Role of root-nodule bacteria in nitrogen fixation and mineral density in symbiotic legumes

M. Tech. Agriculture. Department of Crop SciencesThe aim of this study was to screen cowpea and Bambara groundnut root-nodule bacteria for symbiotic efficacy and their ability to induce nutrient uptake in sterile Leonard jars. The following sub-aims were indicated: To assess 16 root-nodule bacteria isolated from cowpea plants for their symbiotic efficacy on a) cowpea, b) siratro and Kersting's bean, as well as c) four shrub/tree legumes ; To assess the effect of their symbiotic efficiency on mineral nutrient uptake of the host plants ; To evaluate slow- and fast-growing root-nodule bacteria isolated from Bambara groundnut plants for their symbiotic efficacy on their homologous host and ; To assess the effect of their N2-fixing efficacy on mineral nutrient uptake
