Abstract
The present study was planned to determine the herbicide tolerance Rhizobium species were selected from three different leguminous plants namely Arachis hypogaea L, Vigna mungo L., and Vigna radiate L. Herbicides such as Atrazine, Paraquat Dichloride and Pendimethalin were used for this purpose in the concentrations such as .0.1, 0.2, 0.3%. Rhizobium species are designated R1, R2 and R3 viz, Groundnut, Black gram and Green gram. R1 isolates from groundnut leguminous plants were showed that better performance on Pendimethalin than compared to Atrazine and Paraquat Dichloride. Pendimethalinwas showed zone of inhibition at 0.1% level. The efficient improved Rhizobium isolates from groundnut are subjected to again herbicide tolerance, and the results are same like that, when the herbicides concentrations was increased maximum zone of inhibition was noticed. Overall results are highlighted that R1 (Arachis hypgaea L.,) isolates had a adverse effect on the Pendimethalin at 0.3 % level was safer to Rhizobia.. If Rhizobial strains show sensitivity to herbicides, herbicide-resistant strains need to be developed. Further study was extended to test effect herbicides under field conditions on the growth of Rhizobia.
Keywords: Rhizobium, Herbicide, Leguminous plants and strain improvement.
