N2  - A four-year study was conducted at two historically wheat-fallow locations in Oregon to compare yields of annually cropped wheat in no-till, disk, and chisel tillage systems with yields of wheat following conventionally chiseled and rodweeded fallow. Tillage method did not affect yields of annually cropped wheat. A management strategy that reduces soil erosion risk and increases average annual production was developed. Annually cropped wheat, including two crops of lower yielding spring wheat, yielded 60% and 70% of winter wheat after fallow at the two locations. On a land use basis, annually cropped wheat, including the spring wheat crops, produced
