The concentrations ofP, N, K, Mg, Cain cowpea (Vigna unguiculata (L.) Walp.) roots and shoots were assessed at 45 Days After Planting (DAP) in inoculated and uninoculated plants at sowing with rhizobia and Arbuscular-Mycorrhizal Fungi (AMF). Those of harvested seeds from inoculated and uninoculat...

Plant architecture and N fertilizer may limit the performance of intercropped maize (Zea mays L.) and cowpea [Vigna unguiculata (L.) Walpers] cultivars. This paper describes an experiment in which cultivars of maize and cowpea were intercropped and fertilized with varying rates of N. The cowpea c...

Aphid (Aphis craccivora Koch) is a major pest of cowpea [Vigna unguiculata (L.) Walp.] particularly in the drier regions of the tropics. It causes direct damage by feeding on the plants and also transmits viruses. Several sources of resistance to cowpea aphid have been identified and efforts are ...

Cowpea is seed propagated and when mature seeds are properly dried they could remain viable over a period of time depending on the genotype and storage conditions. Due to heat and dry conditions seeds of cultivated cowpea that remain in the fields after harvest usually do not retain viability for...

Cowpea [Vigna unguiculata (L.) Walp] exhibits a considerable variation in leaf shape. Although cowpea is mostly utilized as a dry grain and animal fodder crop, cowpea leaves are also used as a high-protein pot herb in many countries of Africa.

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. This corresponds to plant population of 133333 plants ha−1, which may not be s...

In most parts of West Africa, poverty contributes immensely to poor fertilizer adoption by smallholder farmers. Fertilizer adoption could be improved with micro-dosing technology. A socio-economic survey was conducted in the semi-deciduous forest zone of Ghana to assess the extent of fertilizer u...
