The spring test included oats and barley. The oat test evaluated 23 varieties planted at Ames, Crawfordsville, Lewis, Nashua and Sutherland. The test at Crawfordsville was abandoned because of freeze damage that occurred in April. Warm and dry weather in May and June produced yields that varied across the state but were generally lower than the previous year. Test weights were higher than 2006. The statewide average yield for oats was 121 bushels per acre with test weights averaging 34.1 pounds per bushel.

The barley test evaluated 15 varieties planted at Ames, Nashua and Sutherland. Average yields were 63 bushels per acre with test weights averaging 48.9 pounds per bushel.

ICIA's crop performance testing program is a cooperative effort with the Iowa Ag 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 and wheat.
