Book excerpt: "The Concord grape and grapes of this type and hardiness which are the grapes most widely grown in Iowa, require yearly pruning if the grower wishes to obtain heavy annual yields of large-sized, high quality fruit. The illustration on the cover of this bulletin indicates the development and distribution of the fruit which may be expected on correctly pruned vines." -- p. [227]

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.

Book excerpt: "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]

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]
