    Important agronomic characteristics of common root and tuber crop production systems in the tropics are indicated for crops including cassava, yam, sweet potato, and edible aroids. Brief comments are also included on aspects that help correctly interpret the information obtained during the characterization process. The general context of agricultural production is analyzed, and within this context, the particular case of root crops, where the process of transformation into derived products, at both farm and regional levels, may condition the agronomic practices used.

    Using the farm as unit of analysis, diagnosis processes aimed at improving production systems are reviewed. Within a country, diagnosis should be conducted at different hierarchical levels: local (interaction between the production system and the input distribution sector, the marketing sector, possible forms of processing, and consumption characteristics); regional (appropriate selection of target site); and national (development trends and governmental policies at the macroeconomic and sectorial levels).

    This study identifies the causes of the observed differences in flock productivity in a central Malian village, in a rainfed millet agropastoral subsystem. Small ruminant productivity, management factors and socio-economic characteristics are analysed. The causes leading to the observed differences in small ruminant productivity are related to the owner's socioeconomic characteristics, to his management strategies or to preferences for one or the other small ruminant species.

    Reviews the extent and use of crop residues as livestock feeds in Ethiopia with special emphasis to wheat with respect to varietal difference and agronomic practices to enhance the utilisation of the straw. Lists area and yield of major crops in Ethiopia. Presents data on yield & chemical composition of various crop residues, weight gains of steers fed crop residue, and effect of N fertilization on grain yield and quality & quantity of wheat straw. Also summarises results of an undersowing trials of forage crops to wheat.
