Some methodologies, including examples, for developing bean var. specifically adapted to intercropping with maize are considered. Since every breeding program has to contend with genotype x environment interactions, decisions have to be made regarding the locations for breeding nurseries, the con...

This article demonstrates how conservation agriculture impacts smallholder farmers' livelihoods in Mozambique through increased crop productivity and yields, using primary data on smallholder farmers practicing conservation agriculture and others not using this technology from Nhanguo, Pumbuto, a...

The decline of soil organic matter (SOM) and its associated fertility is one of the most important constraints to enhanced crop productivity in sub-Saharan Africa. Integrated soil fertility management recognizes the potential benefits of the combined use of organic residue and mineral fertilizer ...

Promiscuous soyabean varieties have potential to contribute significantly to income generation, food security and soil N budgets on smallholder farms. One of the major factors limiting this potential is farmers preference to allocate nutrient resources to food security cereal crops on the most f...

Soil carbon distribution with depth, stable carbon isotope ratios in soil organic matter and their changes as a consequence of the presence of legume were studied in three 12-year-old tropical pastures (grass alone Brachiaria decumbens (C4), legume alone Pueraria phaseoloides (C3) and grass + l...

Acacia senegal, an important leguminous tree in arid and semi-arid environments, has shown promise as a multipurpose species, including gum production and soil fertility improvement, linked with N2-fixation capabilities. Of particular interest are ontogenetic and edaphic effects on A. senegal per...
