Low inherent soil fertility in the highly weathered and leached soils largely accounts for low and unsustained crop yields in most African countries. But in particular, the major nutrients, nitrogen (N) and phosphorus (P), are commonly deficient in these soils. This scenario of nutrient depletion...

This study examined the influence of organic residue quality and N fertilizer on aggregate-associated SOM in maize cropping systems of southern Ghana. Six residue treatments of differing quality (Crotalaria juncea, Leucaena leucocephala, maize stover, sawdust, cattle manure and a control with ...

Nutrient depletion is a major constraint to crop production for moist savanna soils, and inputs of nutrients are required to overcome this constraint. The impact of sole and combined applications of organic inputs (OIs) [fresh tree prunings, Pueraria phaseoloides (Roxb.) Benth. residues, and manu...

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...

Maíz de alta calidad de proteína (Quality Protein Maize, en inglés, QPM), con el doble de triptófano y lisina que el maíz convencional, ha mejorado el estado nutricional de niños severamente desnutridos. Su impacto en el crecimiento y morbilidad de niños con desnutrición leve o moderado fue estud...

Objective. Ten typical recipes from southwestern Colombia were evaluated at CIAT in Palmira, Colombia between 2008 and 2009. Material and Methods. The recipes were prepared in a traditional manner, using quality protein maize (QPM, with more tryptophan and lysine) or common maize (CM); each of th...
