“…The impacts of soil salinity on spore germination of AMF growths, and consequently hyphal generation, is a standout among the most critical adverse effects of salinity on mycorrhizal colonization (Juniper & Abbott, 2006). Therefore, the presence of AMF in salt land may depend on the type of host plant and may not on the environmental stresses (Nurbaity, 2014).…”

Recently more attention has been observed toward the role of arbuscular mycorrhizal fungi (AMF) in plant growth. Qatar belongs to the Arabian Gulf region with hot and dry climatic conditions. The study aims to investigate the species composition and abundance of AMF in Qatar, rhizosphere soil samples, and roots of plants from 12 families and 8 different locations. The AMF were identified based on the sequencing of the polymerase chain reaction (PCR) product of the amplified conserved ITS region. The reported AMF infection rate was found to vary with location and plant species. Tamarix aphylla recorded the highest AMF infection rate (100%), followed by Blepharis ciliaris (98%) and Sporobolus ioclados (92%). AMF spore counts ranged from 29.3 spores in Blepharis ciliaris to 643 spores/100 g soil in Fagonia indica . No correlation was detected between colonization rate and spore counts. While all AMF identified at species levels were reported in other regions, new species are still expected since some were identified only at higher taxonomic levels. Claroideoglomus drummondii and Rhizophagus irregularis were the most widespread while Claroideoglomus claroideum and Diversispora aurantia were the least present. Our results fill the gap of knowledge of AMF in the region and opens new research toward its future applications for sustainable agriculture.

“…Among these practices, biofertilization with arbuscular mycorrhizal fungi (AMF) can present a promising solution. In fact, mycorrhizal inoculation had taken the intention of scientists (Adesemoye and Kloepper, 2009) for its role in increasing plant growth and mineral uptake, especially phosphorus, thanks to the extra-radical fungal hyphae (Nurbaity, 2014;Smith and Read, 2008), enhancing soil quality (Junior et al 2018) and improving plant tolerance to Fusarium, Verticillium and Bacterial wilts (Boutaj et al 2022). Few studies (Hijri, 2006;Douds et al 2007) have shown the efficiency of arbuscular mycorrhizal fungi (AMF) inoculation for potato crop.…”

To improve sustainable agriculture it becomes crucial to minimize the use of chemical inputs and involve new practices that are more productive and healthier for humans and environment. Biofertilization with arbuscular mycorrhizal fungi (AMF), known for increasing the productivity of many crops including potatoes, could be considered as one of these sustainable practices. The purpose of this study was to determine whether mycorrhizal inoculation can minimize chemical fertilization for potato (Solanum tuberosum L.), one of the most demanding species in mineral elements. Thus, by studying the effect of chemical fertilization and mycorrhizal inoculant on potato yield and soil quality. Two doses of chemical fertilizer (NP) corresponding to 50 % and 100 % of the recommended dose has been applied in the presence or not of the mycorrhizal inoculant. The results have shown that adding arbuscular mycorrhizal fungi in combination with 50 % of the chemical fertilizer dose gives the best effects. A significant increase in yield, root colonization, and P soil content has been observed (P < 0.001). Thus mycorrhizal inoculation could reduce the application of synthetic fertilizers and thus improve yield while preserving the environment.

Mycorrhiza has been known could increase plants’ nutrient uptake through promoting root zone which resulted in higher yield production. A glasshouse experiment was conducted to optimize the technology for arbuscular mycorrhiza biofertilizer production through hydroponic system with automatic watering system and nutrient solution modification. Sorghum bicolor was used as host plants, grown for six weeks on medium contained mixture of zeolite and rice husk charcoal with the addition of arbuscular mycorrhizal fungi inoculum. Different hydroponic techniques (Deep Flow and Ebb Flow) and phosphorus content in nutrient solutions (0, 20, 40, 80 ppm) were tested. Results showed that different types of hydroponic system and rates of P in nutrient solution gave significant differences in increasing mycorrhizal colonization in roots, number of mycorrhizal spores, P uptake and biomass of plants. The best hydroponic technique was Ebb Flow with P content 40 ppm which was 50% lower than the standard nutrient solution for hydroponic. These findings suggest that the production of mycorrhiza biofertilizer through optimization of nutrient solution and growing medium in hydroponic system was potential for future practice. This technology could be used for mass production of “clean” and good quality of mycorrhizal biofertilizer.
