“…2c-f). These results are consistent with those obtained by Kavadia et al (2020) and Ren et al (2020), who demonstrated that the impact of water regime and AMF inoculation on fungal-community composition and diversity depended on soil history, soil conditions, AMF species, plant species, and plant growth stage. In our study, the soil on the Loess Plateau has poor nutritional status; thus, nutrients may be an important factor that limiting AMF richness and diversity.…”

Adaptive management of arbuscular mycorrhizal fungi (AMF) provides a new option for sustainable agriculture. Previous studies showed that the functional role of AMF was frequently dependent on soil moisture and planting densities in the semiarid environment. However, a systematic quantitative analysis of the effects of AMF inoculation on crop productivity and soil quality needs to be investigated. Therefore, a 2-year field experiment was conducted to test the inoculation effects of AMF (Funneliformis mosseae) on wheat (Triticum aestivum L.) productivity and soil quality in the semiarid Loess Plateau under two water regimes (irrigated and non-irrigated) with seven plant densities in year 2017 and 2018. Our results showed that in the non-irrigated treatment, inoculation with AMF greatly increased dryland wheat aboveground biomass, crop productivity, water use efficiency, rhizosphere soil organic carbon, soil organic carbon to total nitrogen ratio, microbial biomass carbon to nitrogen ratio, and microbial biomass carbon and nitrogen (P < 0.05) compared to the non-inoculated treatment. For example, compared with non-inoculated plants, the grain yield in the non-irrigated but inoculated plants increased by 59 ± 28% in 2017 and 36 ± 2.8% in 2018, and the water use efficiency for grain increased by 53 ± 26% and 25 ± 12% in 2017 and 2018, respectively. However, the different results were observed under irrigated conditions. In the irrigated treatment, AMF inoculation had a slightly positive effect on grain yield and soil quality at low plant density but was negative at higher plant densities. Here we demonstrated for the first time that AMF inoculation significantly improved wheat productivity and soil quality, while its effects were conditionally density-and moisture-dependent. Therefore, optimizing AMF addition is an effective measure for sustainable agricultural development and provides a novel solution for the management of soil degradation management in the semiarid area of the Loess Plateau.

“…For two species, maize and chickpeas, we have explored how integrated strategies in plant breeding can include soil microbial communities studies. Molecular fingerprinting showed that arbuscular mycorrhizal fungi (AMF) diversity is partially associated to maize and Cyprus chickpea landraces' productivity and this is related with the plant genotype [70], shedding light on how plant-microbe interaction can be harnessed in different species.…”

Agroecology calls for a global approach, integrating scientific, practical, and advocacy dimensions, to redesign agricultural systems based on ecological and socio-cultural processes and emphasizing biodiversity. This review is grounded on the results of DIVERSIFOOD, a European H2020 multi-actor research project, and explores the concept of cultivated diversity using various dimensions relevant to foster sustainable organic food systems and agro-ecological transition. From the evaluation of underutilized genetic resources and forgotten crops, DIVERSIFOOD has proposed plant breeding strategies, on-farm experimentation, and statistical tools to create new populations, landraces, and organic cultivars with intra-varietal diversity. The added value of Community Seed Banks and forms of collective seed management in Europe have been described in terms of goals and activities, and their value for improving seed regulations, treaties, and genetic resources management is discussed. In the context of the current agro-food system characterized by standardization, DIVERSIFOOD raised awareness of qualities of ‘biodiverse food systems’ in which all actors have a role to play. It highlighted the critical capacity to preserve a diversity of cultural values embodied in ‘biodiverse products’, thereby involving consumers in collective strategies for reviving diversity, and empowering all actors of organic food systems to really and efficiently implement research within their farms and networks.

“…In the recent era, climate change had adverse impacts on crop productivity and economic returns from agricultural lands. Water scarcity, drought severity and extreme temperatures have reduced moisture levels in soil profile that alter physiology of the crops resulting in low growth and yield [1]. Thus, for maintaining global food security, it is very important to focus on research to mitigate drought Plants 2020, 9, 1629 2 of 21 severity.…”

Drought is a major constraint in drylands for crop production. Plant associated microbes can help plants in acquisition of soil nutrients to enhance productivity in stressful conditions. The current study was designed to illuminate the effectiveness of desert rhizobacterial strains on growth and net-return of chickpeas grown in pots by using sandy loam soil of Thal Pakistan desert. A total of 125 rhizobacterial strains were isolated, out of which 72 strains were inoculated with chickpeas in the growth chamber for 75 days to screen most efficient isolates. Amongst all, six bacterial strains (two rhizobia and four plant growth promoting rhizobacterial strains) significantly enhanced nodulation and shoot-root length as compared to other treatments. These promising strains were morphologically and biochemically characterized and identified through 16sRNA sequencing. Then, eight consortia of the identified isolates were formulated to evaluate the growth and development of chickpea at three moisture levels (55%, 75% and 95% of field capacity) in a glass house experiment. The trend for best performing consortia in terms of growth and development of chickpea remained T2 at moisture level 1 > T7 at moisture level 2 > T4 at moisture level 3. The present study indicates the vital role of co-inoculated bacterial strains in growth enhancement of chickpea under low moisture availability. It is concluded from the results that the consortium T2 (Mesorhizobium ciceri RZ-11 + Bacillus subtilis RP-01 + Bacillus mojavensis RS-14) can perform best in drought conditions (55% field capacity) and T4 (Mesorhizobium ciceri RZ-11 + Enterobacter Cloacae RP-08 + Providencia vermicola RS-15) can be adopted in irrigated areas (95% field capacity) for maximum productivity of chickpea.
