bullet3 Trial 5: Provenance trial of Acacia senegal

This trial was made up of 6 provenances of Acacia senegal. The trial was established in 1988 with a spacing of 4 x 4 metres at Djibo in Burkina Faso. The assessment took place five years later in 1993, and included a number of vegetative and growth characters. Gum production was not measured. The provenances included a selection of seedlots from the Sahel (Burkina Faso, Niger, Mali and Sudan) and one provenance from Rajasthan in India.

The differences between provenances were highly significant for all characters except number of stems. In particular, the provenance from India had a very poor performance, but even when this seedlot was excluded there were significant differences (in height and crown area) between the remaining provenances from Africa. Provenances from the Sahelian phytogeographical zone had a faster height growth than the two provenances from the Sudanian zone. A multivariate analysis confirmed that the provenance from India was clearly separated from the other seedlots. The best provenance had a dry weight production of approximately 1.4 t ha-1y-1.
