Effects of Arbuscular Mycorrhizal Inoculation and Phosphorus Application on Yield and Nutrient Uptake of Yam

Diversity of arbuscular mycorrhizal fungi in soils of yam (Dioscoreaspp.) cropping systems in four agroecologies of Nigeria

“…Because soybean has a growth cycle of three months, the shoots were removed and the pots (with the substrate left undisturbed) were replanted with the same plant species. Trap pots were watered with distilled water and fertilized once every two weeks with 50 mL of Hoagland nutrient solution (Dare et al 2010). At five months after planting, plant shoots were removed from each pot and the substrate inside each pot was thoroughly mixed.…”

“…This association evidently improves the uptake of mineral nutrients such as P, N, Zn and Cu in plants (Allen et al 2003;Smith and Read 2008;Dare et al 2010), suppresses plant diseases (Borowicz 2001;Abdel-Fattah and Shabanam 2002), improves plant tolerance to drought and water stress (Fagbola et al 2001; Auge´2004) and stabilizes soil structure (Rillig and Mummey 2006). The occurrence of AMF in soils varies in population and diversity across ecologies and is affected by various factors including soil and environmental conditions, host plant and agricultural practices such as crop rotation, fertilizer application and tillage (Miller and Jackson 1998;Jansa et al 2002;Oehl et al 2003;Mathimaran et al 2007).…”

Evaluation of White yam (Dioscorea rotundata) genotypes for arbuscular mycorrhizal colonization, leaf nutrient concentrations and tuber yield under NPK fertilizer application

“…It is evident that plant nutrition in depleted soils can be enhanced by the colonization of plant root by arbuscular mycorrhizal fungi (AMF) (Smith and Read, 2008). Yam has been reported to be highly colonized by AMF with benefit of increased P and N uptake (Zaag et al, 1980, Dare et al, 2010. Studies on the selection of yam genotypes for efficient arbuscular micorrhizal (AM) colonization have also been conducted (Dare et al, 2008).…”

Microbial Inoculants for Soil Quality and Plant Health

“…The mechanism of increased P uptake by Arbuscular mycorrhizal fungi has been attributed to the fungal extra radical hyphae growing beyond the phosphate depletion zone that develops around the root (Smith and Read 2008). Positive effects of arbuscular mycorrhizal fungi inoculation on the growth and P nutrition of crops have been reported (Cozzolino et al 2013;Dare et al 2010). Many mycorrhizal inoculants have been produced on a commercial scale, mostly in the US and Europe.…”

“…Many mycorrhizal inoculants have been produced on a commercial scale, mostly in the US and Europe. Rhizophagus (formerly Glomus) intraradices and Funneliformis (formerly Glomus) mosseae (Kruger et al 2012) are some of the common mycorrhizal inoculants which have been shown to increase P uptake in diverse crop plants (Dare et al 2010;Cozzolino et al 2013). Some other fungi such as Aspergillus and Penicillium species are able to solubilise inorganic phosphate and mineralise organic phosphate by secreting organic acids and producing phosphatase enzymes (Wang et al 2015).…”
