Velvet bean (Mucuna pruriens (L.) DC. cv.-group utilis) is widely promoted in tropical and sub-tropical regions as a green manure cover crop that can reduce weed growth and soil erosion and enhance soil fertility. To provide these benefits, the crop must attain rapid ground cover and develop subs...

Adaptation of the CROPGRO growth model to velvet bean (Mucuna pruriens). II. Cultivar evaluation and model testing
A programme of forage legumes evaluation was developed at ILCA subhumid research site in Nigeria from 1985 onwards. Evaluation included monitoring herbage and seed yields, incidence of diseases/pests, regeneration ability and persistence for three growing seasons. This was followed by an in six b...

Evaluating selected forage legumes for livestock and crop production in the subhumid zone of Nigeria
The evaluation of Stylosanthes species has featured prominently in ILCA's forage evaluation programme in the subhumid zone of Nigeria. The evaluation of over 200 accessions within the genus using a series of evaluation stages ranging from small plot observation trials through to full-scale grazin...

The potential impact and return to investment from introducing improved dualpurpose cowpea for food and fodder in northern Nigeria was investigated using a combination of farmers' workshops and village and household level surveys. Out of the 462 households surveyed, 41 % were adopters, 9% had bee...

Stylosanthes species have featured prominantly in the forage evaluation program at Kaduna in the subhumid zone of Nigeria. This paper describes the evaluation of an Australian collection of 163 S. hamata accessions using small plot observations, agronomic trials, and assessment of the effects of ...

Evaluation of Stylosanthes hamata (L.) Taub. accessions for livestock and crop enterprises in subhumid Nigeria
Trials were conducted at 7 sites in northern Nigeria to identify forage legumes as alternatives to Stylosanthes hamata cVerano. Initial screening of 46 accessions at each site led to the identification of the best 8 for each site. These were then tested for 4 years, the first 2 with careful manag...

Improving pasture resources in West Africa: Evaluation of forage legumes to meet the social and ecological constraints
Chamaecrista rotundifolia cWynn has been identified as a promising forage legume for use in subhumid Nigeria. To establish if other accessions of this species have potential in the region, 21 accessions were evaluated for flowering, seed production, dry matter production, disease and pest inciden...
