The usage of novel Plant Growth-Promoting Rhizobacteria (PGPR) as bioinoculant is a good opportunity for ecological farming practices to improve soil condition, quality of grain, crops’ yield and biodiversity conservation. The purpose of recent research was focused to examine, isolate and characterize PGP bacteria that colonize the rhizosphere for the duration of the maize plant's seedling. For this purpose, 14 samples of soils and roots in the maize rhizosphere were collected from rock phosphate area of Hazara, Pakistan. Forty morphologically natural bacterial colonies have been extracted and tested for their PGP innovations and biocontrol residences and further recognized as plant production advancing rhizobacteria. To find the effective PGPR strains with numerous activities, an aggregate of 150 bacterial colonies were sequestered from different rhizospheric soils of the Hazara Pakistan rock phosphate area. These tested bacterial strains were subjected to biochemical description and in vitro screening for their plant growth-promoting qualities like generation of indole acetic acid (IAA), alkali (NH3), hydrogen cyanide (HCN), siderophores, catalases, proteases and pectinases. All the isolates of rhizobacteria showed IAA producing capacity, as well as found positive for catalase and HCN. The above results suggested that, in addition to biocontrol marketers, PGPR could be used as biofertilizers to substitute agro-chemicals in order to increase crop production. These microorganisms can therefore be further developed and used for greenhouse and discipline packages. |
