Abstract

Bambara groundnut (BG) ( Vigna subterranean L. verdc ) is a highly nutritious underutilized leguminous crop of African origin with high economic importance. Its production rate (300,000 metric tonnes/year) does not meet the current demand (800,000 metric tonnes/year). Despite it’s useful properties, it has remained neglected, with poor market and low yields because research about improving BG has been neglected. rhizobia have proved to be useful in promoting the growth of legumes, yet, there is unavailable information about the role of indigenous BG-symbiont rhizobia inoculant (which are better affordable alternatives to chemical fertilizers) for increasing BG yield and this needs to be explored, hence this study. This experiment studied the role six rhizobial strains in improving the biomass and plant vigour of two selected varieties of BG (TVSU 1248, TVSU 631). These strains were applied as inoculant (at concentrations of > 0.85 × 10 10 cfu/ml) on field compared alongside commercial USDA110 strains and Urea (rates of 60 kg/ha and 20 kg/ha) treated plants and analysed for biomass of shoot, root, shaft and seed, and moisture etc. Rhizobia significantly influenced the shoot biomass (≥ 19.26 g), (79.81 ± 1.81 g and 63.15 ± 3.21 g), root biomass (≥ 0.63 g), pod biomass (≥ 155.3 g), seed biomass (≥ 103.96 g), shaff biomass (≥ 52.29 g) and moisture content of the plants, with differences in varietal response. Indigenous BG-symbiotic strains are able to significantly influence plant vigour and biomass, promoting the growth and health of BG. Rhizobia, proved to be useful for enhancing the plant biomass, vigour and growth and should be recommended for improving the production of BG for higher yield and productivity.
