Identification of effective PGPR(s) for management of herbicidal stress towards successful cultivation of Soybean (Glycine max L. Merrill)

To assess the compatibility of different herbicides recommended for soybean with plant growth promoting rhizobacteria (PGPR) including the native strain of Rhizobium so that the tolerant microbes could be used as a potential herbicide tolerant microbial culture to support the soybean crop nutritionally on the growth performance of the soybean ( Glycine Max L. Merrill) crop. The study was carried out in the Department of Agricultural Microbiology, College of Agriculture, IGKV, Raipur, Chhattisarh, India during 2021-2022. In this study the soybean crop was inoculted by cultures of Bradyrhizobium daqingense , Paenibacillus polymyxa and Bradyrhizobium japonicum . As recommended herbicides for soybean pre emergence herbicides diclosulam and pendimethalin were sprayed to the soybean plant @ 52ppm/ha and @ 6ppm/ha, respectively at 5 days after sowing. Post emergence herbicides propaquizafop and imazethapyre were sprayed to the soybean plant @ 1.2ppm/ha and @ 2ppm/ha, respectively and their cocktail mix of propaquizafop and imazethapyre were sprayed to the soybean plant @ 4ppm/ha, at 18 days after sowing. Results from the investigation revealed that pendimethalin was comparatively more compitable with PGPRs than diclosulam under pre emergence herbicide category. In case of post emergence herbicides propaquizafop was comparatively more compitable with PGPRs, than imzethapyre & cocktail mix of propaquizafop + imazethapyre.
