The green leaves make a useful mulch. The press cake left after oil extraction from the seeds can be used as a soil conditioner or as fertilizer. The tree provides semi-shade, useful in intercropping systems where intense direct sunlight can damage crops. For livestock, branches are occasionally cut for feeding camels and cattle.
