“…The AMF spore abundance recorded in this study were comparable with the findings from different tropical areas [32,39,41,44,85]. Spore densities in this study were higher than the findings conducted by [36,89,90]and lower than those obtained by [91] in Ivory Coast.…”

“…In Ethiopia, there were studies that have been conducted on AFP/land use type and AMF related in different parts of the region. The effects of dry afromontane forest, fragmented church natural forest and different land use types on AMF root colonization and diversity in northern Ethiopia were reported [39][40][41][42][43]. From central parts of Ethiopia, it was found that land use types drastically affected AMF colonization and diversity in dryland AFS [44].…”

The conversion of an agroforestry based agricultural system to monocropping farming system influences the distribution and composition of arbuscular mycorrhizal fungi (AMF). The objective of this paper was to analyze AMF species diversity, spore density and root colonization across different agroforestry practices (AFP) in southern Ethiopia. Soil and root samples were collected from homegarden, cropland, woodlot, and trees on soil and water conservation based AFP. AMF spores were extracted from the soil and species diversity evaluated using morphological analysis and root colonization from root samples. The spore density, root colonization and the composition of AMF were significantly different among the AFP (P < 0.05). In this study, a total of 43 AMF morphotypes belonging to 11 genera were identified, dominated by Acaulospora (32.56%) followed by Claroideoglomus (18.60%). Homegardens had the highest spore density (7641.5 spore100 g− 1 dry soil) and the lowest was recorded in croplands (683.6 spore100 g− 1 dry soil). Woodlot had the highest root colonization (54.75%) followed by homegarden (48.25%). The highest isolation frequency (63.63%) was recorded for Acaulospora scrobiculata. Distribution of AMF species and diversity were significantly related to soil total nitrogen and organic carbon. The homegarden and woodlot AFP were suitable for soil AMF reserves and conservation.

“…AC-arbuscular colonization; VC-vesicular colonization; HC-hyphal colonization; similar letters denote not signi cant difference at p < 0.05.The hyphal colonization recorded in this study (44-71%) showed similar pattern of compared to a study byBirhane et al (2021) who have reported AMF colonization of church forests in northern Ethiopia which was in the range of 31-82%. Our results are much higher than hyphal colonization (18.6%-34%) reported from grassland ecosystems in the middle Awash basin in Ethiopia(Terefe et al, 2021) that could be due to the differences in plant species, soil physicochemical properties and soil management practices.In general, pattern of mean root colonization of HC (56.88%) was twice and four times higher than VC (24.25%) and AC (11.81%) colonization.…”

“…In Ethiopia, research works were undertaken on AMF species diversity and abundance in different land use types. To mention few, mycorrhizal status of different coffee shed trees in agro-forestry systems south west Ethiopia (Muleta et al, 2007;Channie and Assefa, 2013), dual function of AM fungi and rhizobia with Acacia polyacatha (Yohannes and Assefa, 2007), species diversity and population density of AMF in Acacia woodland ecosystems and agroforestry systems in central Shewa (Belay et al, 2013;Belay et al, 2015), species diversity and population density of AMF in Sidama agro-forestry systems (Dobo et al, 2016), AMF status of Erythrina brucei in different land use types in Ethiopia ( Berza et al, 2021) and species and population density of AMF in the highlands of northern Ethiopia (Birhane et al,2021).…”

In terrestrial ecosystems, arbuscular mycorrhizal fungi (AMF) helps land plants in nutrient uptake and protect them against abiotic and abiotic stresses. It is important to study the AMF-plant relationship to fully realize the bene cial potential to support establishment, growth and maintenance of mycorrhizal plants in different ecosystems. Therefore, the objective of this study was to determine the diversity, abundance and population densities of AMF and quantify root colonization of the indigenous trees in Munessa forest. To this end, composite soil samples and ne roots were collected from seven dominant indigenous trees within 10 m x10 m plots in the forest. AMF spores were extracted for taxonomic identi cation and root colonization with AMF structures was determined for each trees. A total of 39 AMF species (morphotypes) belonging to 10 genera were recovered. Glomus was the most dominant genus followed by Acaulospora. The highest genus richness was recorded from Croton macrostachyus (9). Mean AMF spore density was signi cantly different (p < 0.05) among indigenous trees, ranging from 860 spores/100 g of dry soil under Albizia shimperiana to 2830 spores/100 g of dry soil under Pouteria adol ifriedericii. The highest root hyphal colonization was observed in Millettia ferruginea (71%) and Podocarpus falcatus (64%), respectively. Albizia shimperiana was the least colonized tree (44%). AMF spore density was positively correlated with soil available phosphorus (p < 0.05). Extensive studies are required to select AMF inocula for plant growth promotion and recruitment of tree seedlings for plantation and, restoration of forest vegetation and rehabilitation of degraded and dry lands.

“…AMF diversity and distribution have been studied in different land uses, ecosystems and agroecologies in Ethiopia. AMF root colonization and spore density were documented in the dry afromontane forest, fragmented church natural forest and different land use types in northern Ethiopia [ 45 – 49 ]. AFPs have been widely practiced in south Ethiopia for enhancing crop production, water and energy use efficiency, and soil health.…”

The conversion of an agroforestry based agricultural system to a monocropping farming system influences the distribution and composition of arbuscular mycorrhizal fungi (AMF). The aim of this paper was to analyze AMF species diversity, spore density, and root colonization across different agroforestry practices (AFP) in southern Ethiopia. Soil and root samples were collected from homegarden, cropland, woodlot, and trees on soil and water conservation-based AFP. AMF spores were extracted from the soil and species diversity was evaluated using morphological analysis and root colonization from root samples. The AMF spore density, root colonization and composition were significantly different among the AFP (P < 0.05). In this study, 43 AMF morphotypes belonging to eleven genera were found, dominated by Acaulospora (32.56%), followed by Claroideoglomus (18.60%).

The distribution of AMF species and diversity were significantly related to soil total nitrogen and organic carbon. The homegarden and woodlot AFP were suitable for soil AMF reserve and conservation.
