This trial was made up of four provenances of Prosopis juliflora and two provenances of P. limensis and P. pallida. The provenances were a mixture of original introductions from South and Central America and landraces from Africa. The trial was established with a spacing of 4 x 4 metres in 1986 and assessed after 7 years in 1993. The assessment included survival, health and crown area.
The overall survival of the provenances was low, ranging from 10 to 40 %, but the mean height of trees in the largest provenances was 2.5 m. There were significant differences between provenances in all characters assessed, and the best choice seemed to be the landrace of P. juliflora from Burkina Faso.
