The effect of plant growth-promoting rhizobacteria (PGPR) on seed germination, seedling growth and yield of field grown maize were evaluated in three experiments. In these experiments six bacterial strains include P.putida strain R-168, P.fluorescens strain R-93, P.fluorescens DSM 50090, P.putida DSM291, A.lipoferum DSM 1691, A.brasilense DSM 1690 were used. Results of first study showed seed I...

this experiment was carried out to evaluate the effect of rhizobium strains and plant growth promoting rhizobacteria (pgpr) on dry matter partitioning and some growth parameters of chickpea (cicer arietinum l.) arman cultivar. this research was conducted as split plot based on complete random block design at zanjan university research farm. irrigation levels (optimum irrigation during season gr...

Salinity is one of the most important abiotic stresses that limit crop growth and productivity. This study focuses on the effects of different strains of plant growth promoting rhizobacteria (PGPR) on the physiological responses of two wheat cultivars under normal and salt stress conditions. The wheat cultivars selected include one which is tolerant to salinity (Kavir) and one which is sensitiv...

This study investigated the effects of vermicompost fertilization with complementary microbial nutrition on plant growth, yield, and fruit quality organically grown strawberry “Monterey” cultivar. Along vermicompost, five different fertilizers containing plant-growth-promoting rhizobacteria (PGPR) arbuscular mycorrhizal fungi (AMF) were used as nutrition. Here, we examined growth parameters, we...

With the development of marine biorefinery concept, utilisation algal waste during industrial processing as well some “green tide” biomass has become an important research topic. In this work, a single-step microwave process was used to hydrolyse Laminaria japonica (LJW) and Enteromorpha prolifera (EP), producing growth medium suitable for microbial cultivation. The contained range mono- polysa...

Abiotic stresses are major constraints for plant growth, crop yield and global food security. Plant physiological, biochemical molecular processes highly affected under unfavorable environmental conditions, resulting in substantial losses to productivity requiring an immediate response. stress resistant growth-promoting rhizobacteria (PGPR) a profitable sustainable solution because of their eff...

BACKGROUND The present study investigated the effect of seven Bacillus-species plant-growth-promoting rhizobacteria (PGPR) seed treatments on the induction of disease resistance in cowpea against mosaic disease caused by the blackeye cowpea mosaic strain of bean common mosaic virus (BCMV). RESULTS Initially, although all PGPR strains recorded significant enhancement of seed germination and se...

Plant growth promoting rhizobacteria (PGPR) are diverse, naturally occurring bacteria that establish a close association with plant roots and promote the growth and immunity of plants. Established mechanisms involved in PGPR-mediated plant growth promotion include regulation of phytohormones, improved nutrient availability, and antagonistic effects on plant pathogens. In this study, we isolated...

The quest for enhancing agricultural yields due to increased pressure on food production has inevitably led the indiscriminate use of chemical fertilizers and other agrochemicals. Biofertilizers are emerging as a suitable alternative counteract adverse environmental impacts exerted by synthetic facilitate overall growth yield crops in an eco-friendly manner. They contain living or dormant micro...
