“…Herbicide application may also kill species of bacteria, fungi and protozoa resulted into upsetting the balance of pathogens and beneficial organisms and allowing the opportunist, disease causing organisms to become a problem (Kalia and Gupta, 2004) [6] . Application of herbicides can potentially influence microclimate that impairs pod yield in groundnut (Sahoo et al, 2017a) [12] . Microorganisms play very essential role in maintaining soil fertility: cycling nutrients, influencing their availability by improving soil structure; supporting healthy plant growth; degrading organic pollutants.…”

The present set of experiment was carried out in the Central farm, OUAT, Bhubaneswar during Rabi 2014-15 with five treatment such as control(without weeding), Butachlor, Alachlor, Oxyflurofen as preemergence herbicides and weed free (manual weeding) having three replication under RBD design to study the impact of pre-emergence herbicides on microbial populations. The application of herbicides have tremendous on impacts population of bacteria and fungi in the rhizospheric soil and their enzyme activities and cause qualitative and quantitative alterations. At 90 DAHT the population of the bacteria and fungus became at par with the initial population i.e. 0 DAHT. Among the control and weed free, the population of bacteria was found highest whereas, the fungal population was moderate in the weed free as compared to other treatments. Application of pre-emergence herbicide affected the microflora population specially bacterial and fungal population. The bacterial population was found to be highest (9x10 5 cfu/g) in weed free where on fungal population was highest (7x10 3 cfu/g) in control treatment. These three herbicides showed drastic reduction in the bacterial as well as fungal population within seven days after the application. An increasing trend of the bacterial and fungal population was observed after seven days and the trend continue up to 90 DAHT. The study confirmed that the herbicides (Butachlor, Alachlor and Oxyflurophen) altered the microbial populations hence to influence pod yield by affects the different soil enzyme activities.

In this study, strain PSBB1 isolated from rhizosphere was identified as, by 16S rDNA sequence analysis and characterized. Strain PSBB1 tolerated glyphosate up to 3200 μg ml and produced IAA (81.6 μg ml), ACC deaminase (69.3 mg protein h), SA (39.3 μg ml) and 2,3-DHBA (26.6 μg ml), solubilized insoluble P (50.8 μg ml) and secreted 29.4 μg ml exopolysaccharides, which decreased with increasing concentrations of glyphosate. Cell damage following glyphosate application was visible under SEM and CLSM. The phytotoxicity of glyphosate on chickpea was variable but significant. . mitigated toxicity and enhanced the size, dry matter, symbiosis, seed attributes and nutritional contents of chickpea. Further, strain PSBB1 declined the levels of CAT, POD, APX and GPX and MDA contents at 4332 μg kg soil glyphosate. Proline also increased under glyphosate stress but declined in inoculated plants. The ability to tolerate higher concentration of glyphosate, the capacity to secrete plant growth regulators even under herbicide stress and potential to reduce the level of proline and antioxidant enzymes makes as an interesting choice for enhancing chickpea production in soils contaminated even with herbicides.
