Simultaneous intercropping is a crop-management strategy that is applied by the majority of small-scale farmers in the derived savanna of West Africa. Developing improved systems that are close to farmers' practices is likely to lead toadoption. This paper report economic results from a 2year on-...

This paper reports on a study of the influence ofdrought and inoculation with mycorrhiza on dry-matter production, nutrient uptake and water relations of Acacia auriculiformis, Albizia lebheck. Gliricidia sepium and Leucaena leucocephala in a sterile soil. Inoculation with L. leucocephala roots c...

Considerable progress has been made in breeding improved cowpea varieties in the last five years. The major breeding objectives were to develop high yielding cowpea varieties for sole cropping as well as intercropping with acceptable seed types and resistance to major diseases, insect pests, nema...

Alternative technologies that maximize the use oflocal resources and improve the sustainability of crop production in Rwanda are needed. Promising species for the semi-arid highlands, where the research reported in this paper was conducted, include mucuna (Mucunaprwiens) for fallow periods of 1 4...

Crops' incompatibility makes conventional breeding approaches untenable in transferring available insect resistance From wild Vigna sp. into cowpea. The alternative recourse is to isolate and transfer alien resistance genes using genetic transformation. This has the added advantage of using usefu...

Over the last three decades, sporadic efforts have been made to develop regeneration and transformation systems in cowpea ( Vigna unguiculata L. Walp). This paper reviews the progress made to date, including highlights of culture media and explants used for regeneration and chimeric gene construc...

Host-determined traits influence nodule initiation, development, and function. and can be of major importance to the proper functioning of the legume Rhizobium symbiosis under field conditions. Thls paper reviews such traits and considers their implications for practically oriented breeding progr...

This paper is comprised of five parts. The first part discusses the role of legumes in sustainable soil management and crop-livestock production. In this part, strategic use of legumes, selection of forage legumes to sub-optimal soil conditions, use of appropriate rhizobium, response of legumes t...
