Farmer harvesting maize. You can also observe the cover crop (pigeon pea) inter-cropped with maize. The main technical principles of conservation agriculture are to maintain a soil cover, no soil disturbance, and enhance the use of a large diversity of species (association, rotation, inter-cropping).
Pigeon pea is one of the most suitable cover crops to ecologically intensify maize cultivation under CA management. On shallow soils and to avoid possible competition for water, pigeon pea is sown 15 days after maize. After harvesting maize in November, the pigeon pea continues to grow crossing the dry season, suppressing weeds and improving soil structure and fertility. The grain could be harvested for sale or animal feed.
