. The native population of phosphate solubilizing bacteria (PSB) and total soil bacteria (TB) were enumerated in 132 samples of rhizosphere soil collected from fourteen agricultural areas at Meknes. The results revealed that the bacteria solubilizing rock phosphate are present in all soils analyzed in this study. The number of PSB and TB showed large variations and ranged from 12.5 – 0.002; 150 – 0.52 (x 10<sup>5</sup> CFU/ g soil), respectively within the place of sampling. The correlations between PSB counts and TB (r=0.82), total nitrogen (r=0.66) and organic matter (r=0.83) were positive and significant (p≤0.01). This research extends the knowledge on rock phosphate-solubilizing bacteria population in the rhizosphere of wheat cultivated in the different regions at Meknes.&picture=http://www.aascit.org/aascit/decorators/img/journal/919.jpg)

The aim of present research is to study the relationship between density of rock phosphate-solubilizing bacteria population with physical, chemical and biological properties of the rhizosphere soil of wheat (Triticum aestivum L.). The native population of phosphate solubilizing bacteria (PSB) and total soil bacteria (TB) were enumerated in 132 samples of rhizosphere soil collected from fourteen agricultural areas at Meknes. The results revealed that the bacteria solubilizing rock phosphate are present in all soils analyzed in this study. The number of PSB and TB showed large variations and ranged from 12.5 – 0.002; 150 – 0.52 (x 105 CFU/ g soil), respectively within the place of sampling. The correlations between PSB counts and TB (r=0.82), total nitrogen (r=0.66) and organic matter (r=0.83) were positive and significant (p≤0.01). This research extends the knowledge on rock phosphate-solubilizing bacteria population in the rhizosphere of wheat cultivated in the different regions at Meknes.
