The linkages between cassava production and the key agronomic and climatic factors were investigated with a view to estimating the supply response for cassava in Nigeria. Time series data from FAO and the International Institute of Tropical Agriculture, 1961–2008, were used for the study. Data we...

The poor quality of the natural vegetation in the dry season affects both animal productivity and the lives of the pastoral community in the Adamawa Plateau of Cameroon but may be improved by introduction of the forage legume Stylosanthes guianensis. When used in a fodder bank system, Stylosanthe...

A greenhouse experiment was conducted to determine the critical deficiency levels of potassium (K) in the subhumid zone soils for predicting response of a mixture of Andropogon gayanus and Stylosanthes hamata cVerano to K application. Twenty coarse textured soils, having loamy sand to sandy loam ...

Critical potassium deficiency levels for a grass legume pasture grown on soils of the subhumid zone of Nigeria
The fast depletion of available potassium (K) in soils of the subhumid zone (SHZ) of Nigeria has become a problem for the formulation of fertilizer recommendations, especially in the grass/legume mixtures of the fodder bank system. Five different K fertilizer recommendation models viz. Control, C...

Over a grazing period of about 14 weeks, comparisons were made between pasture improved with Stylosanthes hamata and that based on natural grassland. The grazing densities ranged from 2.11 to 4.23 TLU/ha (Tropical Livestock Unit = 250 kg liveweight). Both pastures were grazed in the previous wet ...

Twenty surface soils (0 to 15 cm), selected to represent a wide range of available potassium (K) status and three different land-use systems (fodder bank, continously fertilized cropped land and fallow land) across the subhumid zone of Nigeria, were used for the investigation. Laboratory and gree...

The household head characteristics of smallholder cassava farmers supplying raw materials to the major commercial starch processors in Nigeria were examined alongside their market participation categories. A multi-stage random sampling technique was used to select 96 farmers working in clusters i...

Thirty-two herds of West African Dwarf goats raised under village conditions and which grazed stylosanthes (Stylosanthes hamata cVerano) or natural pasture in the wet season were monitored for 30 months to determine herd productivity. Average litter size was 1.67 (+ or -) 0.082, kidding interval ...
