2003 Small Grain Performance Data Available
AMES, Iowa - Results of the 2003 Iowa Crop Performance Test for winter and
spring small grains now are available on the Internet. The Web site is http://www.agron.iastate.edu/icia/.
Published bulletins can be requested by contacting Iowa Crop Improvement Association
at (515) 294-6921.
The winter test included wheat and triticale. The wheat test analyzed 16 hard
red winter, six soft red winter and two hard white winter varieties, plus four
experimental lines planted at Ames, Crawfordsville and Lewis.
Triticale is a grain derived from crossing wheat with rye and is grown primarily for animal feed as either a grain or forage crop. The winter triticale test studied 19 named varieties and 25 experimental lines planted at Ames, Calumet, Crawfordsville, Lewis and Nashua. The triticale performed well and had slightly higher yields than the wheat trials. Average variety yields were 84 bushels per acre for wheat and 89 bushels per acre for triticale. The top experimental triticale lines averaged 106 bushels per acre. The performance data reported includes grain and straw yield, test weight, heading date, plant height and winter survival.
The spring test included barley, oat and spring triticale. The barley test evaluated 16 named varieties conducted at Ames, Calumet and Nashua. Average yields and test weights were 87 bushels per acre and 50 pounds per bushel. The oat test included 28 named varieties and 12 experimental lines planted at Ames, Calumet, Crawfordsville, Lewis and Nashua. Average yields and test weights were 121 bushels per acre and 34 pounds per bushel. The triticale test included 19 named triticale varieties and two spring wheat checks planted at Lewis, Ames, and Nashua. Average yields and test weights were 68 bushels per acre and 54 lbs per bushel. Performance data includes grain and straw yield, test weight, heading date, plant height, groat percentage, lodging and disease reactions.
The small grain performance tests are coordinated by the Iowa Crop Improvement Association (ICIA), headquartered in Iowa State University's (ISU) Department of Agronomy. The ICIA's crop performance testing program is a cooperative effort with the Iowa Agriculture and Home Economics Experiment Station at ISU and ISU Extension. The program offers unbiased, third-party information to Iowa growers on commercial seed they can purchase. Information on the adaptation and performance of hybrids and varieties is offered for alfalfa, barley, corn, oat, soybean, triticale and wheat.
