Book Description
"The purpose of the Iowa Corn Yield Test is to provide impartial comparable performance records on a relatively large number of hybrid combinations. This bulletin presents information about each hybrid tested for yield, stand, moisture, root and stalk lodging, ear height, and dropped ears. The relative agronomic value of the yield, dry matter content of grain, lodging resistance and ears on stalk. The information present ed should be of value to both the purchaser and the producer of hybrid corn seed, since it gives a reliable estimate of the relative performance of various hybrids when grown in different areas of Iowa."--Page [753].

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]

Book Description
"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
"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
"The Iowa Corn Yield test has been conducted annually since 1920. The main purpose of this test is to provide information that will help Iowa farmers select seed of hybrids best adapted for the area in which they live. This bulletin reports the performance of hybrids tested in 1957. Also shown are comparisons of hybrids tested for 2-year, 3-year and 4-year periods." -- p. 3
