Oregon crop water use and irrigation requirements

Creator:: Oregon State University. Extension Service and Cuenca, Richard H., 1947-
Abstract:: Provides consumptive use and net irrigation requirements for economically important crops in 27 climatic regions in Oregon. Computations are based on the modified Blaney-Criddle calculation method and climatic database information. Contains tables of: 1) The typical growing seasons of selected Oregon crops by region and 2) Crop water (ETcrop) and...

Estimating crop yield and production changes as a function of irrigation deficit based on watershed and county level data

Creator:: Darakjian, Priscila
Abstract:: Response of agricultural crops to irrigation water deficit is well-understood at the field scale. Broader scale (watershed and county levels) studies have been less frequently performed. Data collection at the field level for extensive areas is time consuming and expensive. The importance of studies at a broader scale for evaluating...

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...
