The effects of leucaena hedgerows, mulching with leucaena foliage (0.50 and 100 percent of harvested foliage), cowpea intercropping and addition of dairy cattle slurry (55 t ha-1 per maize crop) on the yield of maize from a sandy soil were assessed. The four-year results from five maize crops are...

Outlines a re-evaluation and a re-calculation of recently published hypothesis concerning the potential impact of alley farming on maize yields. Gives modifications and analysis based on the alley farming research of the International Livestock Center for Africa's (ILCA) Humid Zone Programme in N...

Evaluates alley farming models with small ruminants based on field and experimental data from southwest Nigeria, and compares them to basic alley cropping and to fallow systems. Describes the basic fallow model, the basic alley cropping model without animals, the alley farming model with goats, a...

Reports concentrations of primary and secondary nutrients in the dry matter that were harvested at various times and the removal of the nutrients from an upland soil in the Ethiopian highland in part III. Part IV deals with the concentration and uptake of Na, Mn, Cu, Zn and Fe from the dry matter...

A virus with filamentous particles approximately 750 nm long was isolated from African oil palm (Elaeis guineensis) with `chlorotic ring' leaf symptoms in south-western Colombia. The virus was mechanically transmitted from oil palm to brachiaria, maize, sorghum, and sugarcane (Gramineae) but not ...

One experiment was completed with 56 weanling Duroc x Landrace x Yorkshire swine and two with weanling Sprague-Dawley rats to determine the nutritive value of Colombian floury-2 corn in comparison with that of Colombian opaque-2 and Colombian common corn. In both rats and swine Colombian floury-2...

Nitrogen (N) has been gradually depleted from West African soils and now poses serious threats to food production. Many ways of increasing N supply (e.g. judicious use of inorganic fertilizers and nitrogen-fixing plants) have been tried in West African farming systems. Herbaceous and woody legume...
