Smallholder farmers in East-Africa commonly intercrop maize (Zea mays L.) with grain legumes to maximize utilisation of land and labour, and attain larger crop yields. Conventionally, one legume line is intercropped between each pair of maize lines. This study evaluated the potential of a modifie...

Common bean and soybean yield poorly on smallholder farms in Rwanda. We evaluated the benefits of inoculation combined with P fertilizer and manure on yields of common bean and soybean in three agro-ecological zones (AEZs), and their residual effects on a subsequent maize crop. In the first seaso...

Crop response, tree biomass production and changes in soil fertility characteristics were monitored in a long-term (1986–2002) alley-cropping trial in Ibadan, Nigeria. The systems included two alley cropping systems with Leucaena leucocephala and Senna siamea on the one hand and a control (no-tre...

De nombreux pays en Afrique ont intégré l’utilisation des engrais, la gestion de la fertilité des sols et les intrants agricoles dans leurs contributions déterminées au niveau national à l’Accord sur le climat de Paris. Bien que les engrais azotés (N) contribuent dans une large mesure aux émissi...

Establishing balanced nutrient requirements for maize (Zea mays L.) in the Northern Nigerian Savanna is paramount to develop site-specific fertilizer recommendations to increase maize yield, profits of farmers and avoid negative environmental impacts of fertilizer use. The model QUEFTS (QUantitat...

A synthesis of results from the savanna zone of West Africa suggests that cowpea rotation can be considered to be an effective resource management technology in cereal-based systems. Part of the N requirement of cereal crops can be satisfied by cowpea crop rotation. Furthermore, benefits of cowpe...

Mucuna pruriens and Lablab purpureus can immediately benefit from rock phosphate (RP), but as both herbaceous legumes have only limited economic value, these benefits are only meaningful if yields of a subsequent maize crop are improved. The impact of RP application to Mucuna and Lablab on grain ...

Data from the derived savanna zone in southern Benin indicated that some intensive cropping systems (maize/Cajanus and maize/Mucuna relays; maize/cotton with Senna siamea hedgerows) returned about 12 Mg DM ha-1 year-1 of plant biomass to the soil. This compared favorably with the 8 Mg DM ha-1 yea...

The fate of 15N-labeled plant residues from different cover-cropping systems and labeled inorganic N fertilizer in the organic, soil mineral, microbial biomass and soil organic matter (SOM) particle-size fractions was investigated in a sandy Lixisol. Plant residues were from mucuna (legume), labl...
