The performance of Terradisc was evaluated in a field experiment during two years in Khuzestan agricultural research centre with 9 treatments, and also compared with traditional and no-till-drill methods. The experimental field was planted by corn in summer and wheat cultivated after corn in fall. Terradisc treatments were factorial at three forward speed levels of 8, 10, and 12 km/h and three levels of discs cutting angles of zero, 30, and 60 degrees. All treatments were applied in three replications. Two years ANOVA results showed that except year of experiment, tillage method, forward speed and cutting angle had no significant effect on wheat yield and yield components. Mean wheat grain yield of first and second experimental years were 5163 and 2658 kg/ha respectively. Variance analysis of technical parameters showed that effects of forward speed and cutting angle were significant on some of these parameters. The results showed that residue cover increased significantly, as cutting angle reduced. The highest and lowest residue cover was 88.6 and 64.7 percent in 60 and zero degrees of cutting angles respectively. MWD was reduced as forward speed increased. MWD was calculated 31.6 mm and 33.6 mm in forward speeds of 12 and 8 km/h respectively. Forward speed of 12 km/h had minimum fuel consumption (11.8 lit/ha), while maximum fuel consumption (15.5 lit/ha) was belonged to forward speed of 8 km/h. finally, according to obtained results, terradisc was recommended as a acceptable option for applying minimum tillage in corn residue with higher forward speed (as much as possible) and lower cutting angle.
