“…These results were identical to those of Tadesse Chanie (2006) in South Western Ethiopia. The number of mycorrhizal species may increase after using the bait technique (Sghir et al, 2013). Basing in composition, species richness, diversity and dominance of the AMF morphospecies spores Lopes et al (1983) recorded 27 coffee production systems from Brazil; 10 AMF morphospecies was isolated in five coffee production systems of Coffee arabica in Yemen.…”

Objective: This study describes the status of mycorrhizal fungi in coffee (Coffea arabica) in the Yemeni ecosystems. Methodology and results: Soil samples were extracted from the rhizosphere of the coffee tree groves in several regions of Yemen. The frequency and the level of colonization of the arbuscular mycorrhizal fungi (AMF) inside the root bark were measured by assigning an index of mycorrhization from 0 to 5 (Derkowska et al., 2008). The results showed that the AM fungal colonization structures were hyphae, coils and vesicles. The mycorrhizal frequency and intensity reached respectively 100 and 48 % in the Taiz 2 site. The highest spore density was in the order of 100 spores/100 g of soil and the genus Glomus was dominant. The tentative identification test of VAM (Vesicular Arbuscular Mycorrhizae) species, isolated from the rhizosphere of the coffee trees, revealed the presence of five fungal species:, Glomus proliferum, G. etunicatum, Acaulospora sporocarpia, Acaulospora sp.1, Archeospora sp. 1, Scutellospora nigra. Conclusion and application of results: In all the studied sites the coffee roots were mycorrhized. These results demonstrate the existence of opportunities for the application of controlled mycorrhization in the coffee Seedlings nurseries.

“…Variables densities were reported in sludge soil of different sites (El Gabardi et al 2019d), and in rhizospheric soil of bean as a function of different compost doses addition (El Gabardi et al 2019) or of three crops bean, wheat, and grass land receiving compost amendment (Valerini et al 2009). Morphological identification of AMF spores collected from different growing substrates showed the presence of 12 species, and the predominance of the genus Glomus which was also encountered in the rhizospheric zone of Citrus (Artib et al 2016), Carob tree (Talbi et al 2015), oleaster (Sghir et al 2013), date palm tree (Sghir et al Effect of soil composition on the growth and yield of tomato plants 2014), beans (El Gabardi et al 2019e), phosphate laundered sludge (El Gabardi et al 2019b), and from soil sites adjacent to Khouribga phosphate mine (El Gabardi et al 2019a).…”

The study aims to evaluate the eﬀect of endomycorrhizal inoculum (arbuscular mycorrhizal fungi), phospho-compost and phosphate sludge in single (M, PC, PS) or dual combinations (PC+M, PS+M, PS+PC) compared to agricultural and Mamora soils (A and S) on the growth, ﬂowering, and yield of tomato plants. Among the studied treatments, the substrates containing 5% of phospho-compost combined with endomycorrhizal inoculum (PC+M) gave the most positive eﬀect followed by phospho-compost (PC) and endomycorrhizal inoculum (M). In response to PC+M substrate, tomato plant height, the number of leaves and ﬂowers attained 90 cm, 30, and 25, respectively. In substrates PC and M, tomato plants showed a height of 85 and 75 cm, leaves number of 30 and 19 leave/plant and number of ﬂowers of 21, and 19 ﬂower/plant. An optimal yield with (12 fruits/plant) was recorded in tomato plants grown on the substrate amended with bio-inoculant (AMF) and phospho-compost at a rate of 5%. In terms of qualitative parameters, the highest fresh and dry weight of aerial plant parts and root system were recorded in tomato plants grown in culture substrate incorporating 10 g of endomycorrhizal inoculum and 5% of phospho-compost reaching respectively103.4 g, 34 g 90.1 g, 28.9 g as compared to 87, 51, 23 and 24.1 g noted by tomato plants on the substrate with phospho-compost (5%) (PC). The highest mycorrhization parameters (frequency (F), intensity of mycorrhization (M), average arbuscular content (A), average vesicular content (V), average intraradicular spore content (S)) were found in the roots of tomato plants growing on substrates amended with 5% phospho-compost plus 10 g of endomycorrhizal inoculum, with percentages of 100% F, 61% M, 40.67% A, 18.36% V, and 56.9% S.

In Chad, rice is grown for its starchy seeds or caryopses, but is also for consumption in the form of seeds pasta with soup. However, little or no work has been conducted in Chad to assess the composition of endomycorrhiza community inhabiting the plant rice rhizospheres. Hence, the main objective of this study was to investigate on native endomycorrhiza that are efficient to establish a symbiotic relationship with two rice varieties in the Sahelian zone in Chad. Two rice varieties were grown in a pot experiment on composite soils samples from Laï, Kelo, Kolobo and N’Djamena for 3 months. Parameters such as mycorrhizal frequency, intensity, specific density and richness were determined following to the standard methods. After spore extraction, species description and characterization were obtained through the informations provided by the International Vesicular Mycorrhizal fungi collection (INVAM): http://invam.caf.wv.edu/fungi/taxonomy/species ID.htm. The highest specific endomycorrhizal density (97.3%) and richness (11%) were registered respectively at kelo, Laï and Kolobo. The endomycorrhizal frequency and intensity were respectively between 4.33-7.33% and 0.8-2.9% for the two rice varieties. Eleven endomycorrhiza species belonging to six genera were identified from different soil samples. These include Septoglomus (S. constrictum, S. deserticola); Rhizophagus (R. aggregatus, R. fasciculatus, R. intraradices); Acaulospora (A. lacunosa, A. rugosa, A. trappei); Claroideoglomus lamellosum; Glomus pansihalos and Diversispora epigae. S. constrictum was the most dominant and frequent species found in all the soil sampling sites, while R. aggregatus was the less frequently encountered specimen. The lowest macorrhizal richness and frequency obtained is a proof that cultivation of rice dependent on endomycorrhiza in this zone. The multi-native endomycorhiza spores identified are the active principle to be included in the bioinoculants production in order to increase and improve the production of rice in the south of Chad.
