Genomic tools in cowpea breeding programs: status and perspectives
Cowpea is one of the most important grain legumes in sub-Saharan Africa (SSA). It provides strong support to the livelihood of small-scale farmers through its contributions to their nutritional security, income generation ...
Bradyrhizobium inoculants enhance grain yields of soybean and cowpea in northern Ghana
This study evaluated the symbiotic effectiveness and economic evaluation of Rhizobium
inoculants with the objective of recommending the most effective inoculant strain
for soybean and cowpea production in Northern Ghana. ...
Identification of new sources of resistance to Striga gesnerioides in cowpea Vigna unguiculata accessions
The parasitic weed, Striga gesnerioides, is a major threat to cowpea productivity throughout the savannas of West and Central Africa. The
identification of sources of S. gesnerioides resistance and their incorporation in ...
Genetic diversity of physical, nutritional and functional properties of cowpea grain and relationships among the traits
Cowpea is traditionally important as an affordable source of protein and minerals and of cash
income in sub-Saharan Africa, especially for small-scale farmers who have limited options for
food and cash crops. The development ...
Evaluation of early maturing cowpea (Vigna unguiculata) germplasm for variation in phosphorus use efficiency and biological nitrogen fixation potential with indigenous rhizobial populations
Cowpea genotypes that efficiently utilize phosphorus (P) with high potential for biological nitrogen (N) fixation (BNF) are vital to sustainable cropping systems in West Africa. A total of 175 early maturing cowpea genotypes ...
Incidence and diversity of viruses in cowpeas and weeds in the unmanaged farming systems of savanna zones in Nigeria
Fields surveys were conducted to assess the incidence of commonly known legume viruses on cowpeas and weed hosts within and around the cowpeas farms in nine locations across the three agro-ecological zones of Nigeria. Of ...
Volatiles from Maruca vitrata (Lepidoptera, Crambidae) host plants influence olfactory responses of the parasitoid Therophilus javanus (Hymenoptera, Braconidae, Agathidinae)
Plants damaged by herbivores are known to release odors attracting parasitoids. However, there is currently no information how leguminous plants damaged by the pod borer Maruca vitrata attract the exotic larval parasitoid ...
Effects of plant density on the performance of cowpea in Nigerian Savannas
Grain yields of cowpea [Vigna unguiculata (L.) Walp.] in the Nigerian savannas are low even with the
cultivation of improved varieties. The recommended spacing for cowpea is 75 × 20 cm with two
seeds planted per stand. ...
Understanding market participation choices and decisions of maize and cowpea farmers in northern Nigeria
Alleviating poverty and reducing food insecurity have received close critical attention from many researchers in subSaharan Africa. Farmers' participation in agricultural markets has been seen as a potent strategy for i ...
