In the previous half-century, natural rock phosphates (PN) have been a valuable alternative for phosphorus (P) fertilizer sustainable agriculture; furthermore, phosphogypsum (PG) has widely used as soil amendment since it improves some properties, increases crop yields, and represents an environmental concern that can make good economic profit; this research aimed to study effects of microbial ...

Gerbera jamesoniiis of commercial significance and fifth most used cut flower in the world today. A pot experiment was performed to see the effect of co-inoculation of arbuscular mycorrhizal fungi (AMF) i.e. (Glomus mosseae andAcaulospora laevis) with phosphate solubilizing bacteria Pseudomonas fluorescensin the presence of different doses of superphosphate (low, medium, high) on growth establi...

Mangrove seedlings were treated with a mixture of two bacterial species, the slow-growing, N(2)-fixing bacterium Phyllobacterium sp. and the fast-growing, phosphate-solubilizing bacterium Bacillus licheniformis, both isolated from the rhizosphere from black, white, and red mangroves of a semiarid zone. Nitrogen fixation and phosphate solubilization increased when the mixture was used compared t...

The application of biofertilizers constitutes one of the main components of nutrient management with a fundamental role in sustainable agriculture and the improvement of plant qualitative traits. The present research assessed the effect of various treatments of phosphate solubilizing bacteria including Pantoea agglomerans strain P5 and Pseudomonas putida</...

inoculation of phosphate-solubilizing microorganisms along with rock phosphate is known to enhance the available p from soil. the success of such solubilization is largely dependent on the ability of the inoculant strain to survive under adverse environmental conditions. in this context, liquid inoculants are gaining importance and are becoming popular with longer shelf-life. in the present inv...

in order to evaluate the efficiency of plant growth promoting rhizobacteria (pgpr) plus nitrogen and phosphorous chemical fertilizers on relative agronomic efficiency of p and n fertilizers and some agronomic parameters of wheat (triticum aestivum l.) cultivar n-80-19, an experiment was conducted at sari agricultural sciences and natural resources university during growing season of 2008-2009. ...

Biofertilizers have been used as sources to improve plant nutrients in sustainable agriculture. Experiments were conducted to evaluate the potential of phosphate solubilizing bacteria (PSB) Bacillus megaterium var. phosphaticum and potassium solubilizing bacteria (KSB) Bacillus mucilaginosus inoculated in nutrient limited soil planted with pepper and cucumber. Results showed that rock P and K a...

The transformation of phosphorus (P) is a major factor of lake eutrophication, and phosphate releasing bacteria play an important role in the release process. Experiments were conducted to investigate P content and characterize phosphate solubilizing bacterial composition at the molecular level in a shallow eutrophic lake and a wetland. Results showed that P concentrations were relatively high ...

in order to study the effect of synorhizobium meliloti on growth and nutrients uptake of sesame, a greenhouse test was carried out. the first isolates investigated in iaa and siderophore producing and their ability in solubilizing inorganic phosphates. the results showed that all of isolates were able to produce auxin with different among. the maximum amount of iaa production was 59.5 g ml-1 th...
