The aims of the experiment were to evaluate the effect of rock phosphate application and combination betweenphosphate-solubilizing bacteria with farm yard manure on nutrient uptake and yield of soybean. Factorial experiment design with two factors was used in randomized complzte block design with three replications. The first factors was level of rockphosphate i.e. : 0; 30; 60; 90 kg P ha· I, and the second factor was combination of phosphate solubili=ing bacteria andfarm yard manure: without phosphate solubi/i=ing bacteria andfarm yard manure; phosphate solubilbing bacteria (Pseudomonas fluorescens); farm yard manure 10 ton ha"I, and phosphate solubilizing bacteria + farm yard manure. The results indicated that rock phosphate and combination of phosphate solubilizing bacteria andfarm yard manure application increased nutrient (N, p, K) uptake and grain yield of soybean. Optimum dosage of rock phosphate in soil without phosphate-solubilizing bacteria andfarm yard manure (control) was 72.15 kg P hdl which gave maximum yield of soybean was 7.73 g pori. While with phosphate-solubilizing bacteria. farm yard manure and phosphate solubilizing bacteria+farm yard manure obtained optimum dosage of rock phosphate were 62.26, 63.94, and 62. 21 kg P hd1 , respectively, which gave maximum yield of soybean were 8.17, 7.95, and 8.43 g pori, respectively.

Phosphate Solubilizing

Plants are often challenged by multiple abiotic stresses simultaneously. The inoculation of beneficial bacteria is known to enhance plant growth under these stresses, such as phosphorus starvation or salt stress. Here, for the first time, we assessed the efficiency of selected beneficial bacterial strains in improving tomato plant growth to better cope with double stresses in salty and P-deficient soil conditions. Six strains of Arthrobacter and Bacillus with different reservoirs of plant growth-promoting traits were tested in vitro for their abilities to tolerate 2–16% (w/v) NaCl concentrations, and shown to retain their motility and phosphate-solubilizing capacity under salt stress conditions. Whether these selected bacteria promote tomato plant growth under combined P and salt stresses was investigated in greenhouse experiments. Bacterial isolates from Cameroonian soils mobilized P from different phosphate sources in shaking culture under both non-saline and saline conditions. They also enhanced plant growth in P-deficient and salt-affected soils by 47–115%, and their PGP effect was even increased in higher salt stress conditions. The results provide valuable information for prospective production of effective bio-fertilizers based on the combined application of local rock phosphate and halotolerant phosphate-solubilizing bacteria. This constitutes a promising strategy to improve plant growth in P-deficient and salt-affected soils.

And Oxidative Stress

Phosphate-solubilizing bacteria (PSBs) were isolated from different plant rhizosphere soils of various agroecological regions of India. These isolates showed synthesis of pyrroloquinoline quinone (PQQ), production of gluconic acid, and release of phosphorus from insoluble tricalcium phosphate. The bacterial isolates synthesizing PQQ also showed higher tolerance to ultraviolet C radiation and mitomycin C as compared to Escherichia coli but were less tolerant than Deinococcus radiodurans . Unlike E. coli, PSB isolates showed higher tolerance to DNA damage when grown in the absence of inorganic phosphate. Higher tolerance to ultraviolet C radiation and oxidative stress in these PSBs grown under PQQ synthesis inducible conditions, namely phosphate starvation, might suggest the possible additional role of this redox cofactor in the survival of these isolates under extreme abiotic stress conditions.

Phosphate Solubilizing

Fluorapatite-solubilizing bacteria were isolated from the hyphosphere of the ectomycorrhizal (ECM) fungus Wilcoxina sp., a dominant species in the Picea glauca (Moench) Voss rhizosphere. Hundreds of strains isolated from the ascomycete Wilcoxina sp. could dissolve tricalcium phosphate, while only 27 of them could produce clarification halos on fluorapatite-amended solid medium. Most of the fluorapatite-solubilizing strains belonged to the Burkholderia genus. Scanning electron microscopy observations have shown that these efficient phosphate-solubilizing bacteria (PSB) were able to completely solubilize fluorapatite crystals within 22 h. The efficient PSB Burkholderia sp. strain 205 and Curtobacterium sp. strain 168 were tested for their ability to associate with a genetically distant fungal host while fulfilling their phosphate-solubilizing function. Burkholderia sp. strain 205 successfully associated with the basidiomycete Laccaria bicolor (Maire) P.D.Orton when hydroxyapatite was the only phosphorus source available to the fungus, while there was no bacterial development when Laccaria bicolor could access soluble phosphorus as well. Optical microscopic observation of Laccaria bicolor associated with Burkholderia sp. revealed extensive colonization of fungal hyphae by the bacterium. These results suggest an important role of bacteria – ECM fungi associations in white spruce phosphate nutrition.
