Efficacy of mycorrhizal inoculations on seed germination and plant growth of Bambara groundnut, Vigna subterranea (TVsu 283)

This Research work was conducted to study the effects of mycorhizal fungal inoculation on seed germination and plant growth of Bambara groundnut (Vigna subterranea). The impacts of Glomus mosseae, Aspergillus niger, Aspergillus fumigatus and Malbranchea gypsea on some plant growth parameters were studied both in their crude and pure forms. Compared to un-inoculated plants, the fungal strains significantly increased plant growth parameters. The highest rate of germination at the 42nd day was observed in the crude fungal inoculation treatments and specifically in A. fumigatus crude inoculation as it increased the number of leaves, leaf length, leaf surface area, stem girth, and number of shoots by 54.2, 23.8, 49.1, 20.0 and 40.0%, respectively.
