Book Description
"The Iowa Corn Yield Test attempts to make available an impartial evaluation of various hybrid combinations in respect to yielding ability, lodging resistance, maturity and other agronomic characteristics. It is believed that the information presented in this bulletin may be of value to both the purchaser and the producer of hybrid corn seed, showing as it does the relative performance of various hybrids in different parts of the state. Data are presented on each entry for yield, stand, moisture, root and stalk lodging, dropped ears, ear height and damaged corn. A performance score has been used as a means of evaluating relative agronomic value of the different hybrids." -- Purpose, p. [853]

Book Description
"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 Description
"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]
