Recurrent selection under artificial S. hermonthica infestation has significantly reduced the number of emerged Striga plants and increased grain yield under Striga infestation in broad-based populations. These populations have been sources of varieties and inbred lines with consistently high lev...

Breeding maize for broad-based resistance to striga hermonthica
Maize (Zea mays) is an important crop for food, feed, and agroindustrial raw material produced primarily in the savannah but also in other agroecologies of West and Central Africa (WCA). Maize production in the savannah has been constrained by cultivation of inappropriate varieties, biotic and ab...

The parasitic flowering plants, Striga gesnerioides (wild.) Vatke and Alectra vogelii (Benth.), cause substantial yield reduction in cowpea in the dry savcannas of sub-Saharan Africa. Alectra is more prevalent in the Northern Guinea savanna and Southern Sudan Savanna of West Africa, as well as in...

The IITA in its research for sustainable soil fertility management has passed through several stages during which legume-based systems were always at the forefront. Alley cropping has N yields of more than 200 kg ha-1 with 50% N2 fixation. In the case of Mucuna cover cropping, the ecological bene...
