Results of the 2002 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 will
be available in
November and can be requested by contacting Iowa Crop
Improvement Association at 515-294-6921.
The winter test included wheat and triticale. Triticale is a
grain derived from crossing wheat with rye. It is grown
primarily for animal feed as either a grain or forage crop.
The wheat test analyzed 13 hard red winter, six soft red winter
and two hard white winter varieties, plus four experimental
lines planted at Ames, Crawfordsville and Lewis. The winter
triticale test studied 11 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 83 bushels per
acre for wheat and 87 bushels per acre for triticale. The top
experimental triticale lines averaged 107 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 and oat. The barley test
evaluated 16 named varieties conducted at Ames, Calumet and
Nashua. Average yields were 89 bushels pre acre and test weights
were 49 pounds per bushel.
The oat test included 32 named varieties and eight experimental
lines planted at Ames, Calumet, Crawfordsville, Lewis and
Nashua. Average yields were 121 bushels per acre and test
weights were 33 pounds per bushel. Performance data for the
barley and oat test includes grain and straw yield, test weight,
heading date, plant height, groat percentage, lodging and
disease reactions.
The small grain performance is coordinated by the
Iowa Crop
Improvement Association (ICIA), headquartered in Iowa State
University's 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.
