Effect of conservative tillage and types of rice on field management and wheat operation to stable agriculture

Considering the existence of rice and wheat rotation on 50 thousand hectares of Khuzestan province and the necessity of efficient use of soil, crop year study period (1389-1388) in the city were examined Shoushtar. This research project as chopped blocks in a randomized complete block with three replications was carried out. The first factor in this plan tillage methods that include: T1) moldboard plow disk light (TOF region), T2) disc-style chisel plow, T3) heavy disk Rotator and T4) in two perpendicular heavy disk load time The second factor consists of rice, including high yielding varieties (LD183) and local varieties (Champa), respectively. Results indicated that tillage method and type of significant effect on the number of green plants per square meter, but no tillage methods significant effect on the capacity of a farm is effective. Also, tillage methods on the number and type of soil bulk density, aggregate mean weight diameter, the translation of the soil, grain yield and harvest index had a significant effect. Finally, treatment 4 (two discs of heavy vertical time) with the performance of 5,140 kg per hectare, appropriate size hunk of dirt, with return to 50 percent soil and time is better than other treatments.
