The present investigation was carried out to isolate and evaluate the effective strains of Rhizobium from Dalbergia Sisoo seedlings. Studies were conducted under greenhouse condition to assess the compatibility and growth-promoting ability of isolated Rhizobium strains. From isolated strains thirteen strains were screened as Rhizobium out of which strain nos. 382, 386, 388, 392 and 393 performed significantly better in nodulation (54.65 to 51.12/plant), shoot length (34.4 to 31.4 cm/plant) and root length 27.8 to 23.4 cm/plant) over untreated control. Ukewise, dry wt and N content of root, shoot and nodule also increased significantly. The overall results indicated that strain no. 388, 393, 392 and 382 were most effiCient among the isolates.
