"Successful pork production depends first upon selection of good breeding stock. The breeding stock selected should have the inherent ability to produce and nurse large litter that will use feed efficiently. Equally important are proper feeding and management of the brood sow and her litter." p. [415]

"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]

"This bulletin reports the results of the 1952 Iowa Corn Yield Test in which the performance of 219 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. 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 farm where the hybrids were compared. Any producer of hybrid corn seed was eligible to enter his corn in the test. The widely grown hybrids in each section also were entered by the Iowa Crop Improvement Association. In the back of the bulletin you will find an index listing hybrids tested in 1952. The index also indicates whether the hybrid is a single, three-way, double or multiple cross." -- p. [858]

"Each year the Iowa Farmer has a multitude of corn hybrids from which he can choose seed for planting. Some are well established strains of proven worth while others are new and relatively untried. It is impossible to determine, from the appearance of the seed in the bag, the desirability of any particular hybrid. The real test of its value is determined by planting it along with other hybrids to check its field performance. The Iowa Corn Yield test attempts to provide comparable performance records on a number of hybrids. It is believed that the information presented in this bulletin should afford a reliable comparison of the relative performance of various hybrids when grown in different parts of the state. Data are presented on each entry for yield, stand moisture, root and stalk lodging, ear height, dropped ears and damaged corn. A performance score has been used in evaluating the relative agronomic value of the various hybrids tested." -- p. [473]

"A windbreak, as we generally think of it in Iowa, is a narrow belt of trees planted to give the farmstead protection against winter winds. Much of Iowa's land is relatively level to gently rolling. there is little native timber except along rivers and streams. This combination permits northwesterly winter winds to make a clean sweep across th eland. Something is needed to break their force." -- p. [921]
