The present study was conducted at Chaudhary Charan Singh Haryana Agricultural University (CCS HAU) Hisar, Haryana in which rhizospheric soil samples of Dalbergia sissoo were collected ten each from field & campus of CCS Haryana Agricultural University, to isolate rhizospheric bacteria. A total of 100 rhizobacterial isolates were isolated from all the collected soil samples. It was observed that 66.66 per cent of the Gram positive isolates were spore formers with terminal or central spore, 80 per cent isolates were IAA producers, 25 per cent were phosphate solubilizers. A total of 14 per cent isolated strains showed antifungal activity exclusively against Fusarium oxysporum, 15 per cent isolates showed against Ganoderma lucidium and 16 per cent of the isolates were found to have both the activities (antagonistic to both Fusarium oxysporum & Ganoderma lucidium). The effect of 18 selected isolates were observed on the plant growth under pot house conditions. Out of the 18 isolates the highest nodule number was reported in the plants inoculated with SD97, shoot length enhancement was maximum observed in the plants inoculated with isolate SD99 & root length enhancement was maximum reported with isolate SD6.
