L‘intégration des légumineuses fixatrices d‘azote dans les systèmes techniques de production a donné lieu à de nombreux travaux de recherche destinés à améliorer ou restaurer la fertilité des terres, mais très peu de ces systèmes techniques sont vraiment appropriés par les paysans en Afrique de l...

Amélioration de la gestion des sols par l'introduction de légumineuses dans les systèmes céréaliers des savanes africaines
The parasitic angiosperms, Striga hermonthica and S. gesnerioides, obligate root parasites endemic in sub-Saharan Africa, constitute severe constraints to cereal and legume production in West and Central Africa. Over the years, a range of effective component technologies has been identified for S...

Characterisation of scaling out and scaling up networks of CPWF projects
Two sets of on-farm trials, each covering two years, were conducted in the northern Guinea savannah of Nigeria over the period 1999–2001, the objective being to compare integrated Striga hermonthica control measures (soybean or cowpea trap crops followed by maize resistant to Striga) with farmers...

An assessment of integrated Striga hermonthica control and early adoption by farmers in Northern Nigeria
This paper evaluates the utility of the `learning selection' model of the early adoption process, based on a constructivist conceptual framework, to explain farmers' adoption and rejection of two soil-improving technologies alley farming and the use of Mucuna cover crops. The analysis showed th...
