Water injection into the seed zone as an aid to emergence of dryland cereals

Creator:

Estes, James Patrick

Abstract:

An adequate stand at the optimum time is an important factor affecting potential yield and soil erosion control. However, obtaining adequate stands of fall planted winter wheat in the dryland areas of the Pacific Northwest is often complicated by marginal seed zone soil moisture. The purpose of this laboratory study...

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...
