Book excerpt: "The Iowa Corn Yield Test is conducted annually to provide impartial comparable performance records on a relatively large number of hybrid combinations. Each hybrid tested is ranked by a performance score based on held, dry matter content of grain, lodging resistance and the percentage of ears held on the stalks. In view of the present world food need, it is important that farmers plant hybrids adapted to their particular locality. The information presented gives a reliable estimate of the relative performance of a considerable number of hybrids when grown in different areas of Iowa." -- p. [865]

Book excerpt: "The main purpose of the Iowa Corn Yield Test is to compare the performance of corn hybrids and to make the information available to Iowa farmers. In 1954 we tested 90 corn hybrids at each of three locations in the northern section of Iowa. ... One-hundred corn hybrids were compared in each of the other three sections of the state. The hybrids were planted at three locations in each section, but the district 10 field was not harvested because of drouth conditions and a poor stand. They hybrids entered in the 1954 test were planted on about 72 percent of the total Iowa corn acreage, according to results from a survey of farmers. Six characteristics of each hybrid were recorded and summarized. These were yield, stand, moisture content at harvest, root and stalk lodging, and dropped ears. You will find a performance record for each hybrid for these characteristics in the tables of data. An index listing the hybrids tested in 1954 and the name and address of each entrant is given in the back of the bulletin. When the seed was packeted for planted, each entry was given a number. The entries were known only by this number until after the plots were harvested and the calculations completed. Therefore, no person concerned with the test know the identity of any entry. The presentation of these results does not imply approval of these hybrids by the Iowa Crop Improvement Association or the Iowa Agricultural Experiment Station." -- p. [2]
