Highlights the interactions between agronomy and economics in developing forage production techniques for the two main land-use situations in the subhumid zone of Nigeria, viz, cultivation and fallow. Presents break-even sorghum grain-stylo price ratios for different undersowing times, capital an...

Investigates Nitrogen and Phosphorus transfers in a crop - livestock system in the subhumid zone of Nigeria. Estimates N and P removed from cropland during crop residue grazing and returned to the land through manure, and the contribution crop residues make to cattle diet during the dry season.

Land-use intensification in the East-African highland zone is required for meeting food and feed demands from the rising human and animal populations. A single crop of wheat has been a traditional practice for the 8 Mha of Vertisols in the Ethiopian highlands with both grain and residues finding ...

Defines some of the terms commonly used and misused in forage production and management in relation to farming systems research. Also provides a quick reference of some of the pasture and forage species found in the subhumid zone of Nigeria.

Reports a concerted interinstitutional attempt to generalize the use of the available draught animal power for the construction of more effective soil surface drainage. The hypothesis is that the relatively high productive potential of the Ethiopian highland vertisols, particularly in high-rainfa...
