Pre and Post Emergence Application of Imazthapyr on N Uptake, Nodulation and Microbial Population of Chickpea Sown after Rice in Vertisols of C. G.

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

“…The cocktail mix was reduced the rate of BSR at maximum level incase of Bradyrhizobium japonicum (0.98, 1.06, 1.10 and 1.22 mg CO2/h/100g BSR rate at 10, 20, 30 and 50 DAHA, respectively), and minimum in case of Bradyrhizobium daqingense (1.12, 1.18, 1.27 and 1.34 mg CO2/h/100g BSR rate at 10, 20, 30 and 50 DAHA, respectively), It is revealed from the study that the BSR was more affected by imzethapyre compared to propaquizafop. The above observation are in close agreement with Ahmad et al (2018) [1] , who stated that under rice-chickpea cropping sequence application of imazethapyr at different doses significantly reduced the BSR rate soon after their application. The toxic effect of these chemicals was traced upto 10 DAS and there after a gradual increment BSR rate was noticed.…”

“…In this study it was proved that Propaquizafop was comparatively more compitable with PSB, than imzethapyre & cocktail mix of propaquizafop + imazethapyre. Significant decrease in phosphate solubilizing bacteria (Enterobacter asburiae) was reported by Ahmad and Khan (2010) [1] due to quizalafop-pethyl, clodinifop, metribuzin, glyphosate herbicides.…”
