Fallow water retention and wheat growth as affected by tillage method and surface soil compaction

Creator:

Schillinger, William F.

Abstract:

No-tillage winter wheat (Triticum aestivum L.) grown in a wheat-fallow cropping system has consistently produced lower grain yields than conventionally tilled soils in the semiarid Pacific Northwest. A 2-year study was conducted in a long-term tillage trial at Moro, OR to determine factors responsible for differences in wheat growth and...

Fallow water retention and wheat growth as affected by
Effect of nitrogen and water stresses during tillering and grain- filling in wheat

Creator:

Ashraf, Muhammad, 1952-

Abstract:

The CERES-Wheat Crop Growth and Development model treats temperature, nitrogen and water stresses as limiting factors. For each day the model calculates a stress index for temperature, N and water, compares the magnitude of the indices, and then adjusts the calculated daily potential growth using the index of the most...
