Improving saline-alkali soil and promoting wheat growth by co-applying potassium-solubilizing bacteria and cyanobacteria produced from brewery wastewater

چکیده
Soil salinization is a serious ecological problem. Bacteria and cyanobacteria both have great potential for saline-alkali soil improvement. However, the effect of co-applying bacteria on improvement crop growth promotion in remains unclear. In this study, effects Paenibacillus sabinae (potassium-solubilizing bacteria) Leptolyngbya sp. RBD05 (cyanobacteria), produced brewery wastewater, properties, wheat growth, stress tolerance were studied by applying them to alone or combination. The study indicated that P. important roles increasing N:P ratio, K:Na proline content, superoxide dismutase activity, as well slowing decline nutrient content caused absorption. Compared control group, co-application had best available K dry weight, root length (increased 26%, 85%, 70%, respectively); it was more conducive promoting ratio 41%), which would better improve wheat’s tolerance. This provided new clean strategy quality promote from wastewater treatment.

Experiments were conducted to evaluate the potential of phosphate solubilizing bacteria (PSB) Bacillus megaterium and potassium solubilizing bacteria (KSB) Bacillus mucilaginosus inoculated in nutrient limited soil planted with eggplant. Results showed that rock P and K materials either applied singly or in combination did not significantly enhance soil availability of P and K. PSB increased hi...

Auxin produced by plant growth-promoting bacteria (PGPR) in the wheat rhizosphere, can improve plant yield under water deficit stress condition. To investigate this issue, a completely randomized factorial design with three replications was conducted under greenhouse condition at the University of Maragheh, Eastern-Azarbayjan, Iran during 2019. Treatments were two types of growth-promoting bact...

Saline soils are widely spread in Iran. These intact soils are a great source for the isolation of new bacteria with highly functional metabolites in biotechnology. Actinomycete strains were isolated on starch casein agar and ISP2 with different concentrations of sodium chloride (0, 5 and 10%) from treated soil samples. Pure colonies were cultured on a casein glycerol medium. After complete gro...
