A cause of economic reasons the cotton surface decreases and cotton planting trend to after autumn productions. To reduce time and cost of production, cotton cultivation without tillage was recommended. However, in this method management of diseases was important. Verticillium wilt caused by Verticillium dahliae, was one of the most important factors limiting crop cultivars and susceptible to the disease. This study carried out to investigate the effect of no tillage method on cotton Verticillium wilt in randomized complete block design with four replications and natural infection of the pathogen (Verticillium dahliae) in three years. The main plot was tillage (moldboard plow瘫, chisel瘫, disk and no tillage) and three cotton cultivars contain Shirpan, Armaghan and T3 considered as a sub plot. The results show that applying different tillage methods did not have significant effect on the index Verticillium wilt. With respect to the results, in no tillage system after wheat harvesting could applied T3 cultivar whose relatively earliness and more tolerant to Verticillium wilt with good performance.
