In an on-station agroforestry experiment conducted in south-west Niger, the effects of seven windbreak species and of a soil mulch made from crop residue on wind erosion and pearl millet (Pennisetum glaucum) production were monitored. Within a distance of 20 m, strips of the perennial grass, Andropogon gayanus, reduced total annual soil flux by 6-55% and hedges of Bauhinia rufescens 2 m in height reduced soil flux by 47-77% compared with unsheltered control plots. No significant overall windbreak effect on millet stover and grain yields was found. In contrast, erosion reduction and yield increases due to mulch application ( 2 t millet stover/ha) were highly significant. It is concluded that soil mulch is a promising alternative to complex windbreak-millet cropping systems in regions where direct economic benefits for farmers are not ensured by windbreaks
