abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

An assessment of roles of rhizospheric microbial diversity in plant growth is helpful in understanding plant-microbe interactions. Using random combinations of rhizospheric bacterial species at different richness levels, we analysed the contribution of species richness, compositions, interactions and identity on soil microbial respiration and plant biomass. We showed that bacterial inoculation ...

in the present study, we aimed to screen indigenous rhizospheric bacillus strains, capable of producing antiphytopathogenic and plant growth promoting traits. isolate cts-b19 and cts-g24 exhibited quite noticeable antagonistic activity initially against fusarium oxysporum f. sp. ciceri and rhizoctonia bataticola, and, later, against a panel of phytopathogens. partial 16s rrna sequence analysis ...

One of the important and necessary practices for improving nutrients availability in sustainable agriculture is using microorganisms. Beside the negative effects of chemical fertilizers on the soil and human health, plant growth promoting rhizobacteria are known as an alternative to supply the organic nutrients of plants during the past two decades. Enriching soil fertility by eco-friendly meth...

Abstract Many agricultural researches have been performed to improve soil productivity. Nitrogen (N) and Phosphorus (P) are essential elements which are utilized by the plants in large amounts. Phosphorus can be provided by applying chemical fertilizers.

The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated with soil microorganisms. Such bacteria which can grow in the rhizosphere region as well as plant roots and enhance the plant growth are referred as plant growth promoting rhizobacteria (PGPR). Plant Growth Promoting Rhizobacteria promotes growth of plants through direct and indirect mecha...

Beneficial soil microorganisms influence nutrient recycling, fertility, plant growth, and productivity reduce chemical fertilizer application. This study aimed to isolate bacteria from non-agricultural soils in the Al-Ahsa region characterize with best biostimulating characteristics at physiological, biochemical, molecular level. DPM17, a bacterial isolate, promotes growth through phosphate sol...

trichoderma spp. are known as efficient plant growth promoting agents. hence, enrichment of soil by appropriate population of trichoderma is useful and important for effective plant growth promote. present study aimed to investigate the plant growth promoting effects of five strains of the genus trichoderma species include: trichoderma harzianum tr6, t. harzianum t22, t. asperellum t34, t. atro...

Rhizosphere is a wealthy location of microbes, ecological niche and should be explored for potential plant growth promoting rhizobacteria (PGPR), which developing as bioinoculants for interact with plant roots and enhancement of yield of crop plants. There are several plant growth promoting rhizobacterial (PGPR) inoculants that seems to promote plant growth through different mechanism such as I...
