Feed resources and nutrition constitute the principal technical constraints to ruminant production in Asia. Four main categories of feed resources are potentially available for use in smallholder crop-animal systems. These are pastures (native and improved grasses, herbaceous legumes and multi-pu...

The predominant farming system in La Colorada (Magdalena, Colombia), where cassava is a subsistence crop, is briefly reviewed. The intensive land use has caused soil leaching and infestation with root pathogens such as Diplodia manihotis and Fusarium oxysporum and cassava production has decreased...

This article addresses concerns of technology dissemination for small farmers, specifically focusing on the diffusion of new varieties of a self-pollinating crop. Based on bean seed systems research in Uganda, Rwanda, Burundi, and the Democratic Republic of Congo, it shows four commonly-held basi...
