Tuber yields of yam (Dioscorea spp.), a main staple food in West Africa, are steadily declining per unit area, an incidence for which decreasing soil fertility due to increasing land pressure is largely blamed. Recent studies demonstrated the association of a plethora of arbuscular mycorrhizal fu...

A new arbuscular mycorrhizal fungus was isolated from the Southern Guinea savanna in Benin, which represents a tree-rich savanna in the transi-tion between the tropical atlantic rainforests and grass-rich savannas in sub-Saharan West Africa. The fungus was propagated in bait cultures and monospor...

Striga hermonthica is a serious parasite of cereals in most of the semi-arid savanna zone of West Africa, causing substantial yield loss. It has been observed that some soybean cultivars are capable of stimulating germination of S. hermonthica seed, which would reduce the seed bank in the soil. T...

The rapid decline of soil fertility of cultivated lands in the sub-Saharan savannas of West Africa is considered to be the main cause of the increasingly severeconstraints of food production. The soils in this tropical area are highly fragile, and crop yields are limited bycharacteristically low ...

Yam (Dioscoreaspp.) is a tuberous staple foodcrop of major importance in the sub-Saharan savannas ofWest Africa. Optimal yields commonly are obtained only inthe first year following slash-and-burn in the shifting cul-tivation systems. It appears that the yield decline in sub-sequent years is not ...
