“…Regarding the link between soils and mycorrhizal parameters, our observations confirm the results of Ngakou et al (2020) who showed that a substrate composed of 2/3 soil and compost added to 30g mycorrhizae is ideal for garlic production by mycorrhizal fertilisation. For the distribution of mycorrhizal spores in the study site, Tobolbaï et al (2018) obtained similar results, reporting that Glomus constrictum is the most abundant specimen in the rhizosphere of maize grown in North Cameroon.…”

“…These interactions can be very beneficial for plants, as is the case of the symbiotic plant-fungus endomycorrhizal association (Alabouvette andCordier, 2018, Diedhiou et al, 2022). Indeed, the fungal strains involved in this symbiosis are capable of improving the plant partner's hydro-mineral nutrition (Lambers et al, 2008), drought resistance (Leyval, 2005), yield (Ngakou et al, 2007;Ngakou et al, 2020), resistance to pathogens and pests (Elsen, 2003), and nutrition in polluted environments (Chen et al, 2007, Koffi et al, 2021. In addition, these micro-organisms stabilise soil aggregates by releasing a protein substance called glomalin (Rillig and Steinberg, 2002).…”

“…In addition, these micro-organisms stabilise soil aggregates by releasing a protein substance called glomalin (Rillig and Steinberg, 2002). Therefore, the technology of this symbiosis, which is now valued in crop production, deserves to be promoted to reduce the use of inorganic fertilisers and pesticides, in order to promote ecological and sustainable agricultural production, (Ngonkeu et al, 2013;Nadjilom et al, 2019;Koffi et al, 2019). On the other hand, leguminous crops such as cowpea, and groundnut contribute enormously to soil fertilisation through symbiotic fixation of atmospheric nitrogen (Bado, 2002).…”

The Sudano-Sahelian part of Cameroon is known for its severe climatic conditions and low soil fertility. Local farmers use chemical fertilisers to increase crop production, usually without moderation. As a result, there is environmental pollution such as soil acidification, production of greenhouse gases, and increased eutrophication. To face this situation, scientific research recommends ecological solutions such as bio-fertilisers to enhance soil fertility. In this context, the mycorrhiza symbiosis technology deserves special attention. Indeed, it is a beneficial association between soil fungi (Glomeromycota) and the roots of more than 85% of plants; the evaluation of the agronomic potential of these microorganisms has shown spectacular results under field conditions. This study analyses the status of indigenous arbuscular mycorrhizal fungi in the cowpea rhizosphere in the agro-ecological zone 1 of Cameroon. For this purpose, soil samples were collected from the Far North and North regions of Cameroon. Composite soil samples were obtained by mixing soils collected from three divisions per region. Cowpea was grown in pots on these composite soil samples for 3 months. At maturity, spores of mycorrhizal fungi were isolated and parameters including mycorrhization frequency and intensity, the specific spore’s density and richness were evaluated. The spores were characterised according to morpho-anatomical criteria. The results established that between localities, mycorrhization frequency varied between 7-19%; mycorrhization intensity, 7-17.28%; specific density, 0.66-44% and specific richness, 2-4%. Eight specimens of arbuscular mycorrhizal fungi in six genera were characterised: Acaulospora (A. kentinensis, A. myriocarpa); Ambispora sp; Diversispora epigae, Funneliformis mossea, Glomus (G. constrictum, G. manihotis, and G. maculosum) and Rhizophagus intraradices. G. constritum was predominant in all the studied sites, followed by R. intraradices, while Acaulospora myriocarpa was the rarest. These results pave the way for the selection of indigenous arbuscular mycorrhiza fungi for ecological cowpea production in this area.

“…In Togo, inoculation of soybean plants with mycorrhizae resulted in an improvement in plant height from 14 to 32 cm [54]. Also, the work of Ngakou et al [55] on garlic plants inoculated with mycorrhizae under greenhouse conditions observed an improvement in plant growth from 4.85 cm to 6.28 cm. Ogou et al [54] obtained in Togo an average mycorrhizae-induced pod gain on soybean of +126.83% compared to the control.…”

Excessive application of chemical fertilizers and other agrochemicals can cause significant imbalances in soils and agricultural ecosystems. To minimize these impacts, biofertilizers and organic fertilizers are needed to maintain a sustainable production system. The use of subterranean microorganisms in agriculture to stimulate plant growth and improve yields has recently received increasing interest. In this context, mycorrhizae represent a viable solution to mitigate these adverse effects. Mycorrhizal fungi are able to form a symbiotic relationship with the roots of plants in the environment. Mycorrhizal fungus helps the plant to absorb nutrients and water. In addition, mycorrhizal fungi play a crucial role in storing carbon (C) in the soil. Most previous studies have just considered the effects of AMF species on a specific crop in one particular area but have not assessed the balance of AMF in production systems in tropical agriculture. This consideration should allow for the optimization of cropping practices through a review of the work on the use of AMF in tropical agriculture production systems. In this paper, we will discuss, through different examples of experiments carried out in the tropics, the performance of different strategies for managing the potential of AMF to maintain a sustainable production system.
