Research Achievements And Adoption Of No-Till, Dryland Cropping In The Semi-Arid U.S. Great Plains, Neil Hansen, Brett Allen, R. Louis Baumhardt, Drew J. Lyon Jan 2012

Research Achievements And Adoption Of No-Till, Dryland Cropping In The Semi-Arid U.S. Great Plains, Neil Hansen, Brett Allen, R. Louis Baumhardt, Drew J. Lyon

Panhandle Research and Extension Center

The Great Plains region of the United States is an area of widespread dryland crop production, with wheat being the dominant crop. Precipitation in the region ranges from 300 to 500 mm annually, with the majority of precipitation falling during hot summer months. The prevailing cropping system is a two-year rotation of wheat and summer fallow. The adoption of no-till practices has resulted in greater precipitation storage and use efficiency, which has led to greater cropping intensity, higher productivity, more diverse crop rotations, and improvements in soil properties. In Colorado, for example, a no-till rotation of winter wheat–maize–fallow increased total …

Ec94-132 Freeze Injury To Nebraska Wheat, Robert N. Klein, Drew J. Lyon, John E. Watkins Jan 1994

Ec94-132 Freeze Injury To Nebraska Wheat, Robert N. Klein, Drew J. Lyon, John E. Watkins

University of Nebraska-Lincoln Extension: Historical Materials

Nebraska’s adverse weather conditions affect winter wheat during much of its growth. The newer varieties of wheat have increased winter hardiness, and better management practices have reduced winter injury of winter wheat, yet low temperature injury during winter and spring can be destructive. Wheat has little resistance to low temperatures after it begins growing in the spring; therefore, injury from freezes at this time can occur in any part of the state. This publication describes temperature conditions that cause winter injury, symptoms of injury at different spring growth stages, and management practices to use when wheat is injured.
