Abstract Aims Melon Fusarium wilt, caused by Fusarium. oxysporum f. sp. melonis, is a severe soil-borne disease that reduces melon yield. Biological control approaches have been shown to be effective for the of wilt and could contribute sustainable development industry. Bacillus megaterium (BM) biocontrol strain has promote plant growth diseases. However, few studies examined mechanism which BM controls disease. Methods In this study, we investigated effect on plants, as well soil microbial communities, co-occurrence network, keystone taxa. Results Using pot experiment, showed incidence decreased from 68.33% (CK, inoculated with sterile water) 26.67% (inoculated BM), efficiency was 60.00%. field reduced 5.56% (naturally occurring) 1.67% after treatment, 69.44%. treatment also promoted plants increased yield 20.35%. The abundance potentially beneficial microbes (e.g., Flavobacterium, Nocardioides, Streptomyces, Chaetomium) pathogenic Alternaria, Aspergillus, Mortierella, Plectosphaerella) higher lower in than CK, respectively. Co-occurrence network complexity taxa OTU2869 (Pseudomonas), OTU3763 (Sphingobacterium), OTU2440 (Streptomyces) play key roles CK. Conclusions results our study indicated an agent increase altered composition taxa, indicating it alter community, decrease wilt.

Abstract Biochar and organic fertilizer are widely supported to maintain crop production sustainable development of agroecosystems. However, it is unclear how biochar alone or in combination regulate soil functional microbiomes their relationships ecosystem multifunctionality (EMF). Herein, a long-term (started 2013) field experiment, containing five fertilization treatments, was employed explore the effects applications on EMF (based 18 indicators productivity, nutrient supply, element cycling, microbial biomass) bulk rhizosphere [normalizing abundances 64 genes related carbon (C), nitrogen (N), phosphorus (P), sulphur (S) cycles]. Compared with single-chemical fertilization, inputs significantly enhanced most ecosystem-single functions and, particular, increased by 18.7–30.1%; taxa C-N-P-S cycles varying degree. The combined application showed better improvement these compared using them individually. Most populations soil, especially involved C degradation, nitrification, nitrate-reduction, P mineralization, S cycling positive associations at different threshold levels, which ultimately regulated pH availability. These results highlight strong links between agroecosystem functions, as well providing scientific support for inclusion agricultural services amendments. Graphical

This study explores agronomic management (AM) effects on soil parameters under diverse conditions. Investigating tillage practices (TP), nutrient (NM), crop rotation (CR), organic matter (OM), irrigation (IM), and mulching (MS), it aims to reveal impacts productivity, availability, microbial activity, overall health. Varied TP affect quality through compaction, porosity, erosion risk. Proper NM is vital for cycling, preventing imbalances acidification. CR disrupts pest cycles, reduces weed pressure, boosts recycling. OM enhances by influencing carbon, pH, fertility, water retention. Optimizing IM regulates content without inducing waterlogging. MS contributes content, retention, structure, temperature-moisture regulation, benefiting biota, aggregation, health agricultural productivity. The review emphasizes integrated nutrient, CR, management's positive impact fertility activity. Different variations production. Judicious implementation of these essential sustainable agriculture. synthesis identifies uncertainties proposes research directions optimizing productivity while ensuring environmental sustainability. Ongoing inquiry can guide a balanced approach between yields resilient stewardship future generations.

Using beneficial microorganisms, such as purple non-sulfur bacteria (PNSB), has shown enormous potential for improving plant growth and agricultural production. However, the full extent of their benefits interactions with practices is yet to be fully understood. The present study aimed investigate use PNSB in crop rotation practice, focusing on its impact rice yield. experiment was conducted over two cropping seasons, djulis grown between a crop. shows that treatment increased concentration 5-aminolevulinic acid (5-ALA) plants, indicating enhanced photosynthesis. Moreover, when combined rotation, remarkably improved soil fertility. These resulted substantial increases tiller numbers (163%), leaf chlorophyll content (13%), lodging resistance (66%), compared untreated plants. also higher productive tillers per hill (112%), average grain (65%), fertility (26%). This led yield shoot dry weight (15%), harvest index (37%). findings clearly suggest incorporation strategies can significantly augment crops. insights, pivotal sustainable cultivation, hold simultaneously tackle pressing issues global food security climate change.

Abstract Background Continuous cropping can reduce soil quality and affect rhizosphere metabolism, ultimately reducing crop yield. Crop rotation mitigate the damage caused by continuous cropping, but different patterns respond differently to metabolism. We investigated effects of on physicochemical properties, enzyme activities, microbial quantity, metabolism potato based a long-term field study from 2018 2022. The experiment was set up with following three treatments: ( Solanum tuberosum L.)-potato-potato-potato-potato (CK), potato-potato-potato-pea Pisum arvense L.)-potato (T1), potato-potato-potato-faba bean Vicia faba (T2). Results results showed that pea-potato (T1) bean-potato (T2) significantly improved properties enhanced activity, increased yield 21.19% 28.38%, respectively, compared crop. Non-targeted metabolomics analysis differential metabolites were mainly nucleotides, organic acids derivatives, flavonoids cropping. These are enriched in ABC transporter, purine pyrimidine phenylalanine pathways. Combined analyses legume-potato rotations quantity increasing tuber yields. In addition, correlation l -Tyrosine, Trans-Cinnamic acid, Guanine, Adenine) also strongly associated these measurements. Conclusions Therefore, we conclude modulate abundance function alter low molecular metabolite profile under conditions. Some important may play part cycling nutrients soil, making its better, raising activity enzymes, tubers. above indicate has positive effect soils.
