Soils of the moist savanna of West Africa are poor in
nitrogen; the natural fallow regeneration time has shortened; fertilizer costs
and scarcity makes nitrogen (N) fertilizer input inadequate; and crop yields
are low. In the region, lablab (Lablab purpureus L., sweet also known as
Dolichos labla...

A field study was conducted to determine the rate of genetic improvement in grain and fodder yields and associated agronomic and physiological changes of determinate and semideterminate cowpea [Vigna unguiculata (L.) Walp.] genotypes developed in the Nigerian Sudan savannas in 1974 to 2004. Resul...
