In order to investigation on effect of different tillage methods on Wheat yield and soil physical and chemical properties in wheat - fallow rotation, This experiment is conducting by Randomized Completed Block Design with 4 replications and 5 treatments in Station of Ghamloo (Kurdistan) in 2 phases for 3 years since 2004. The tillage treatments were: Chisel plow in fall +sweep in spring (A1); Non moldboard plow + sweep in spring (A2); No tillage in fall + Herbicide in spring (A3); No tillage in fall + sweep in spring (A4); Check (Moldboard plow in spring) (A5). In all of treatments, variety of Azar 2 with grain drill was planted equally. The results of combined variance analysis revealed that the wheat yield and components in different years were different in order to difference in rate and distribution of precipitation and cold rate of weather in different years. The product yield in the first year (1963 kg ha-1) was the highest. Effect of tillage treatments on wheat quantity and quality and also yield components was significant, So that, the highest amounts of almost measured factors, obtained from treatment (A3).
