Abstract
Microbes are found ubiquitous in all environments and rhizosphere and weed rhizosphere is not an exception. In the present approach, rhizospheres of weeds found in Paddy, Sugarcane, Garden, Riverbed and Wasteland soils were screened for enumerating the P-solubilizer population. P-solubilizer population was found high in Paddy and Sugarcane soils and poor in the Riverbed soils. The total available population ranged from 0 to 74×103 /gm dry rhizosphere soils. The study throws light on knowledge of the occurrence of P-solubilizers in the weed rhizosphere environment, evidencing the sustenance of native populations through indirect means in the soil ecosystem during off-season periods and stresses the need for studying the weed rhizosphere microflora in future for better understanding.
