Abstract:

In this work rhizosphere bacteria’s study present the capacity to increase plant tolerance of grown environment under conditions of added phosphogypsum (PG) (sub-product of phosphoric acid industry). The results obtains were demonstrated that the effects of Bacillus megaterium on the formation of the plant–rhizobium symbiosis of soybean plants depended in the majority of cases on both of the bacterial suspensions presence and PG quantitative ratios. The study shows that the bacterial strains of Bacillus megaterium facilitated an increase of germinated soybean plants. Also the weight and the height increase for all different soils amended with PG.

Keywords:

Bacillus megaterium, phosphogypsum, plant growth-promoting rhizobacteria (PGPR), soybean plant.
