Abstract :
In order to evaluation of the effect of tillagedifferent methods and crop residue management on agromorphologic characteristicof wheat cv. Sardari in dry land condition, a field experiment was conducted asStrip plot based on randomized complete block design with four replication in2012. Factors examined include tillage in four levels: moldboard plow withdisk, chisel, compound tillage and direct seeding as the main plot and theplant residue management in four levels : burning, grazing, complete stubbleand no stubble as the subplot. Theresults showed that, The minimum spike weight was about 0.69 g was obtaineddirect seeding that as compared withmoldboard plow with disk decreased by 25% . The maximum spike weight was about 0.88g that was obtained in the use of chiselthat as compared with moldboard plow with disk increased by 2% . The highestgrain yield equal to 909.81 kg/ha wasrecorded from direct seeding. Using ofdirect 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 plantresidue showed that the highest yieldequal to 990.5 and 946.63 kg/ha and was belonged to direct seeding along with the grazing and direct seeding along with burning.
