Abstract
Vigna subterranea, known as voandzou or Bambara groundnut as an African indigenous crop which is often neglected or under-used in African subsistence agriculture. Preliminary research and country perceptions have shown its agronomic and nutritional properties, in particular under atypical climates of arid and tropical areas, and in saline soils. There is a high potential to increase the production by optimizing symbiotic nitrogen fixation (SNF) through effective inoculation even in nitrate-rich environments. In this study, Vigna subterranea inoculated with the reference strain of Bradyrhizobium sp. Vigna CB756 was studied in order to assess the symbiotic fixation potential of different cultivars and landraces of Madagascar, Niger and Mali under low-P and sufficient-P conditions. Six voandzou cultivars inoculated with Bradyrhizobium sp. Vigna CB756, were grown under hydroaeroponic culture for 6 weeks supplied with four phosphorus levels of 15, 30, 75 and 250 {mu}mol plant{sup -1} week{sup -1} in order to establish the response curve of voandzou to P supply, and to induce P deficient and sufficient levels. In another experiment five tolerant cultivars with high SNF and five sensitive cultivars with low SNF were chosen after a preliminary screening of 54 voandzou genotypes, including 50 landraces from Madagascar, Niger and Mali supplied with

Genotypic variation in SFN for the high phosphorus use efficiency (PUE) was observed among the 54 cultivars and landraces. Variability was especially related to the nodule and shoot biomass, nodule permeability, nodule respiration and gene phytase expression.
