Effects of Bambara groundnut [Vigna subterranea (L.) Verdc.] interaction with Rhizobium spp. for viable yield crop advancement

Viable yield crop remains a preference towards avoiding food insecurity in any country, yet, the fertility of most of the soils in Africa is low, which is the main reason why sustainability does not receive enough support by any means. Various agricultural systems have been carried out to solve the challenges, but many restrictions have been recorded, thereby resulting to a constant little or no crop of local basic food crops in several countries in Africa. Scientists and farmers have become interested in the symbiotic relationships between “Legumes” and “Rhizobia” because of their effectiveness in nitrogen fixation as a true alternative. The blend of Nitrogen Fixing Legumes (NFL) with novel essential reverence yields among small-holder farming structures is possible to improve the fertility of soil. The seed of legumes, in particular, Bambara groundnut (i.e. African Bambara groundnut) creates nitrogen fixing symbiotic interaction together with the bacteria of root nodule collectively termed “Rhizobia” in such a manner that sufficient nitrogen are released for legume and diverse yields during inter-crop or crop rotation. Through this method, it is expected to be considered as a food crop that is necessary for food security thereby giving serious considerations on its usefulness and healthy benefits. As a discourse of significance, it is expected to be referred as a cash crop, as well as an essential preference for promoting the soil's nitrogen fertility.
