Rhizosphere Effect of Microorganisms on Green Gram Cultivated Soil - A Field Study

Abstract

The quantitative comparative analysis of the rhizosphere effect between rhizosphere soil and non-rhizosphere soil of the green gram cultivated soil was done based on R：S ratio (Root-Soil ratio). The results revealed that high rhizosphere effect was seen in the rhizosphere soil of green gram also the quantification studies explored that the rhizosphere effect among the microbes was more in bacteria than in fungi and actinomycetes during the plate count method on various media used. The result of the isolation and enumeration of rhizosphere bacterial culture by selective and decimal dilution method revealed that among the bacterial culture, the quantity of Rhizobiumsp(140x10⁶±2.056CFU/ml) was more followed by Phosphate Solubilizing Bacteria(PSB) (89x10⁶±3.080CFU/ml) and Cellulolytic bacteria (54x10⁶±3.012CFU/ml). The lowest count was observed in the TCBS agar medium).
