Download or read book The 1951 Iowa Corn Yield Test written by Joseph Lee Robinson and published by . This book was released on 1952 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bulletin reports the results of the 1951 Iowa Corn Yield Test in which the performance of 261 different corn hybrids was compared. The state was divided into four sections, each of which was subdivided into three districts. A test field was planted in each district except district 10, where the prolonged wet spring forced us to abandon our planting plans. With the exception of district 10 in the southern section, each hybrid entry was tested in all three districts of a section. The map shows how we divided the state into sections and districts and the approximate location of the farms where the hybrids were compared. Any producer of hybrid corn seed was eligible to enter his corn 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 1951. The index also lists the table numbers where the performance record of each entry is shown and indicates whether the hybrid is a single, three-way, double or multiple cross." -- foreword, p. [758]

The function of the Iowa Corn Yield Test is to help make this task easier." -- p.3

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]
