Iowa Crop Performance Tests (ICPT) provide direct, unbiased comparisons among a large number of corn hybrids and soybean varieties, in a number of different environments. Data are
online within 48 hours of harvest, giving you an early look at test results. There is no other way to get this type of high quality plot management, statistical
integrity, and timely access to information. Our program is backed by an 80-year history of testing, and the credibility of Iowa Crop Improvement
Association, Iowa State University Extension and Iowa State University.
