Iowa State University (ISU)
Extension publication 2007 Iowa Crop Performance Tests --
Alfalfa and Other Forages (AG 84) will be available Oct. 29, and
may be requested by contacting Iowa Crop Improvement Association

Center at

The 2007 alfalfa tests include entries of commercial varieties
conducted at Ames and Nashua. Potato leafhopper tolerance trials
were conducted at Ames. Performance data provided with the
results include yield in tons per acre, fall dormancy ratings
and disease resistances.
No winterkill occurred during the 2006-2007 winter. A late cold
weather event in April, with temperatures down to 20 degrees F,
greatly reduced yields of all cuttings. Yields ranged from 3.34
to 5.16 at Ames and 4.07 to 6.76 at Nashua. All yields are
expressed in tons per acre on a dry matter basis. Results from
orchardgrass, perennial ryegrass, reed canarygrass and timothy
grass tests are included as well.
ICIA's crop performance testing program is a cooperative effort
with the Iowa Agriculture and Home Economics Experiment Station
and ISU Extension. The program offers unbiased, third-party
information to Iowa growers on commercial seed available for
them to grow. Information on the adaptation and performance of
hybrids and varieties is currently offered for alfalfa, barley,
corn, oat, soybean and wheat. |
