Abstract: 

Introduction: Weed control is the most important challenge for adoption of conservation tillage systems.
Tillage prepares optimum conditions for growth and development of crops. Conservation tillage compared with conventional tillage has many advantages in terms of improving soil conditions and soil moisture retention.
Nevertheless, during the preparation of seed bed, decreasing of soil disturbance in different conservation tillage methods could be resulted in optimal conditions for growth of various weeds. Although each of the conservation tillage methods affect on weed population dynamics and change weed density and diversity, the effects of tillage systems on weed dynamics and diversity depend upon species, location and environment which is complex and not fully understood.
