Plant growth-promoting bacteria (PGPB) are an effective tool for improving nutrients in agricultural systems; however, their efficacy depends on successful colonization soils. To address this challenge, biochar has been identified as material enhancing soil ecosystem services and can serve a protective PGPB. However, the impact of PGPB health indicators plant growth remains poorly understood. This study aimed to evaluate effects chemical biological properties cowpea. We used from bean husk (BHB) grape fermentation residue (GFB) Bradyrhizobium elkanii USDA 76 (BRA), Burkholderia cepacia ATCC 25416 (PRB), or Rhizobium altiplani BR10423 (RHI). BHB PRB stimulated cowpea growth, while GFB promoted phosphatase activity. Overall, different combinations PGPR increased pH, phosphorus, potassium, organic carbon content, urease activity, but did not affect microbial biomass β-glucosidase activities. The biochars inoculated with BRA showed highest productivity. For example, plants subjected + treatment exhibited 3.85-fold increase productivity compared additional that involved use commercial peat. demonstrated positive effect enzymatic nutrient suggesting sustainable alternative fertilizers, especially poor These findings highlight potential environmentally carrier addressing issue waste reuse.

Rhizosphere microbiome exerts a significant role in plant health, influencing nutrient availability, disease resistance, and overall growth. Establishing robust efficient nodulation process is essential for optimal nitrogen fixation legumes like soybeans. Different soybean genotypes exhibit variations their rhizosphere microbiome, potentially impacting through nodulation. However, detailed understanding of how specific influence microbial communities patterns remains limited. Our study aims to investigate the relationship between abundance growth four genotypes. We evaluated parameters, including biomass, leaf area, stomatal conductance, identified genotypic differences Specifically, PI 458505 603490 exhibited high levels nodulation, while 605839A 548400 displayed low 16S rRNA gene amplicon sequencing revealed diverse bacterial rhizosphere, with Proteobacteria as dominant phylum. High-nodulation harbored more enriched Actinobacteria Acidobacteriota, low-nodulation showed higher abundances Firmicutes Planctomycetota. Alpha beta diversity analyses confirmed distinct community structures high- groups. findings suggest that significantly influences highlighting potential genotype-driven strategies enhance plant-microbe interactions improve productivity.
