Note générale :	Surface mulching with crop residue at the rate of 4 to 6 tons/ha decrease soil temperature and maintains favorable soil structure through enhanced biological activity. Continuous surface cover can be maintained by growing and least competitive cover crops or by the use of crop residue through rotation and tillage techniques. Mulch tillage such as minimum tillage based on the zonal tillage concept of maintaining crop residue in the inter-row zone and simultaneously providing a good seed bed meets most soil management requirements for many upland crops. Yields of maize, cowpeas, pigeon peas, soybeans and sweet potatoes on mulch tillage plots equal yields from plowed ploto. A the same time the soil erosion is minimal and soil structure is maintained by more intensive soil flora fauna activity.
