%X The present research work aims to demonstrate the rehabilitation of a  degraded forest land by afforestation of sissoo plants (Dalbergia sissoo  Roxb.) inoculated with nitrogen fixing bacteria sp. In this study,  effects of the three different Rhizobium isolates from three localities  such as i. Kotre-isolate, ii. Pokhara-isolate and iii. Syangaza-isolate  were assessed both in nursery and in the field. It was noted that the  growth and biomass increment of seedlings in nursery as well as in the  field after rhizobial inoculation were significantly high compared to  control one. Among these 3-isolates, Kotre-isolate was found to be  superior to others. Soil improvement around the root of inoculated  seedlings was remarkable high. Nitrogen content of the soil increased in  the range of 20–40% compared to control (only 10–20%). Kotre-isolate,  in general, caused more soil improvement than the other isolates. The  nutrient content in the green foliage, particularly nitrogen, increased  in the range of 30–50%, compared to control one. The considerable  increase in nutrients content of soil as well as in the foliage  indicates the improvement in the quality of site.
