Three gregarious, endoparasitic braconids, a Kenyan strain of Cotesia sesamiae, and the exotic Cotesia flavipes and Cotesia chilonis were imported into Benin as candidates for biological control of stem- and cob borers of maize and stemborers of millet. Host acceptability and host suitability of ...

Agricultural intensification involving greater crop–livestock interactions and integration is emerging as the most promising strategy for improving agricultural production and productivity in much of Sub-Sahara Africa. In West Africa, where this process is at various stages of evolution, 559 far...


Okike, I.Jabbar, M.A.Manyong, Victor M.Smith, Jimmy W.Ehui, Simeon K.[Factors affecting farm-specific economic efficiency in the West African savannahs.]Factors affecting farm-specific economic efficiency in the West African savannahs.

Agricultural intensification in West Africa is at an early stage and the process is taking place through various pathways. Population pressure and market access are generally considered as major factors driving intensification and crop-livestock interaction. In this paper both ecology and economi...

Inadequate nutrition and helminthiasis were among the important constraints to smallscale dairy production identified in a 4-country survey among traditional dairy producers. Consequently, multi-locational trials to study helminth control and supplementary feeding to grazing cattle are being impl...

Rapid growth of the human and livestock populations in sub-Saharan Africa is creating unprecedented increases in food and feed demands. These population pressures on a fixed landbases are likely to promote severe competition for resources and drive agriculture progressively towards intensificatio...

A study was conducted in the humid-forest, forest-savanna, and Guinea savanna zones of West Africa from 1993 to 1999 to examine the effect of managing crop residues from cereal-legume cropping systems for mulch and fodder for sheeIncreasing the proportion of total crop residues produced from a un...

An experiment was conducted on an Ultisol at the International Institute of Tropical Agriculture (IITA) High Rainfall Station, Onne, in the humid forest zone of south-eastern Nigeria. The objective of the study was to define groups of multipurpose trees using multiple variables to select material...

Harvests were made at the end of the main (April-August) and minor (September-November) wet, and dry (December-March) seasons for two years. Dry season edible forage samples were analyzed for concentrations of crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (NDF), acid det...

Two experiments were conducted using dried leaves of Alchornea cordifolia, Ficus capensis, Manniophytum fulvum and Albizza niopoides. In Experiment 1, dry matter (DM) degradation characteristics were investigated using the in sacco nylon bag technique in West African Dwarf (WAD) sheep, WAD goats ...
