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 ...
Capacity Building
In collaboration with partners, several training events were conducted to improve the skills and knowledge of farmers and extension agents in improved crop production practices and symbiotic nitrogen fixation technologies. ...
Effect of phosphorus (P) application on nutrient uptake, biomass, pod and seed formation in cowpea (Vigna unguiculata (L.) Walp])
Phosphorous (P) deficiency is a serious problem which limits the
productivity of cowpea in sub-Saharan Africa.
• P deficiency affects negatively the formation of nodule (1, 2) and the
symbiotic fixation of N2 by limiting ...
From best fit technologies to best fit scaling: incorporating and evaluating factors affecting the adoption of grain legumes in Sub-Saharan Africa.
Sub-Saharan Africa is characterised by diverse and heterogeneous environments
(World Bank, 2009), languages, cultures, institutions and histories (Hopkins, 2009)
and farming systems (Giller et al., 2011b; Tittonell et al., ...
Opportunities for sustainable legume business development: an experience from the public-private partnership progresses in south Eastern Ethiopia.
Chickpea is widely grown food grain legume in rotation with cereals and is an important source of food and income. The chickpea value chain comprise of different actors at different functional levels. Evidence indicates ...
Biological and biochemical characterization of isolates of Helicoverpa armigera Nucleopolyhedrovirus (HaNPV) from different geographic locations of India
Six strains of HaNPV collected from different places of India were compared for their biological and biochemical characteristics. Based on the bioassay tests against second and third instar larvae of Helicoverpa armigera ...
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. ...
Accelerating Knowledge Sharing on Global Dryland Solutions For systems transformation
Accelerating knowledge sharing across the global drylands on solutions for dryland agriculture properly described for outscaling (conditions for success, readiness for scaling) and assessed for multiple benefits
Screening cowpea germplasm (cultivated and wild relatives) for aphid resistance
A total set of 376 entries including 374 mini-core accessions, 1 resistant check (TVu801) and 1 susceptible check (TVx 3236) were evaluated in screening cages at Kano and screen house at Cotonou for resistance to cowpea ...
Local normative climate shaping agency and agricultural livelihoods in sub-Saharan Africa
We introduce the concept of local normative climate to improve understanding of communitylevel social processes that shape women’s and men’s sense of agency and capacities for taking
important decisions, including in their ...
