abstract in this study a greenhouse experiment was conducted to evaluate the role of acc deaminase enzyme on alleviation of salinity stress of canola plant. canola plants were exposed to pseudomonas fluorescens strain p12 which contains a rhizobacter capable of producing pseudomonas fluorescens in comparison with plants exposed to mutant pm12 unable to produce the required enzyme. the mutant wa...

Soil microorganisms directly participate in phosphorus (P) cycle, which turn affects crop yield and quality. However, how biological chemical parameters respond to mineral P fertilizer application rates rhizosphere soil remains unclear. Here, a pot experiment was conducted investigate the effects of different (0, 60, 120, 300 kg P2O5 ha−1) on properties bacterial community maize Mollisol. With ...

To boost crop yield on arable land, fertilizers have been extensively utilized. A country may become food-self-sufficient by using more chemical in agriculture, yet chemicals are harmful to the environment and living things. Biofertilizers organic substances that make use of microorganisms increase fertility soil, which helps safeguard soil's health also quality products. provide nutrients thro...

The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...
