| Abstract: | The possible interaction of herbicides Bromoxynil and Afalon S with Azospirillumspp. and growth of maize was investigated in a greenhouse experiment. Neither inoculation nor herbicide application with or without inoculation had significant effect on the major groups of soil microflora (bacteria, actinomycetes, and fungi). The highest values of nitrogenase as well as dehydrogenase activity were recorded in treatment received only Azospirillum. Incorporation in soil of either Bromoxynil or Afalon S at the recommended field dose seemed to have no significant effect on the enzymatic activities, while application of these herbicides with Azospirillum had stimulatory effects in some cases. The application of either Bromoxynil or Afalon S significantly increased the dry weight of roots and shoots at 45 days period. The effect of herbicide on plant growth was more pronounced when applied with Azospirillum and the highest stimulatory effect was observed when Afalon S was applied with the N2-fixing microorganism. |
