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...

The dry matter (DM) yield and degradability of 6-week-old harvests of tropical forages were measured over a season. The forages were nitrogen-fertilized Guinea grass (Panicum maximum, NFG), unfertilized Guinea grass (UFG), Verano stylo (Stylosanthes hamata,VS), a Guinea grassVerano stylo mixture ...

This study was conducted to establish parameteres on the optimum spacing and level of nitrogen required for the establishment of most cultivated grass pastures including Brachiaria decumbens. It was found that 20x20 cm spacing of rooted sprigs of signal grass and either 100 or 200 kg N ha were si...

Two crop rotation cycles were evaluated to determine the effect of cropping systems and N fertilization on the yield and efficiency of N in maize. Maize was grown on plots which had previously supported monocrops of two genotypes each of soybean (TGx 1448-2E and SAMSOY-2) and cowpea (IT 96D-724 a...

Inadequate nitrogen nutrition is a major constraint to the performance of common bean (Phaseolus vulgaris L.) in sub-Saharan Africa. Twenty six lines selected for good performance under N-limiting conditions were further evaluated at two locations in Uganda to determine the mechanisms allowing go...

Maize (Zea mays L.) and bean (Phaseolus vulgaris L.) are commonly grown in association in eastern and southern Africa. Results from 64-fertilizer response trials conducted in Kenya were used to study the relationship between maize monoculture response to fertilizer nitrogen and phosphorus and the...

Nitrogen fertilizer is the major input in rice production and the optimum rate and application timing management assure profitability and sustainability of the production system. This study aims to investigate hybrid rice response to different nitrogen fertilizer levels and the timing of applicat...
