Crop management systems influence plant productivity and nutrient use efficiency, as well as plant growth-promoting rhizobacteria (PGPR), which are known to influence the growth of plants via phytohormone production, phosphate solubilization, nitrogen (N) fixation and antimicrobial activity. The objective of this study was to compare the influence of two crop management system on microbial PGPR...

Plant growth promoting rhizobacteria (PGPR) mediate the soil processes such as decomposition, nutrient mobilization, mineralization, solubilization, nitrogen fixation and growth hormone production. Microorganisms having the phosphate solubilizing capacity can convert the insoluble phosphates into soluble forms through the production of organic acids. Inoculation of seed with P-solubilizing micr...

Rhizobacteria isolated from wild dipterocarp saplings in Central Kalimantan, Indonesia, were subjected to Salkowski's reagent test, which is often used in detecting indolic substances. Among 69 isolates grown in a low-nitrogen medium supplemented with L-tryptophan (TRP), culture fluids of 29 strains were positive to the test, in which 17 bacteria turned red and other 10 pink. All the red type r...

in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...

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...

Abstract Microorganisms that are active and aggressive colonizing the rhizosphere known as rhizobacteria. They able to act biofertilizers, bioprotectants, biostimulants bioremediation. This study aims identify characterize groups of rhizobacteria present in patchouli can produce IAA compounds have ability solubilize phosphate soil. Soil samples were taken from at Purwosari Village, Nagan Raya, ...

In this work, local strains of phosphate-solubilizing microorganisms were isolated and identified from the wheat rhizosphere exogenous acid phosphatase enzymes locally active phosphate- potassium-mobilizing rhizobacteria belonging to genera Escherichia, Rahnella, Bacillus, Enterobacter, Pseudomonas, Pantoea studied. The efficiency physiological properties is determined by production soluble pho...

Chemical based phosphate (PO4-3) fertilizers occupies significant place in agricultural domainand ought to be dangerous (e.g. cause chronic kidney disorders, eutrophication). Hence, world isyelling for an efficient substitute of PO4-3 fertilizer. This fertilizer is being used escalate yieldof green leafy vegetables, which are loaded with health nutrients, consequently, fallingfor this Mediterra...
