The Effects of tillage different methods and plant residues management on agro morphologic characteristic of wheat Var Sardari in dry land condition

In order to evaluation of the effect of tillage different methods and crop residue management on agromorphologic characteristic of wheat cv. Sardari in dry land condition, a field experiment was conducted as Strip plot based on randomized complete block design with four replication in 2012. Factors examined include tillage in four levels: moldboard plow with disk, chisel, compound tillage and direct seeding as the main plot and the plant residue management in four levels: burning, grazing, complete stubble and no stubble as the subplot. The results showed that, The minimum spike weight was about 0.69 g was obtained direct seeding that as compared with moldboard plow with disk decreased by 25%. The maximum spike weight was about 0.88 g that was obtained in the use of chisel that as compared with moldboard plow with disk increased by 2%. The highest grain yield equal to 909.81 kg/ha was recorded from direct seeding. Using of direct seeding increased grain yield than the use of moldboard plow with disk, chisel, and compound tillage 12, 17, and 24 percent, respectively. Interaction effects of tillage and plant residue showed that the highest yield equal to 990.5 and 946.63 kg/ha and was belonged to direct seeding along with the grazing and direct seeding along with burning.
