2002 Hybrid Corn Performance Data Available

November 22nd, 2002

AMES, Iowa - Results of the 2002 Iowa Crop Performance Test for hybrid corn are now available on the Internet at the Iowa Crop Improvement Association (ICIA) website: http://www.agron.iastate.edu/icia/. These reports include performance information on yield, moisture, root lodging, stalk lodging, dropped ears, stand and percent of protein, oil and starch.

During 2002, researchers evaluated 520 hybrids from 61 seed companies and from Iowa State University. Each entry was tested in one or more of seven districts throughout the state with three testing locations in each district. The state's 2002 average corn yield in these tests was 179 bushels per acre.

District yield averages were:
District 1: 172 bushels per acre
District 2: 177 bushels per acre
District 3: 188 bushels per acre
District 4: 184 bushels per acre
District 5: 191 bushels per acre
District 6: 178 bushels per acre
District 7: 164 bushels per acre

Sixteen new tables have been added to the 2002 test report because of the increasing number of new hybrids being released every year. These data include performance results at several locations during one year in addition to the three locations included in each district report. The data are averaged across districts to help predict which hybrids may have the best relative performance potential during next year's growing conditions.

DTN (Data Transmission Network) will be including a summarized version of the Iowa Crop Performance Test for corn on its computer system.

Iowa Crop Improvement Association (ICIA) conducts the Iowa Crop Performance Tests in cooperation with the Iowa Agriculture and Home Economics Experiment Station at ISU and ISU Extension. The program offers unbiased, third party, on-farm information to Iowa growers on commercial seed.

ICIA provides performance information on hybrids and varieties for alfalfa, barley, corn, oat, soybean, triticale and wheat.
