The state was divided into four sections, each of which was subdivided into three districts. A test field was located in each district. Each of the 307 entries tested in 1950 was planted in all three districts of a section. Fields in districts 2 and 3 were not harvested because of poor stands. You will find a map in the bulletin showing the division of the state into sections and districts and approximate location of the farms where the hybrids were compared. Any producer of hybrid corn seed was eligible to make entry in the test. Ten widely grown hybrids in each section also were entered by the Iowa Corn and Small Grain Growers Association. In the back of the bulletin you will find an index listing the hybrids tested in 1950. The index also lists the table numbers where the performance record f each entry is shown and indicates whether the hybrid is a single, three-way, double or multiple cross." -- foreword, p. [690]

Book excerpt: "In 1953 we tested 229 corn hybrids in the Iowa Corn Yield test. Each hybrid was tested at a minimum of three locations. The division of the state into districts and sections is shown on the map. Seven characteristics of each hybrid were recorded and summarized. These included yield, stand, moisture, root and stalk lodging, ear height and dropped ears. Each hybrid was ranked by a performance score based on yield, moisture and resistance to lodging and dropped ears. You will find records in the tables showing how each hybrid performed for the above characteristics. An index listing the hybrids tested in 1953 is given in the back of this bulletin. A majority of the entries in the test were made by commercial hybrid corn companies. The Iowa Crop Improvement Association also entered 10 widely grown hybrids in each section as determined by a survey of farmers. The purpose of the Iowa Corn Yield Test is to determine the performance of hybrids. It is not a contest and should not be confused with the 5-acre Iowa Master Corn Growers Contest." -- Foreword, p.
