Soil is a crucial component for plant growth, as it provides water, nutrients, and mechanical support. Various factors, such crop cultivation, microflora, nutrient addition, water availability, significantly affect soil properties. Maintaining health important, one approach the introduction of native organisms with multifaceted activities. In this study, effects four microbes (Trichoderma asperellum strain TAIK 1, Bacillus cabrialesii BIK3, Pseudomonas putida PIK1, otitidis POPS1) their consortia on health, incidence stem rot disease caused by Sclerotium oryzae in rice are evaluated. Upon bioagent treatment through seed or application, variations chemical properties were observed, viz., pH, Electrical Conductivity (EC), Organic Carbon (OC), available Nitrogen (SN), Phosphorus (SP), Potassium (SK), enzymes (urease, acid alkaline phosphatase, dehydrogenase), compared to untreated soils. The treated seeds bioagents resulted significant increase height (39.16%), number panicles (30.29%), average grain yield (41.36%) over control plants. Under controlled conditions, bioagents-treated plants showed 69.37% reduction disease. findings study indicate positive correlation between growth well highly negative association severity. results suggest that using management strategy can enhance productivity while reducing reliance interventions. These provide valuable insights development sustainable agricultural practices promote management.

Charcoal rot caused by Macrophomina phaseolina is one of the most devastating diseases that cause severe yield loss in Gloriosa superba cultivation. Plant growth-promoting rhizobacteria (PGPR) are extensively harnessed as biocontrol agents due to their effectiveness combating a wide array plant pathogens through multifaceted approach. The present study delved into mechanisms underlying its ability inhibit root pathogen and capacity promote growth G. superba, commonly known glory lily. PGPR isolated from rhizosphere lily were subjected vitro assessments using dual plate technique. Bacillus subtilis BGS-10 B. velezensis BGS-21 showed higher mycelial inhibition (61%) against M. phaseolina. These strains also producing indole-3-acetic acid, siderophore, ammonia, amylase, cellulase, pectinase, xylanase, lipase chemicals. Genome screening revealed presence antimicrobial peptide genes such Iturin (ituD gene), surfactin (srfA sfp genes) along with mycolytic enzyme β-1,3-glucanase. Further, secondary metabolites bacterial secretome was identified gas chromatography-mass spectrometry (GC/MS) analysis. Notably, pyrrolo[1,2-a] pyrazine-1,4-dione, hexahydro-3-(2-methylpropyl), 9 H-pyrido[3,4-b] indole L-leucyl-D-leucine exhibited highest docking score enzymes responsible for cell wall degradation. Under glasshouse conditions, tuber treatment soil application talc-based formulation suppress incidence minimal disease 27.78% over untreated control. Concurrently, there notable induction defense-related enzymes, including peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia-lyase (PAL), Therefore, it can be concluded play significant role fortifying plant's defense pathogen.
