2005 Small Grain Performance Data Available

9/28/2005

AMES, Iowa - Results of the 2005 Iowa Crop Performance Test for barley, oat, triticale and winter wheat are now available online at http://www.agron.iastate.edu/icia/. Published bulletins will be available after Oct. 12 and 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 spring test included oats and barley. The oat test evaluated 28 varieties planted at Ames, Crawfordsville, Lewis, Nashua and Sutherland. Average variety yields were very high, reaching 162 bushels per acre with average test weights averaging 34.5 pounds per bushel. The barley test evaluated 15 varieties planted at Ames, Nashua and Sutherland.  Average yields were again very high at 105 bushels per acre with test weights averaging 48.1 pounds per bushel.


The winter test included wheat and triticale. The wheat test analyzed 16 hard red winter, three soft red winter and two hard white winter varieties planted at Ames, Crawfordsville and Lewis. Average variety yields were 74 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 12 named triticale varieties and one winter wheat check planted at Ames, Sutherland and Crawfordsville.

 

The triticale performance was low relative to previous years, though the best triticale still performed far better than the winter wheat check. Average variety yields were 52 bushels per acre for the wheat check and 63 bushels per acre for triticale. The top triticale variety averaged 85 bushels per acre. The performance data reported includes grain yield, test weight, heading date, plant height, percent lodging, and winter survival.

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.
