Assessing the Natural Regeneration Potential of Senegalia senegal by Rejection in Chad: Implications for Sustainable Management

Abstract

The study of the potential of natural regeneration assisted by weaning of white gum was carried out in Mandalia, a locality located about 50 km from N'Djamena and its surrounding area. Inductions of shoots by weaning were carried out at two sites, one a Senegalia senegal Park and the other a grazing area. In the S. senegal parks, most of the shoots were underground. On the other hand, on the grazing land, most of the shoots were stump shoots. There was no significant difference between the number of shoots in the S. senegal park and in the grazing land. The survival rate of underground shoots at weaning showed a low value of less than 25%. In the Acacia Park, the correlation between survival and shoot size was 80.28%. However, in the grazing area, the survival rate was 50.69%. These results show that the site does not significantly influence the fate of the weaned underground discharge. It is clear from this study that a sustainable management plan for S. senegal is urgently required. To this end, studies on varietal selection and domestication of S. senegal should be undertaken as soon as possible. Raising farmers' awareness of the need to protect offshoots in agrosystems and promoting assisted natural regeneration in agrosystems would also enable them to be conserved by local populations and gradually domesticated in the short term.
