phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...

abstract- to investigate the effects of bio-chemical and organic fertilizers on yield and seeds npk contents of pumpkin (cucurbita pepo var. styriaca), an experiment was conducted at the research farm of kurdistan university in 2009 growing season. treatments were included 1) control, 2) seeds inoculated with free-living n fixing bacteria (nfb), 3) seeds inoculated with phosphate-solubilizing b...

Phosphate solubilizing bacteria (PSB) possessing the ability to solubilize insoluble inorganic phosphates were isolated from rhizosphere soil. Eighty-one potential PSBs thus obtained were quantitatively screened for phosphate solubilization. Of these, four bacteria found to be efficient phosphate solubilizers, were selected for further evaluation, and found that they solubilize tricalcium phosp...

In a greenhouse experiment, the nematicidal effect of some bacterial biofertilizers including the nitrogen fixing bacteria (NFB) Paenibacillus polymyxa (four strains), the phosphate solubilizing bacteria (PSB) Bacillus megaterium (three strains) and the potassium solubilizing bacteria (KSB) B. circulans (three strains) were evaluated individually on tomato plants infested with the root-knot nem...

to evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. in this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

Abstract. Suharjono, Yuliatin E. 2022. Bacteria communities of coffee plant rhizosphere and their potency as growth promoting. Biodiversitas 23: 5822-5834. This study aimed to investigate the soil bacteria evaluate in supporting growth. The was collected from Coffea canephora arabica Malang, East Java. bacterial genomic DNA extracted by FastDNA Spin kit while Illumina platform analyzed total gD...

The present study was conducted to isolate phosphate solubilizing bacteria (PSB) from rhizospheric saline soils of coastal Odisha, India and evaluated their ability. Total four PSB were isolated based on the halo zone formation (solubilizing index 2.63-3.14) PVK agar medium characterized biochemical molecular characteristics as Bacillus subtilis (B1), B. megaterium (B2), Sphingomonas paucimobil...

Plants always interact with microorganisms either negatively or positively during their life cycle. The Phosphate Solubilizing Bacteria (PSB) group is one example that has some beneficial effects on the plant. PSB can transform insoluble soil inorganic phosphates into soluble phosphorous so plants absorb them. This research aimed to test isolate's ability solubilize and use 16S rRNA marker gene...

introduction: the most abundant of agricultural soils in iran, are calcareous. in calcareous soils, phosphorus fertilizers use efficiency is low. the usage of soil microorganisms is one of the effective ways to increment the uptake of phosphorus in calcareous soils. this microorganisms using various mechanisms, including the production of plant hormones or the production of organic and inorgani...

in order to investigate the integration of phosphorus fertilizer different levels and phosphorus solubilizing bacteria p.fluorescens on quantitative and qualitative forage yield of two fall barley cultivars, an experiment carried out at research farm of college of agriculture of university of tehran during 2009-2010. the experiment design consisted of three randomized complete blocks in a facto...
