Results of the Iowa Corn Yield Test are published to aid Iowa farmers in selecting corn hybrids. This is the seventy-fourth consecutive year for the test. Data from these tests are available in three different formats. These data are first released on Iowa State University Extension's computer communication network (EXNET) usually around Thanksgiving. Anyone can subscribe to EXNET at a cost of $25 per year and receive the data as soon as they are released. All that is required is a computer, a modem, and the cost of the telephone call. For additional information about EXNET, contact EXNET, 108 Atanasoff Hall, Iowa State University, Ames, Iowa 50011, telephone number 515/294-8658.
