The important abiotic factor for the plants is soil. It which includes various nutrients and microorganisms for well adapting of plant to environment. The soil near to the face of a root of plant is called rhizosphere Rhizosphere is a vital region of plant ecosystem. which includes various nutrients and micro organisms for well adapting of plant to environment. This study is aimed at assessing rhizospheric nutrient content cultural bacterial fungi.and actinomycetes density in the rhizosphere of Cassia sericea and, which grow profusely in nutritionally-poor soils and environmentally-stress conditions as weed on road side , waste land and agricultural land. The rhizospheric soil of both the weeds are slightly alkaline. Both of the soil have rich organic content. Electric conductivity is more in .Nitrogen, Potassium, Zinc, Sulphur ,are more in Cassia sericea..Hence C. sericea is more dominant than in Parthenium hysterophorus . Phosphorus and Iron content is more in Parthenium hysterophorus. In microbial analysis . C. sericea have much more bacterial colony and actinomycetes than Parthenium hysterophorus. But fungi are more in Parthenium hysterophorus.so both weed plants have comparatively rich in rhizosperic soil nutrition content and microbial density than normal soil this may the one of the reason for their wide spread growth.
