Nitrogen timing and placement effects on grain and plant nitrogen, and grain yield in hard red winter wheat

Creator:

Bohle, Mylen G.

Abstract:

Hard red winter wheat has the potential to be an alternative crop in the Pacific Northwest, however percent grain nitrogen has been unacceptably low and grain yields have been about only 80% of soft white winter wheat. During the late spring and the summer months there is usually little rainfall,...

The effect of precipitation variation on soil moisture, soil nitrogen, nitrogen response and winter wheat yields in eastern Oregon

Creator:

Glenn, D. M. (David Michael)

Abstract:

The semi-arid regions of the Pacific Northwest are characterized by a high degree of annual temperature and precipitation variation. As a result of this climatic variation, dryland nitrogen fertilizer trials on fallow- ,wheat rotations typically demonstrate a variable response. Wheat growers in the area must not only cope with this...

The effect of fertility level on plant growth and development, water uptake and water stress in dryland wheat production

Creator:

Agamennoni, Raul Jose

Abstract:

Dryland winter wheat in eastern Oregon is usually subjected to water stress several times during the growing period. Moreover, the last three months of growth period depend strongly on the available soil water. The fertility level, stage of growth, availability of soil water and climatic conditions all interact to determine...
