Soil microorganisms play an important role in the sustainability of soil vitality and productivity. In agricultural production, nutrients needed by plants are converted into useful form for plants by microorganisms. Intensive agricultural activities on agricultural soils are a serious threat to soil microorganisms and threaten the sustainability of agriculture in the long run. Soil treatment practices are known to be effective on soil microbial flora. This study was carried out in vertisol soil in Diyarbakır to investigate the effectiveness of conventional tillage, reduced tillage and direct seeding practices on soil microbial flora in the 2016-2017 winter wheat sowing period. Soil samples were taken from the rhizosphere of the wheat plant during the sowing time and flag leaf phenological period. Dilution technique was applied to the samples to determine live bacteria quantities. As a result of the study, it was determined that different tillage practices have a significant effect on soil bacterial count. It was determined that direct seeding (NT) application was significantly increased the number of soil bacteria compared to conventional tillage (CT) and reduced tillage (RT) treatments (p<0.001).
