In 1988 a field survey was conducted on soybean (Glycine max) production trials at Ayepe in Nigeria. The survey investigated yield variability, fertilizer requirements and economic returns among small farmers. It revealed that the soybean yield was low (524 kg/ha), while yield variability was ext...

Considerable progress has been made in breeding improved cowpea varieties in the last five years. The major breeding objectives were to develop high yielding cowpea varieties for sole cropping as well as intercropping with acceptable seed types and resistance to major diseases, insect pests, nema...

In cover cropping systems in the tropics with herbaceous legumes, plant residues are expected to supply nitrogen (N) to non-legume crops during decomposition. Field experiments were carried out to (i) determine the effects of residue quality on decomposition and N release patterns of selected pla...

Reliable estimates of symbiotically fixed N2 in herbaceous legumes are important in order to determine their role in maintaining or improving N levels in tropical low-external-input farming systems. We have studied the effects of different management systems on the suitability of two non-N2-fixin...

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...

Cowpea (Vigna unguiculata[L.] Walp.) is an important grain legume in the semi- arid zone of West Africa as it is a major source of dietary protein for the people. It is usually grown as an intercrop with the major cereals, namely millet and sorghum. Despite its importance, its yields are very low...

With the low input of fertilizers into African farming systems, it is necessary to harness biological nitrogen fixation to its fullest extent. The greatest potential, at least in the short term, lies in nitrogen fixation in grain and pasture legumes and in nitrogen-fixing trees. To maximise nitro...

This paper presents a framework for economic analysis of smallholder agroforestry systems in the Sahel of West Africa. The approach developed makes use of the technique of investment analysis, but incorporates into it a framework that recognizes the special features of some agroforestry costs and...
