The study proposed to investigate variety, population dynamics of nitrogen obsession and phosphate solubilization bacteria in rhizosphere of sugarcane refined in acrisol and ferrasol soils of Dong Nai province, the Southeast of Vietnam. Nitrogen total, dissolved phosphorus and basic carbon of the soil were determined by utilizing colorimetric method and design described by Walkley-Black. Nitrogen obsession and phosphate solubilization bacteria were isolated on Burk's nitrogen free and NBRIP publishing. Identification, SNPs and nucleotide diversity of picked bacterial strains were based on 16S rDNA sequences accompanying primers 27F and 1492R, SeqScape@Software and Theta (θ) described by Halushka et al.. Validation of nitrogen obsession of strains was carried out by hide presence of nifH accompanying Pol primers. The research found that rhizosphere of sugarcane refined in Dong Nai province were slightly sour, poorly nutrient and had different plant growth advancing bacteria. pH, nitrogen total and organic matter component of the soils were three essential determinants influencing two together populations of nitrogen obsession and phosphate solubilization bacteria in the soils while available planet seen at dawn in the soils was closely accompanying with nitrogen obsession bacteria society rather than phosphate solubilization bacteria populace in the soils. Thirty-one strains unique expressed volume of fixing nitrogen, solubilizing phosphate and biosynthesizing IAA. Fourteen of thirty-one strains were deepened nifH. Twelve of thirty-one strains accompanying high ability of plant growth publicity were identified as species of Bacilli, Acidobacteria, Bacteroides and Betaproteobacteria place Bacilli had the highest Pis and thetas. Bacillus megaterium B6 unique from ferrasols and Sphingomonas sp. P14 isolated from acrisols displayed as potential candidates and were proposed expected tested their skill to promote plant tumor of sugarcane grown in acrisol and ferrasol soils of Dong Nai province.
