Two experiments were performed to examine the effects of inoculation of field grown wheat with various Azospirillum strains. In the first experiment the soil was sterilized with methyl bromide to reduce the Azospirillum population and15N labelled fertilizer was added to all treatments. Two strains ofAzospirillum brasilense isolated from surface sterilized wheat roots and theA. brasilense type strain Sp7 all produced similar increases in grain yield and N content. From the15N and acetylene… CONTINUE READING

This suggests that the much greater inoculation response of the original strain was not due to N2 fixation but to an increased nitrate assimilation due to the nitrate reductase activity of the bacteria in the roots .
