  • 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...

  • Water relations in red and white clover seed crops

    Creator:
    Oliva, Ruben N.
    Abstract:
    Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...
