主　　题：Acacia polyacantha date of tapping gum yield Kakamut South Kordofan tapping tools 

摘      要：A study was conducted in South Kordofan, Sudan to determine the effect of tapping, tapping tools and date of tapping on the gum yield of Acacia polyacantha. A two-factor experiment was conducted for two seasons in 2008-2009. One location was used for two seasons and two locations for one season. The first factor （4 levels） was the tools of tapping： Makmak, Farrar, and Sonki, and the control which was not tapped. The second factor （2 levels） was the date of tapping that comprises mid October and mid November. These treatments were arranged in Randomaized Complete Block Design and replicated three times. Gum yield （g/tree and g/ picking） was recorded for five pickings. Economic analysis was done using the partial budget technique. The results showed highly significant （p 〈 0.01） differences on gum yield （g/picking and g/tree）. The results indicated that the process of tapping increases gum production by 88.4% and 79.8% compared with un-tapped trees, respectively. The date of tapping has no significant effect on gum yield （g/tree and g/picking） of A. polyacantha. Tapping of the tree with Makmak in mid- November was found to be economically beneficial compared to using the other tools and the control. These results could identify a new source of income for the poor farmers in South Kordofan mainly because of the wild occurrence of Kakamut as a potential gum producing tree species grown naturally in the area.
