Planting of what we called ‘dry season’ cassava is done mid-September after early maize in association or not with cover crops (finger millet and sunnhemp). A chisel plough is used to open the planting line of cassava. The establishment is easier than that at the beginning of the season (March to May) with less comptetion with weeds and much better establishment of cassava in a context of climate uncertainties. Cassava will then be grown from 10 to 18 months depending of the market commodities and cash requirements of the smallholder farmers. Appropriate-scale machinery with direct planter of cassava is of paramount importance offsetting the scarcity of labor force and moving to appropriate soil and crop management (no ploughing and no ridging).

We cancel the soil preparation with disk plough and ridge. We only use a chisel plough for cassava planting from March to April depending of the rainfall pattern. We are able to preserve the soil resources avoiding the soil erosion and a high rate of soil organic matter mineralization. Cassava should also be conducted under rotational sequence with maize under no-till cropping systems.
