Arbuscular mycorrhizal fungi (AMF) are beneficial for plant development and help absorb water and minerals from the soil. The symbiosis between these fungi and plant roots is extremely important and could limit crop dependence on fertilizers. The aim of this study was to evaluate the influence of AMF on tomatoes (Solanum lycopersicum L.), based on important agronomic traits of vegetative biomass, production, and fruits. The experiment was conducted in high tunnels, using 12 tomato genotypes under three different treatments: T1, control, without fertilizer and mycorrhizae colonization; T2, fertigation, without mycorrhizae colonization; and T3, arbuscular mycorrhizal fungi (AMF), seedling roots being inoculated with specialized soil-borne fungi. Plant growth, yield and fruit parameters indicated better results under mycorrhizal treatment. Root colonization with fungi varied significantly depending on the treatment and genotype, with a variation of 6.0–80.3% for frequency and 2.6–24.6% for intensity. For a majority of characteristics, the mycorrhization (T3) induced significant differences compared with the T1 and T2 treatments. In addition, AMF treatment induced a different response among the genotypes. Among the elements analyzed in the soil, significant differences were observed in phosphorous levels between planting the seedlings and after tomato harvesting and clearing of the plants. The results suggest that reducing fertilizers and promoting the symbiotic relationships of plants with soil microorganisms may have beneficial consequences for tomato crops.

“…decreased with the application of P, while the addition of N did not change the composition of fungal mycorrhizal structures. NPK application can have a negative effect on mycorrhizal colonization [36] and species diversity decreased following the application of inputs in shallow soil. The study [37] states that arbuscular mycorrhizae especially sporulate at depths of 50-70 cm and the diversity and richness of species decreases with soil depth.In general, fertilizers have a negative effect on the colonization of mycorrhizae, following a long-term study of differentiated fertilization, both organic and mineral, has produced a negative effect on mycorrhizal fungal communities.…”

Excessive application of chemical fertilizers and other agrochemicals can cause large imbalances in soils and agricultural ecosystems. In this context, mycorrhizae represent a viable solution to mitigate these negative effects. Arbuscular mycorrhizae are vital symbionts due to the multiple benefits they bring to both crops and the entire agroecosystem. The main purpose of this study was to observe whether differentiated fertilization has an influence on mycorrhizal colonization patterns in corn. Observed frequencies and intensities of colonization varied widely between phenophases and treatments, with 20% variation for frequency and 14% for intensity, which implies the constant development of both partners during the vegetation period. Arbuscules and vesicles were present in all development stages, but the overall mean was lower than 4% for arbuscules and 1% for vesicles in the analyzed root fragments. Intensity was highly correlated with frequency of colonization compared with arbuscules, where the coefficient was 0.54, and vesicles, with a coefficient of 0.16. Both PCA and NMDS provided good graphical solutions, with a high resolution due to explained variance and good spatial position of vectors. The use of mycorrhizal maps permits the full exploration of colonization patterns and fungal strategy, and the assessment of mycorrhizae-free areas. For the untreated variant, the strategy was oriented toward a longitudinal colonization followed by an irregular development of hyphae with multiple non-colonized areas. Treatment acts to stimulate the appearance of mycorrhizal spots, which further develop radially.

“…Soil properties are an important axis for evaluating soil quality of arable land (Bünemann et ). Thus AMF community structure in non-rhizosphere soil has also attracted attention (Luo et al 2021). Moreover, our weed control treatment has been lasted for 14 years at the sampling date, indicating that weed control may exert a long-term impact on soil environment.…”

“…Such practices are variable and have either positive (Guzman et al 2021;Xiao et al 2022) or negative (Edlinger et al 2022) effects on AMF communities. These effects of agricultural practices could be originated induced by from the both direct or indirect effects on the soil environment and host plants (Luo et al 2021;Ngosong et al 2010). In the cropping systems, complex interactive relationships between both AMF and weeds were previously observed (El Omari and El Ghachtouli 2021; Jordan et al 2000), in which AMF may have some in uence on the weeds' community (Rinaudo et al 2010).…”

Rational weed control in arable land is a key contributor to food security and sustainable agricultural development. However, little is known about how weed control practices affect the root-associated arbuscular mycorrhizal fungi (AMF), especially in rice-wheat cropping systems. Here, the effects of different weed control measures on AMF community structure, wheat yield and soil properties were determined based on a long-term weed control experiment established since 2001 in a rice-wheat annual double cropping system. The weed control treatments include: (ⅰ) control (CK): No weeding; (ⅱ) manual weeding + herbicide application (MH); (ⅲ) Hindering seeds dispersed from water + herbicide application (WaH); (ⅳ): Hindering seeds dispersed from water + manual weeding (WaM); (ⅴ) Hindering seeds dispersed from water + manual weeding + herbicide application (WaMH). Results demonstrated that weed control markedly affected soil properties, shifted AMF community structure (diversity and composition), and notably increased wheat yield by 52.6%-62.2% compared with CK. The values of Pielou evenness index, Shannon-Weiner index and Simpson’s index were significantly lower under MH compared with CK. The Mantel test analysis indicated that AMF diversity was dominantly controlled by both total nitrogen and soil organic carbon. Similarly, AMF composition was markedly affected by soil water content, total nitrogen, nitrate nitrogen, ammonium nitrogen, and microbial biomass nitrogen. Mantel test also revealed that wheat yield was significantly correlated to AMF composition and Pearson correlation analysis also showed that some key indicator taxa were significantly correlated with wheat yield, suggesting that the composition of AMF community might play an important role in wheat yield formation. In addition, redundancy analysis (RDA) showed that soil properties and wheat yield were closely related to AMF community characteristics. Taken together, our findings suggest that weed control can mediate the relationships among soil quality, AMF community and wheat yield, providing valuable guidance for integrated weed management in the Yangtze River basin regions in China.
