Plant growth promoting rhizobacteria (PGPR) are beneficial bacteria which have the ability to colonize the roots and either promote plant growth through direct action or via biological control of plant diseases (Kloepper and Schroth 1978). They are associated with many plant species and are commonly present in varied environments. Strains with PGPR activity, belonging to genera Azoarcus, Azospi...

Bacteria and plant derived volatile organic compounds have been reported as the chemical triggers that elicit induced resistance in plants. Previously, volatile organic compounds (VOCs), including acetoin and 2,3-butanediol, were found to be emitted from plant growth-promoting rhizobacteria (PGPR) Bacillus subtilis GB03, which had been shown to elicit ISR and plant growth promotion. More recent...

In the present scenario, demand for food and nutrient has increased due to population growth. Ascribable industrialization urbanization, a very small area of productivity land is available maintenance life process. Agricultural growth depends upon microbial in soil over last few years. plant promoting rhizobacteria turned out be most efficient tool sustainable agriculture. PGPR, exert its effec...

application of biofertilizers is a crucial technique for reducing catastrophic effects of irregular utilization of chemical fertilizers. this experiment was carried out to evaluate the effects of rhizobium strains and plant growth promoting rhizobacteria (pgpr) on dry matter partitioning and some growth parameters of chickpea (cicer arientinum l.), arman cultivar. this research was conducted as...

in order to study the qualitative and quantitative yield and some agronomic characteristics of sunflower (helianthus annus l.) in response to seed inoculation with pgpr under various levels of nitrogen fertilizer, a factorial experiment was conducted based on a randomized complete block design with three replications in field experimental university of mohaghegh ardabili during growing season o...

effects of arbuscular mycorrhizal fungus (glomus mossea ca) and plant growth promoting rhizobacteria (pgpr) of bacillus pantea and psedomonas putida were evaluated on growth parameters of osteospermum (osteospermum hybrida ‘passion mix’) under different watering conditions (field capacity, two and one third of field capacity). arbuscular mycorrhizal fungus (amf) and pgpr were applied as single ...

to date there is not progress commercially production and large scale application of pgpr in agriculture. one reason for limited commercial use of pgpr is variability, inconsistency and irreproduciblility of results between laboratory, greenhouse, and field trials. these problems with pgpr arises from variation in crops and cultivars, the physical, chemical and biological composition of  soils,...
