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 ...
Screening wild vigna species and cowpea (Vigna unguiculata) landraces for sources of resistance to striga gesnerioides
This chapter presents the results of a study conducted on the experimental field of the International Institute of Tropical Agriculture (IITA) in Minjibir, Kano State, Nigeria, during the planting seasons of 2012 and 2013 ...
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 ...
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 ...
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. ...
