Application of paper mill effluent to sugarcane grown soils increased the populations of Rhizobium and Azotobacter for a particular time and further increase in the duration of irrigation did not significantly contribute to the increase in populations. Prolonged irrigation of the effluent affected the rhizosphere effect (R:S ratio) of these organisms. Populations of Rhizobium and Azotobacter were more in the rhizosphere of sugarcane and increased with the age of the crop in such soils.
