“…Soil K is often reported to have a stimulatory effect on AMF variables (Furlan, and Bernier-Cardou 1989;Ouimet et al 1996) and a minimum soil K is often prerequisite for mycorrhizal colonization in some plant species (Ouimet et al 1996;Gamage et al 2004). The relationships between AMF spore count and soil chemical properties are not steady but it differs according to Glomeromycota community composition (Johnson et al 2013).…”

“…Spore count levels reported in this study are in agreement with the earlier report of AMF status from coconut gardens under basin management with green manure crops (Thomas 1987) but lower than the values reported by (Ambili et al 2012) who recorded 33.83-154.5 spores per 10 g soil from coconut based cropping systems grown with pepper, banana and pineapple as intercrops. Large variations have been reported in AM fungal spore densities associated with same plant species at different sites (Zhao et al 2003;Walker et al 1982;Sylvia 1986) which are attributed to variations in microclimate (Koske 1987) physio-chemical, microbiological properties (Anderson et al 1984;Johnson et al 2013) and the vegetation (Toro et al 1996). The root colonization of AM fungi ranged from 32.33± 8.74 to 55.17±1.61 % which was not significantly different.…”

Degree of arbuscular mycorrhizal (AM) association and its diversity were investigated in the coconut palm (Cocos nucifera L.) cultivated in crop mixed system under rain-fed condition in a highly productive humid tropical zone in Malappuram district of Kerala, India. Forty AM species belonging to ten genera viz. Acaulospora, Claroideoglomus, Dentiscutata, Diversispora, Funneliformis, Gigaspora, Glomus, Redeckera, Scutellospora and Septoglomus were recorded indicating high level of AM richness in coconut rhizosphere. Of these, eighteen AM fungal species are being reported for first time from this palm. Claroideoglomus, Glomus and Gigaspora were the most commonly present genera and Claroideoglomus etunicatum and Glomus aggregatum the common species. The diversity indices (Shannon indices values) of AM fungi associated with coconut palm in a crop mixed system and mono crop varied significantly. The Shannon index, Simpson's index and evenness ranged from 1.40±0.10 to 2.70±0.01, 0.65±0.033 to 0.90±0.004, 0.51±0.01 to 0.82±0.01, respectively. Correlation between soil physio chemical characters and mycorrhizal parameters were worked out. Soil pH had negative correlation with spore count, root colonization, species richness, Shannon H and Simpson indices but had positive correlation with species evenness. Electrical conductivity showed positive correlation with root mycorrhizal colonization which indicated active AMF mediated uptake of nutrients.

“…Even in the Caatinga site, few species were detected that were not detected at least in one of the four cowpea treatments or in the fallow. The species richness observed in our cultivated sites was clearly higher than in areas cultivated with cowpea in two climatic regions of Benin, the sub-humid Guinea savanna and the semiarid Sudan savanna, where 15 AMF species were recovered (Johnson et al 2013). Lower species diversity was recorded in areas of NE Brazil cultivated with cowpea, such as in the pioneer work of Maia and Trufem (1990;24 species), and more recently by Sousa et al (2012), where organic substrates had been applied (21 species).…”

Diversity of arbuscular mycorrhizal fungi in Brazil's Caatinga and experimental agroecosystems

et al. 2017

Cowpea (Vigna unguiculata) is a nutritious legume crop for both its grain and leaves and comprises an important component in both human and animal nutrition. In Brazil, the use of mulch, such as coconut fiber, and organic fertilizers to maximize cowpea production offers an alternative to conventional mineral fertilizer strategies. Farming practices affect the diversity and activity of soil microorganisms, including arbuscular mycorrhizal fungi (AMF), important plant growth promoters for legumes. Our objective was to determine the effect of mulching with coconut fiber and manure on AMF diversity in cowpea. Soil samples were collected from an Experimental Station in Petrolina, NE Brazil: one Caatinga (natural dry‐forest vegetation), one fallow, and one experimental site established in the fallow area and cultivated with cowpea receiving cattle manure and four doses (0, 12, 24, 48 t/ha) of coconut fiber. AMF species richness, abundance, and diversity were evaluated. Sixty‐four AMF species were recorded, with predominance of Glomeraceae and Acaulosporaceae. Highest species richness (47) was recovered from the Caatinga but AMF diversity was also high in the cultivated sites, demonstrating the importance of mycotrophic plants, such as cowpea, in crop production systems for the maintenance of AMF species richness. Although several species, such as Claroideoglomus etunicatum, Acaulospora scrobiculata, Glomus trufemii, and Paraglomus pernambucanum, revealed pronounced sporulation patterns, even high doses of coconut fiber did not affect AMF richness and diversity, compared to fallow. Consequently, cultivation of mycotrophic plants and use of organic manures are able to maintain high AMF species richness in tropical agroecosystems.

“…In addition, many reports have investigated the functional ecology of temperate forage plants on grassland (Frey and Schüepp, 1992;van der Heijden et al, 1998;Hartnett and Wilson, 2002;Kojima et al, 2007;van der Heijden et al, 2008;Bauer et al, 2012;Eisenhauer et al, 2012;Sabais et al, 2012;Vinichuk et al, 2013;Schneider et al, 2015) but few have researched tropical and subtropical forage legumes (Dodd et al, 1990a;1990b;Soedarjo and Habte, 1995;Boddington and Dodd, 2000;Alguacil et al, 2010;Johnson et al, 2013).…”

This study examined the growth and Arbuscular Mycorrhizal (AM) colonization of two tropical forage legumes, namely, American jointvetch (Aj) and Greenleaf desmodium (Gd), at two phosphate application rates (0 or 10 g P m −2 yr −1 ; -P or +P), with or without AM (+AM or -AM) in a pot experiment. AM inoculation and P application promoted the growth of both species. AM inoculation in the early growth stages promoted colonization in both species, but P application did not. Nitrogen and phosphorus concentrations were affected by neither AM inoculation nor P application. Nitrogen uptake in both Aj and Gd, however, was affected by both AM inoculation and P application. Phosphorus uptake was affected by AM inoculation in Aj and by P application in Gd. The results suggest that both P application and AM promoted legume growth and AM colonization was not suppressed by P application. Nevertheless, plant responses to the treatments varied with species and growth stage.
