摘要: Experiment was conducted to investigate native Bradyrhizobium and Ensifer sp. isolates for their functional traits in soybean. Soybean rhizobial were tested ability produce indole acetic acid (IAA) both the presence absence of precursor L- tryptophan. A low amount IAA produced by all tryptophan, which ranged from 7.96- 19.26 µg ml-1. In tryptophan (0.01%) found be increased (12.89-30.90 ml-1). Maximum LSER 8 (30.90 ml-1) followed 7 (28.58 The maximum phosphate solubilization (Po4-3) observed with (6.59 mg 100 on 12th day. resistance 66.7% recorded tetracycline (30 disc-1). sensitive more antibiotics than Three (LSBR 3) (LSER 8) SB 271 DS 1 evaluated plant infectivity test effective root nodulation total nitrogen content. use rhizobia as biofertilizer could highly sustainable practice soybean cultivation.
