An irrigation efficiency model for optimum irrigation management

Creator:: Isbell, Brett, 1978-
Abstract:: Improved water use efficiencies in irrigated agriculture are necessary to assist in coping with the accelerating demand and economic competition for the world's fresh water supply and increasing ecological concerns. This will likely rely in part on optimum irrigation, which implies regulated deficit irrigation. While conventional irrigation management is intended...

Evaluation of models for estimating surface irrigation infiltration parameters : Data protocols and algorithm performance

Creator:: Isbell, Sarah A.
Abstract:: Often furrow irrigation application efficiencies are low compared to sprinkler systems. The primary goal of furrow irrigation is to infiltrate a relatively uniform target depth of water necessary for the crop, while minimizing the amount of runoff. The concept is difficult because water can infiltrate differently at all locations in...

Spring irrigation management of perennial ryegrass (Lolium perenne L.) seed production

Creator:: King, Craig Millhouser
Abstract:: Introduction of later maturing cultivars of perennial ryegrass (Lolium perenne L.) places more seed production fields in a period of drought common to Oregon during vital stages of reproductive development. During these stages, the final yield of the crop is largely determined by the number of seeds set, and the...

The response of winter wheat to irrigation in the Willamette Valley

Creator:: Rossner, John Theodore
Abstract:: Some consideration has been given to the irrigation of winter wheat in the Willamette Valley of Oregon. This important crop has yielded quite well since the development and introduction of the stiff-strawed, semi-dwarf wheats, but, because of the usually dry early summers, it has been suggested that irrigation of winter...

Evaluation of the ownership, leasing, and residency restrictions of proposed amendments to the reclamation laws : three federal irrigation districts in Oregon

Creator:: Spies, Paul Andrew
Abstract:: The Reclamation Act of 1902, as amended, is the basic legislation governing the distribution of water from federal projects for irrigation purposes. In the three-quarters of a century since the passage of this Act, technological, economic, and legal developments have forced a reappraisal of the original intent of the Reclamation...

Spring irrigation management of tall fescue (Festuca arundinacea Schreb.) seed crops

Creator:: Orthel, Krista D.
Abstract:: Later maturing cultivars and increased ability to apply irrigation have led to inquiries by producers about proper irrigation management in tall fescue (Festuca arundinacea Schreb.) seed crops. The literature reveals little information about irrigation of perennial grass seed crops in general, and none about tall fescue in particular. Willamette Valley...

Characterizing hydraulics and water distribution of furrow irrigation in northeast Malheur County

Creator:: Mittelstadt, Robert
Abstract:: Furrow irrigation is the dominant practice for irrigating row crops in the western Treasure Valley region near Ontario, Oregon. Though improvements have been made in management practices over the years, excessive runoff and deep percolation are still important problems contributing to surface water and groundwater degradation. Field observations were made...
