Examining climate change effects on wheat
Date:2/24/2011

This release is available in Spanish.

Wheat growers in the Southwest have a better idea about how to adjust to climate change in the decades ahead, thanks to U.S. Department of Agriculture (USDA) scientists in Arizona.

Researchers with the USDA's Agricultural Research Service (ARS) installed infrared heaters in experimental wheat fields at the agency's Arid-Land Agricultural Research Center in Maricopa, Ariz., to simulate growing conditions expected by 2050. ARS is USDA's principal intramural scientific research agency, and this research supports the USDA priority of responding to climate change.

Wheat is normally planted in Arizona in mid-winter, harvested in late May and irrigated throughout its growing season. Temperatures can range from below freezing in winter to above 100 degrees Fahrenheit in May. But increasing temperatures can drastically reduce yields and increase the threat of drought, making climate change a major concern.

The scientists planted wheat every six weeks between March of 2007 and May of 2009 and applied heat to six of 15 plantings, warming the crops planted each year in March, December, and September. They measured canopy conditions to ensure daytime temperatures in the heated plots rose by 2.7 degrees Fahrenheit and nighttime temperatures rose by 5 or 6 degrees. The team included Bruce Kimball, a retired ARS soil scientist who was the project leader; ARS plant physiologists Gerard Wall and Jeffrey White; and Michael Ottman, an agronomist with the University of Arizona.

The researchers used infrared (IR) heaters suspended above the plants, using a system known as a Temperature Free-Air Controlled Enhancement (T-FACE) apparatus. Developed by Kimball, T-FACE enables scientists to raise the temperature of experimental crops in open fields. The technology is also used by ARS researchers elsewhere and
