“…Considering earthworms, their ecosystem services and their microbes in agricultural practices holds a big potential for the agriculture of the future (Singh et al, 2020). The microbial community of vermicompost, as a product obtained mainly from organic litter earthworm casts, clearly differs from potting soil, with especially higher proportions of Bacillus (5.22 vs. 0.02%).…”

Understanding the Impact of Cultivar, Seed Origin, and Substrate on Bacterial Diversity of the Sugar Beet Rhizosphere and Suppression of Soil-Borne Pathogens

The rhizosphere microbiome is crucial for plant health, especially for preventing roots from being infected by soil-borne pathogens. Microbiota-mediated pathogen response in the soil-root interface may hold the key for microbiome-based control strategies of phytopathogens. We studied the pathosystem sugar beet-late sugar beet root rot caused by Rhizoctonia solani in an integrative design of combining in vitro and in vivo (greenhouse and field) trials. We used five different cultivars originating from two propagation sites (France, Italy) with different degrees of susceptibility towards R. solani (two susceptible, one moderately tolerant and two cultivars with partial resistance). Analyzing bacterial communities in seeds and roots grown under different conditions by 16S rRNA amplicon sequencing, we found site-, cultivar-, and microhabitat-specific amplicon sequences variants (ASV) as well as a seed core microbiome shared between all sugar beet cultivars (121 ASVs representing 80%-91% relative abundance). In general, cultivar-specific differences in the bacterial communities were more pronounced in seeds than in roots. Seeds of Rhizoctonia-tolerant cultivars contain a higher relative abundance of the genera Paenibacillus, Kosakonia, and Enterobacter, while Gaiellales, Rhizobiales, and Kosakonia were enhanced in responsive rhizospheres. These results indicate a correlation between bacterial seed endophytes and Rhizoctonia-tolerant cultivars. Root communities are mainly substrate-derived but also comprise taxa exclusively derived from seeds. Interestingly, the signature of Pseudomonas poae Re*1-1-14, a well-studied sugar-beet specific biocontrol agent, was frequently found and in higher relative abundances in Rhizoctonia-tolerant than in susceptible cultivars. For microbiome management, we introduced microbial inoculants (consortia) and microbiome transplants (vermicompost) in greenhouse and field trials; both can modulate the rhizosphere and mediate tolerance towards late sugar beet root rot. Both, seeds and soil, provide specific beneficial bacteria for rhizosphere assembly and microbiota

“…Nutrient content in raw materials affect the speed of the process of composting [38]. Vermicompost has a surface that is wide enough for beneficial microbial activity and produces humus which functions to increase soil aggregation so that it can improve the availability of nutrients for plants as well as increase soil fertility [39] and will further improve plant health and growth [40]. Low growth occurred in the treatment without giving vermicompost on all growth parameters at all ages of observation.…”

Shallot is one of an important vegetable in Indonesia. The yield of the crop is often constrained by low and unbalanced nutrient supply in the soil. The application of vermicompost based on soybean husk and cow manure can increased nutrient supply in the soil. This research aimed to obtain the optimum vermicompost formulation and doses based on soybean husk and cow manure on shallots. This research is a field that arranged Randomized Complete Block Design (RCBD) with 1 factor (vermicompost formulation (V) that consisted 4 doses for each treatment and 3 replication was applied. The treatment consisted of vermicompost formulation (V): 100% soybean husk, 100% cow manure, 50% soybean husk: 50%: cow manure, 75% soybean husk: 25%: cow manure and 25% soybean husk: 75%: cow manure. Each treatment consisted of four doses: without application, 5, 10, 15 t. ha-1, so the total treatment was 20 level. Data were analyzed using the least significant difference (LSD) test. The result indicated that vermicompost formulation gave significant effect on all of observation parameters on the growth and yield. The lowest response of shallots occurred in the treatments without vermicompost application on all formulations, and the highest was in the 100% soybean husk formulation at a dose of 15 t. ha-1.

“…Since then, numerous studies have been conducted to evaluate the use of vermicomposting for sludge reduction and stabilisation. It is an environment-friendly technology in which earthworms interact with microorganisms, under thermophilic and aerobic conditions, allowing the stabilisation of organic matter and modifying its physical and biochemical properties (Singh et al, 2020;Liu et al, 2012;Dominguez, 2004). Huang and Xia (2018) have studied the performance of vermicomposting and demonstrated the enhancing effect of earthworms on excess sludge treatment.…”

In the present study, vermicomposting of sewage sludges and their application in agriculture have been investigated. The impact of Eisenia fetida earthworms on the stabilization of these sludges during 7, 14 and 21 days was assessed. The final product was applied as soil amendment (set-1) to evaluate the effects on vegetative parameters (Chlorophyll, carotenoid, number of nodules, leaf weight, and plant height) of Phaseolus vulgaris.L bean. In the second test (set-2), the amendment was made with raw sludge. In the third test (set-3), the worms were added to the raw sludge at the time of spreading and left during the whole period of beans growth. In order to identify and better understand the behavior and role of worms with regard to sludge, their growth (weight and length), some pathogens and physico-chemical parameters were assessed during the vermicomposting. Results showed significant increase of earthworm weight of 10.62, 23.89 and 35.72 % after 7, 14 and 21 days of sludge vermicomposting, respectively, which explain their acclimatization . The vermicomposting caused a decrease of feacal coliforms number and organic matter (OM), an increase in electrical conductivity (EC) and stabilization in pH. Furthermore, significant differences were obtained for all plants vegetative parameters in soil amended with vermicomposts, compared to the control (unamended soil). Indeed, a significant increase of the chlorophyll level (a, b) was noted in the beans having undergone sludge spreading. However, worm-stabilized sludge for 7 days (set-1) showed the highest chlorophyll a and b levels about 16.1 and 24.64 μg/g, respectively, against 10.13 and 4.38 μg/g in the control. For the carotenoid, a significant decrease was observed compared to the control. Our experiments have also showed that the application of vermicomposted sludge significantly increases the number of nodules, leaf weight and plant height of Phaseolus Vulgaris L . snap beans .
