Orthogonal contrasts indicated dierences among windbreak species and the control for stover dry matter and survival in 1993.
Plots without any windbreak served as the control.
The porosity in-uenced drag and wind speed leeward of the windbreaks drastically.
Furthermore, alternatives to windbreaks for wind erosion control (for example, soil mulching) are needed for areas where farmers hesitate to adopt windbreaks.
Each experiment was bordered by two rows of cowpea and two rows of maize as a windbreak to aid the collection of abscised leaves.
The survival of millet in 1993 was generally higher than in 1992, but dierences among windbreak species were small.
No interaction between windbreak species and soil mulch was detected, except for millet survival in 1992.
A mulch application reduced overall soil -ux by 51% in 1991, 49% in 1992 and 67% in 1993 across all windbreaks and the control.
