EVALUATION AND PERFORMANCE OF MANGO TREE PROPAGATED BY WHIP-GRAFTING TECHNIQUE IN SEMI ARID REGION OF BORNO STATE

Experiment was conducted at Imam Malik Plant Nursery Unit of Maiduguri, Borno State. During the period of June 2008-December 2009, to investigate the use of whip-grafting technique for mango propagation, evaluation and performance of Mango propagated were determined using the Scion which is detached from the parent tree. The treatments were rootstock diameters of 1.5, 1.5 to 0.5 cm; Scion hardening methods in which the leaves were either removed or trimmed to half leaves, scion length of 8-9 or 15-16 cm, glasshouse and nursery shed conditions and two cultivars, namely Bokorram and Man lawan. The most viable scions with the highest number of successful graft were obtained when scions in which all the leaves were removed, were grafted on rootstock 0.5 diameter. There was no significant difference between two mango cultivars, but Manlawan tended to have higher values
