Field studies were conducted between 1987-1989 at sites on Vertisols at different altitudes in Ethiopia to assess the effects of mixtures of clover undersowings on grain, straw yield and the total biomass production of several wheat varieties. Wheat varieties grown at the medium altitude location...

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...

Presents and discusses ILCA's research approach on the development of sustainable feeding systems for increasing small ruminant production on smallholder farms. Examines in detail the three levels of interrelated research activities, viz, strategic research, commodity research and on-farm develop...

The subhumid zone has a great potential in terms of carrying capacity to increase ruminant livestock production in Nigeria and tropical Africa in general. This paper reviews livestock distribution, land use constraints, feed resources and their effects on livestock productivity in the zone. Natur...

Stover selling, transporting, trading and its use in dairy production support the livelihood of many people from producers (farmers) to the end users in Hyderabad, India. This study explored the economic value of sorghum stover in fodder trading and the relationship between stover price and quality.

Conservation agriculture (CA), comprising minimum soil disturbance, retention of crop residues and crop diversification, is widely promoted for reducing soil degradation and improving agricultural sustainability. It is also claimed to mitigate climate change through soil carbon sequestration: we ...

In communal areas of NE Zimbabwe, feed resources are collectively managed, with herds grazing on grasslands during the rainy season and mainly on crop residues during the dry season, which creates interactions between farmers and competition for organic resources. Addition of crop residues or ani...

Striga hermonthica is a serious parasite of cereals in most of the semi-arid savanna zone of West Africa, causing substantial yield loss. It has been observed that some soybean cultivars are capable of stimulating germination of S. hermonthica seed, which would reduce the seed bank in the soil. T...
