2004 Small Grain Performance Data Available
AMES, Iowa -- Results of the 2004 Iowa Crop Performance Test for winter and spring small grains now are available online at http://www.agron.iastate.edu/icia/. Published bulletins can be requested by contacting Iowa Crop Improvement Association (ICIA) at (515) 294-6921 or the Iowa State University (ISU) Extension Distribution Center at (515) 294-5247.
The winter test included wheat and triticale. The wheat test analyzed 14 hard red winter, five soft red winter and two hard white winter varieties planted at Ames, Crawfordsville and Lewis. Average variety yields were 65 bushels per acre.
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 11 named triticale varieties and two winter wheat checks planted at Ames, Sutherland and Crawfordsville. The triticale performance was down relative to previous years, though the best triticale still performed better than the winter wheat. Average variety yields were 42 bushels per acre for wheat and 46 bushels per acre for triticale. The top triticale variety averaged 52 bushels per acre. The performance data reported includes grain yield, test weight, heading date, plant height, percent lodging and winter survival.
The spring test included barley and oat. The barley test evaluated 16 named varieties conducted at Ames, Sutherland and Nashua. Average yields and test weights were 76 bushels per acre and 48 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 141 bushels per acre and 34 pounds per bushel. Performance data includes grain yield, test weight, heading date, plant height, groat percentage, lodging and disease reactions.
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.
