In the Sahel of West Africa, the productivities of rangelands, croplands and livestock are inextricably linked. Cattle, sheep and goats graze rangelands and crop residues, and their manure/urine is used to fertilize crops. Rangelands provide important feeds during the manuring period, resulting i...

The influence of night grazing on feeding behavior, nutrition and performance of cattle was studied. Twenty-four steers weighing 367 kg (SD = 76) grazed either from 0900 to 1900 (day grazers), 2100 to 0700 (night grazers) or 0900 to 1900 and 2400 to 0400 (day-and-night grazers) during 13 weeks. F...

Achieving sustainable increases in agricultural production in sub-Saharan Africa is both a regional and a worldwide concern. High human and animal population densities in some areas have surpassed
land-carrying capacities causing environmental degradation and undermining the long-term stability o...

Cowpea is important for the provision of both grain for food and fodder for livestock but there is often a trade-off between productions of two. To better understanding influences on grain and fodder production, and how these may be influences on grain and fodder production, and two these may be ...

Animal manure is of vital importance in maintaining soil fertility in semiarid west Africa due to the low level of use of inorganic fertilizer. Using data from Niger however, it is shown that insufficient animals are available to provide the manure needed to sustain crop yields on a long-term bas...

Soil fertility maintenance and food crop production in semi-arid West Africa: Is reliance on manure a sustainable strategy?
Despite its vital role in supporting crop production, a key question that has often been posed is whether sufficient amounts of manure are available to permit adequate food production and improvement of soil quality on a long-term basis. While this question can be addressed at a regional, nationa...
