Different types of problems are to be tackled by West African breeders to make important improvement on the West African varieties. The most important are those that directly concern the morphology and physiology of the rice varieties. The first major change should be the reduction in height, and...

The grain yields in the no-tillage plots were equivalent to those of conventionally plowed treatments. No-tillage treatments had higher organic matter content and, by controlling soil erosion, the silt and clay content than the plowed plots. The water holding capacity and moisture release charact...
