Book Description
"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 Description
"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]

"This bulletin is the annual report of the Iowa Corn Yield Test. This test is conducted by the Iowa Corn and Small Grain Growers' Association in cooperation with the Iowa Agricultural Experiment Station. The purpose is to compare the performance of many hybrids being offered for sale to farmers. We hope that information in this bulletin will help you to choose the best hybrids for planting in 1949." -- p. [233]

Book Description
"This bulletin reports the results of the 1950 Iowa Corn Yield test to compare the performance of many hybrid corn varieties. 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 Description
This history of the scientific and commercial lines of plant development in the United States traces the transformation of the seed from a public good produced and reproduced by farmers into a commodity controlled by businesses and corporations divorced from the uses of their product.
