Abstract: Rhizobium is the most well known species of a group of bacteria that acts as the most effective symbiotic fixer of nitrogen. Effectiveness of native Rhizobium on different genotypes of Soybean was studied with 10 advanced genotypes i.e. RSC 11-02, RSC 11-03, RSC 11-04, RSC 11-05, RSC 11-06, RSC 10-52, RSC 10-71, RSC 11-08, RSC 11-09, RSC 11-10. Data from field study revealed that highest plant height (120cm/plant) was associated with soybean variety RSC 11-06(T5). Highest fresh weight (209.33 g/plant) and dry weight (52.5 g/plant) of shoot were associated with soybean variety RSC 11-10 (T10). Furthermore, total the N uptake (712.38 mg/plant) observed was highest on soybean variety RSC 11-02 (T1). Highest no. of pods/plant (100.66) was observed in soybean variety RSC 11-10 (T10) and highest grain yield (33.02 q/ha.) was associated with soybean variety RSC 11-02 (T1). The poorest performance was observed in case of RSC 11-08 (T8) in overall findings while the better performance of RSC 11-02 (T1) on the basis of its effective symbiosis with native Rhizobium followed by RSC 11-10 (T10).Ten Rhizobium isolates from effective root nodule of each variety of soybean were isolated. These rhizobia isolates were also tested for their effectiveness in JS-9305 variety of soybean under glass house condition. Data from Glass house experiment revealed that, the highest plant height (145 cm/plant) was associated with isolate present in (T2) i.e. Rhizobium isolated from RSC 11-03 variety. Highest fresh weight of shoot (11.17 g/plant) and dry weight (2.92 g/plant) were associated with (T1) i.e. Rhizobium isolated from RSC 11-02. Further average no. of nodule/plant (14.33%) was observed highest in (T9) rhizobium isolated from RSC 11-09. Glasshouse experiment showed that none of the isolates obtained from different genotypes of soybean is not effective in JS-9305, as the nodulation in JS 9305 is very poor.
