Because of their favourable hydrology, the small inland valleys of West Africa offer the possibility of sustainable increases in food crop production. A key component in any sustainable cropping system is the maintenance or restoration of soil fertility. This paper explores avenues for introducin...

Fitting soilimproving legumes into inland valley ricebased cropping systems in West Africa
On-farm trials were conducted at Kaduna in the northern Guinea savanna of Nigeria in 1996 and 1997. The objective was to investigate the residual effects of Mucuna and cowpea grown during the first 2-3months of the season on subsequent maize yields, to elicit farmers' feedback on these cropping s...

In the moist savanna zone with a 180 to 190 day growing period, early season cowpea immediately followed by a late season cereal crop can maximize the benefit of the legume to the cereal. Traditional cereal crops for this system are millet and sorghum but new early maize varieties can also be use...

Integrated soil management with leguminous cover crops was studied at two sites in the northern Guinea savanna zone of northern Nigeria, Kaduna (190 day growing season) and Bauchi (150 days). One-year planted fallows of mucuna, lablab, and crotalaria were compared with natural grass fallow and co...

Striga gesnerioides is a serious parasite of cowpea (Vigna unguiculata) on the Abomey plateau of southern Bénin. S. gesnerioides in southern Bénin has been characterized as a race that is different from those found in the dry savanna of West Africa. IITA breeding line IT93KZ-4-5-6-1-5 was used in...

Sustainable resource management is the critical agricultural research and development challenge in sub-Saharan Africa. The accumulated knowledge on soil management gathered over the last 10 years, combined with solid crop improvement and plant health research at farmers’ level, has brought us to ...
