Contribution of Arbuscular Mycorrhizal Fungi (AM Fungi) and Rhizobium Inoculation on Crop Growth and Chemical Properties of Rhizospheric Soils in High Plants

Arbuscular mycorrhizal fungi and Rhizobium enhance the growth of Samanea saman (trembesi) planted on gold-mine tailings in Pongkor, West Java, Indonesia

“…The application of AMF and Rhizobium in tailings significantly increased colonization by AMF in the roots, the number of nodules in the roots of the seedlings and the presence of AMF spores in the tailings rhizosphere. This finding strengthens the existing knowledge that AMF association with legume plants has a great influence on the development of roots and shoots and the absorption of P which links to the occurrence of nodulation and nitrogen fixation (Pierre et al 2014). It is of great importance to note that microbial colonization was not found in seedlings that were not inoculated, pointing out the absence of microbiome in the tailings.…”

“…NR9 strain. This compatibility is important for management consideration if they are used as biofertilizers (Pierre et al 2014). Results obtained in this investigation suggest the potential application of dual inoculation of S. saman seedlings with AMF and Rhizobium for the revegetation of gold mine tailing fields.…”

“…On the other hand, the establishment of AMF and Rhizobium strains can be considered as indicators of the ability of introduced microbes to survive under the prevailing physico-chemical tailings conditions. Indigenous AMF strains tend to be more adaptive than foreign strains (Pierre et al, 2014). The compatibility of AMF types of Glomus manihotis and Glomus etunicatum inoculum have also been reported to be developed with jabon (Anthocephalus cadamba) seedlings on tailings media in polybags (Setyaningsih et al, 2017), as well as with Typha angustifolia (Setyaningsih et al, 2018a).…”

“…The dominance of plant species and the growth rate of certain plants in a mining area, especially tailings, is strongly influenced by the level of contamination, soil physical and chemical properties, the level of plant adaptation, and other environmental factors in mine tailings (Anawar et al, 2013;Ekyastuti et al, 2016;Setyaningsih 2018b, Lestari et al, 2019, including the adaptability of plants to limit the absorption of heavy metals at the roots (Reichman 2002;Setyaningsih et al, 2012) Dual inoculations with AMF and Rhizobium triggered a better growth of the S. saman seedlings than single inoculation treatment, as previously reported in a number of different plant species (Yaseen et al, 2016;Havugimana et al, 2016). AMF and Rhizobium inoculations can also play a pivotal role in increasing plant growth in areas with high heavy metal content through improved plant nutrition (Pierre et al, 2014). AMF increases nutrient and water uptake, and increases nutrient mineral transporters in plant roots, while rooted nodules fix N2 and also produce antibiotics and phytoalexin.…”

Respuesta agronómica de Phaseolus vulgaris a la biofertilización en campo

“…No obstante, el sinergismo proveniente tras la incorporación de dos microorganismos rizosféricos (Rhizobium-HMA) en el sistema radicular de leguminosas en general (Larimer et al, 2014;Pierre et al, 2014) y de frijol en particular (P. vulgaris cv. CC-25-9) (Liriano et al, 2012) ha constatado su capacidad para mejorar la sanidad y el potencial productivo de las plantas al establecer una simbiosis tripartita con innegable trascendencia ecológica (Bauer et al, 2012;Ossler et al, 2015) y agrícola (Tajini et al, 2012;Brandán de Weht et al, 2013;Martín et al, 2015).…”
