.18869/acadpub.jcpp.5.15.1 ER -
