This preliminary study is being carried out in Adwari Sub County,
Otuke District (Northern Uganda). The aim of the study is to
adapt an appropriate grafting technique for propagating
Vitellaria paradoxa in Uganda. Two grafting techniques (splice
and top wedge) have been tested on varying ages of
V.paradoxa wild seedlings and saplings. The results so far
indicate that grafting methods had no significant (P =0.423)
effect on scion survival before 16 weeks after grafting.
However, the splice grafting method had 14.3 % and top wedge
grafting method had 0% scions’ survival up to 5½ weeks. The
age of rootstock had no significant effect on grafting success
(P =0.423). Grafts on seedlings had the highest rate of survival
of scions at a decreasing rate than saplings up to 5½ weeks
after grafting. Further experiments are still needed to determine
with certainty whether the response of V. paradoxa grafts to
scions survival can or can not be influenced by both grafting
methods and ages of the wild rootstock.
