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...

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...

Establishment of Kura clover for seed with wheat intercrops

Creator:: Snelling, John P.
Abstract:: Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and...

Exploring mechanisms that drive the development of reversible soil hydrophobicity

Creator:: Woolverton, Priscilla B.
Abstract:: This study focuses on one widespread characteristic of poor soil quality: hydrophobic soil. Previous research has produced conclusive evidence to show that soil hydrophobicity is affected by soil organic matter (SOM) and soil water content (WC). Hydrophobicity that responds to changes in WC is a unique form of surface hydrophobicity...
