Effects of Rhizophagus intraradices on Plant Growth and the Composition of Microbial Communities in the Roots of Continuous Cropping Soybean at Maturity

Soybean is the major food and oil crop in world. However, soybean continuous cropping can significantly reduce yield. In this study, effects of Rhizophagus intraradices on growth composition microbial communities roots under different regimes were investigated at maturity. The results showed that mycorrhizal colonization rate was affected by R. cropping. highest inoculated plants 1 year Inoculation increased plant growth. greatest biomass parameters obtained from with 0 years Bacterial diversity decreased cropping, while opposite result occurred for fungal diversity. Moreover, inoculation could increase decrease bacteria fungi roots, respectively. It also indicated had significant roots. Proteobacteria Ascomycota most dominant bacterial phylum all samples, would contribute to developing a biocontrol strategy alleviate obstacles.
