It is a preferred food security crop among smallholder farmers, because it can tolerate drought, low soil fertility and its production requires minimum external inputs. Various constraints have been shown to affect the wid...
The results are presented of a project to promote integrated Striga control (ISC) technologies to farmers in the Guinea savanna of northern Nigeria. Extension agents used a participatory research and extension approach (PREA) to encourage farmers to test and adopt ISC technologies. Over a 2-year ...
Forage plant evaluation is carried out by many institutions throughout sub-Saharan Africa. However, the approach adopted at various locations varies. This manual outlines standard evaluation methodology, which will enable researchers throughout the region to obtain meaningful results from their f...
Speargrass is a serious weed in many farming systems of West Africa. Participatory research and extension approaches were used to promote farmer testing of alternative speargrass management options in yam, cassava and soybean in Nigeria. Treatments were paired plots with a farmers' control and at...
Traditional shifting cultivation systems can no longer be sustained in West Africa because of rapid increases in human and livestock populations. Short-duration, improved fallows are among the alternative land-management strategies that have evolved. This paper reviews how velvetbean or mucuna (M...
Studies of potassium (K) fixation in the soil were conducted by evaluating the effect of applied K on the extractability of K with time. A series of five K-sorption treatment solutions, 0.11, 0.22, 0.45, 0.90, and 1.80 cmol/kg were prepared and applied as potassium chloride (KC1) to three sets of...
