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]

Download or read book The 1944 Iowa Corn Yield Test written by Francis Reiss and published by . This book was released on 1945 with total page 56 pages. Available in PDF, EPUB and Kindle. 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]
