Abstracts |
Improvement of soil fertility and promotion of sustainable agriculture in Adamawa region is feasible if under-utilized crops such as bambara groundnut (Vigna subterranea) could be inoculated by Rhizobium and mycorrhiza strains in the field. An experiment was conducted in a completely randomized block design with five treatments; each of which was repeated thrice: control, Rhizobium, mycorrhiza, Rhizobium+mycorrhiza and chemical fertilizer. V. subterranea seeds used had a very high emerging capacity of between 92-100%. The soil organic matter was reduced by 20 to 30% after harvest, indicating their utilization for plant growth. Compared to un-inoculated plants, Rhizobium and mycorrhiza significantly (p≤0.0007) increased nodulation and plant biomass at 30 and 60 DAP. The number of root nodules was reduced as from 50 days after planting, but increased in their dry weight, as an indication of their effectiveness to nodulation. The seed yield at harvest of Rhizobium+mycorrhiza treatment was boosted to three folds than that of control. Based on these results, it is suggested to prescribe the sustainable improvement of bambara groundnut production through Rhizobium+mycorrhiza inoculation. |
