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...

Maize-cowpea intercropping as affected by nitrogen fertilization
Cowpea is an important food crop with high nutritional and socio-economical values in South Sudan. However, the lack of improved varieties is one of the main production constraints. This study was undertaken to assess the yield stability performance of improved cowpea genotypes across six environ...

The success of scaling out depends on a clear understanding of the factors that affect adoption of grain legumes and account for the dynamism of those factors across heterogeneous contexts of sub-Saharan Africa. We reviewed literature on adoption of grain legumes and other technologies in sub-Sah...

From best fit technologies to best fit scaling: incorporating and evaluating factors affecting the adoption of grain legumes in Sub-Saharan 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 this study, an intercropping experiment consisting of millet and groundnut was established at Dutse (Jigawa) and Minjibir (Kano) to compare the efficiencies of intercropping systems. Two intercropping systems (2:2 and 2:4; millet to groundnut ratio) were studied in terms of aggressivity, compe...

The large diversity of farms and farming systems in sub-Saharan Africa calls for agricultural improvement options that are adapted to the context in which smallholder farmers operate. The socio-ecological niche concept incorporates the agro-ecological, socio-cultural, economic and institutional d...
Smallholder farmers in the Guinea savanna practise cereal-legume intercropping to mitigate risks of crop failure in mono-cropping. The productivity of cereal-legume intercrops could be influenced by the spatial arrangement of the intercrops and the soil fertility status. Knowledge on the effect o...

This chapter discusses four species of grain legumes of the lowland tropics—that is, peanuts, pigeon peas, cowpeas, and mung beans. Various aspects of these species, such as plant improvement, plant protection, growth processes, and management are described. These four species made up 87% of both...
Field studies were conducted during the 2014 and 2015 wet seasons at Zaria in the northern Guinea savanna and at Iburu in the southern Guinea savanna of Nigeria to determine the productivity of maize– soybean intercropping system. There were four treatment combinations in the experiment: sole mai...
