Influence of Arbuscular Mycorrhizal Fungi on the Performance of Glycine max (L.) Merr. Grown on Acidified Soil

Mycorrhiza is an association between the roots of vascular plants and fungus, with a protective role for plants rooted in soils with high metal concentrations, such as acidic and contaminated soils. This study evaluated different pH levels with the inoculation of Mycorrhiza (Glomus deserticola) to ascertain the influence of mycorrhiza on performance of Glycine max cultivated on acidified soil. The study consisted of 5 various levels of pH as treatments [L1 (6.00), L2 (5.50), L3 (4.56), L4 (4.00) and the control L0 (4.96)] with 6 replicates laid in a Completely Randomised Design (CRD). TGX 1465- ID Glycine max seeds were cultivated in a pot containing 10 kg sterilized soil. Plant growth parameters were taken bi-weekly after planting while soil physico-chemical parameters were analysed before and after planting using standard procedures. The results obtained for plant growth parameters showed that there was no significant difference among all the treatments as compared with the control. The Phosphorous content (P), Cation Exchange Capacity (CEC) and Organic Carbon (OC) of AMF inoculated soil samples were significantly higher than that of soil before planting (BP) as follows: P – L1(5.40 mg/kg) ˃ BP (1.36 mg/kg), CEC – L1(6.15 Cmol/kg) ˃ BP (4.66 Cmol/kg) and OC – L1 (0.51 %) ˃ BP (0.20 %). The AMF inoculation buffered the soil pH as follows: L1 (reduced from 6.00 to 5.20), L2 (reduced from 5.50 to 5.15), L3 (increased from 4.56 to 5.10) while L4 (increased from 4.00 to 4.87) The results obtained from this study indicated that inoculation of AMF buffered soil pH, enhanced soil structure; increased soil nutrients, growth and yield of Glycine max. Furthermore, soil acidification should be avoided because based on the experiment, pH range for optimal performance of Glycine max is 5.5 – 6.5. Read more
