Effect of Single Superphosphate and Arbuscular Mycorrhizal Fungi on Growth and Bambara groundnut (Vigna subterranea (L.) Verdc.) Yield
This work is the result from the testing of biofertilizer obtained from a previous research work on growth and yield of Bambara groundnut (Vigna subterranea (L.) Verdc.). It showed that this biofertilizer increased growth and yield same as with chemical fertilizer. Hence, this product (biofertilizer) can replace or reduce the use of chemical fertilizer which not only costly for farmers but it is also not environmentally friendly.
