ABSTRACT In the composition of soil microbiome, there are numerous microorganisms capable promoting plant growth, better known as growth-promoting microorganisms. The study aimed to determine effects multifunctional microorganisms, alone or in combination, on shoot, root, and total biomass production, gas exchange, macronutrient content, yield components, grain corn plants. experiment was carri...
Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. In search of efficient PGPR strains with multiple activities, a total of 150 bacterial isolates belonging to Bacillus, Pseudomonas, Azotobacter and Rhizobium were isolated from different rhizospheric soil of chick pea in the vicinity of Allahabad. These test isolates were bi...
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...
To identify effective ways of increasing the yield crops grown in nutrient-poor calcareous soils, combined effects biochar addition and inoculation with plant growth promoting rhizobacteria (PGPR) arbuscular mycorrhizal fungi (AMF) on wheat soil properties were investigated under rhizobox conditions. Measured included pH, electrical conductivity (EC), organic matter content (OM), availability P...
Twenty isolates of bacteria were successfully isolated from rhizosphere soil samples collected from different plant species growing at various locations in North Jeddah, Saudi Arabia to investigate their effects on Cucumis sativus L. cv. Marketmore growth and damping-off disease caused by Pythium aphanidermatum. The results of dual culture method showed that only three isolates out of twenty, w...
Rhizobacteria play a positive role as biocontrol agents well Plant Growth Promoting (PGPR) agents. The research objective was to obtain indigenous rhizobacteria isolates on cocoa plants that have the potential inhibit attack of P. palmivora fungal pathogens, and act PGPR in vitro vivo. results study concluded TRI 7/1, 8/8, GM 7/9 7/10 had highest ability growth pathogen. lowest disease severity...
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 proces...
Seed inoculation with plant growth promoting rhizobacteria (PGPR) is an ideal tool to supply the soil with a high density of beneficial microorganisms. However, maintaining viable microorganisms is a major problem during seed treatment and storage. In this work, an evaluation was made of the effect of bacterial immobilization in nanofibers on the stability (viability and maintenance of benefici...
