LENG and BENJAMIN THE SECOND LARGEST CORN CROP in Illinois' history was harvested in 1955. The estimated total production was about 524 million bushels, second only to the record 564 million bushels harvested in 1948, and well above the 449 million bushels produced in 1954. Despite late summer heat and drouth in some sections of the state, and widespread occurrence of stalk rot and corn borer damage, the average estimated yield of 56 bushels per acre was 6.5 bushels above the 1954 average and about 4.5 bushels higher than the 10-year average. 2 PLAN OF THE TESTS Number of hybrids and their sources. Two hundred fifty- two hybrids were grown on five major test fields. Forty- two com- panies and individuals and the Illinois Agricultural Experiment Station furnished seed for the tests. Eighty-one hybrids were grown at DeKalb. Ninety hybrids were entered in the tests at Galesburg and Urbana. Seventy-two entries were grown at Brownstown and sixty-four hybrids at Carbondale. (For a summary of the tests and results on these fields, see Table 1.) A representative of the Illinois Station or of the Illinois Crop Improvement Association collected seed for planting the test fields directly from the warehouses of the producers entering the respective hybrids. Seed of certain Illinois and other open- pedigreed hybrids was furnished by the Illinois Station. Selection of entries. Each year producers of hybrid seed corn are given an opportunity to nominate hybrids for testing on the various fields. In 1955, for the first time in a number of years, a fee was charged for testing hybrids nominated in this manner. 1 EARL R. LENG, Associate Professor of Agronomy, and BENJAMIN KOEHLER, Professor of Crop Pathology. J Estimates of yields for the state were furnished by the ILLINOIS CO- OPERATIVE CROP REPORTING SERVICE, Illinois State Department of Agriculture cooperating with the U.S. Department of Agriculture. 3 BULLETIN No. 598 [January, Location of 1955 test fields The size of certain individual tests was increased, so that it was not necessary to reject any entries submitted. Certain hybrids were entered in the tests to meet the field- performance requirements for certification. A few Station- produced open-pedigreed hybrids were included at each location, and several promising experimental hybrids were grown at some locations. The performance of additional experimental hybrids in 1955 and preceding years is reported in Illinois Bulletin 597. Table 1.

The test fields are usually medium to high in productivity, and each represents a soil type common to the region where it is located. Each field is selected for uniformity in soil type, productivity, and drainage. Approxi- mate locations of test fields are shown on the map on page 4. Soil characteristics and management are described in Table 2. Table 2.

A 9 X 9 lattice-square field-plot design with 5 replications was used on the DeKalb field. The designs used at Galesburg and Urbana were 9 X 10 rectangular-lattices with 3 replications, while an 8 X 9 rectangular-lattice with 3 replications was used at Brownstown. The field-plot design at Carbondale was a randomized block test with 4 replications. Because of time limitations, the data from the Galesburg, Urbana, and Brownstown tests presented in this bulletin were analyzed by the procedure normally used for randomized block tests, rather than by the full procedure for rectangular lattices. Method of planting. All test fields were planted by hand on land prepared in the normal way for corn. Individual plots con- sisted of 2 rows each 5 hills long. Four kernels were planted to the hill at DeKalb, Galesburg, and Urbana; 3 kernels were planted to the hill at Brownstown and Carbondale. Plots were not thinned. GROWING CONDITIONS The 1955 growing season in Illinois was generally favorable. Excessive soil moisture delayed planting operations in some parts of southern Illinois, and both the northern and southern parts of the state were somewhat deficient in moisture during the latter part of the growing season. The three northern test fields were planted in mid-May in good to excellent seedbeds and made vigorous growth. The DeKalb and Galesburg fields suffered to some extent from a lack of moisture in late July and August but produced excellent yields. Planting of the Brownstown and Carbondale plots was delayed until the first part of June by excessive soil moisture, and seedbeds on these two fields were unduly moist when the corn was planted. Heavy rainfall at both locations shortly after the corn was planted resulted in some loss of stands, and parts of the Brownstown field were replanted on June 20. Later growth and development on the two southern fields were excel- lent. However, late summer rainfall was deficient at Brownstown and especially lacking at Carbondale, and yields were lower than might otherwise have been produced (see rainfall data. Table 2). 1956] ILLINOIS CORN TESTS : 1955 7 Moderate to heavy corn-borer infestation occurred at DeKalb, and moderate infestations were noted at Galesburg and Urbana. However, very little stalk-breaking directly attributable to corn- borer injury was noted on these fields. Ear-dropping, probably resulting to a considerable extent from corn-borer damage, was more prevalent than usual on the three northern test fields. Stalk breakage at Urbana and particularly at Brownstown was exceptionally severe. Most of this breakage occurred in September and early October, probably chiefly as the result of stalk rots. Less than 30 percent of the plants at Brownstown were erect at harvest, and only 60 percent were erect at Urbana. As a result, grain quality was rather poor in many plots on these two fields. Moderate stalk-rot infection occurred in the Carbondale test field, with Diplodia, Gibberella, and Charcoal Rot being noted. Relatively little stalk-breaking, however, occurred on this field. Little stalk-rot injury was noted at either DeKalb or Galesburg, and the percentage of plants lodged in these two fields was low. DISEASE DAMAGE 1 Northern (Helminthosporium) leaf blight occurred very sparsely, and rust likewise was of little importance in 1955. Ear rots also were at a comparatively low ebb, particularly Diplodia. From the standpoint of percent of kernels rotted, Fusarium was the most prevalent, damage being estimated at 0.3 percent; about one-third (32.8 percent) of the ears showed traces or more of the infection. Stewart's disease. Symptoms of Stewart's disease could be found on many plants in any corn field in the southern two- thirds of Illinois and in occasional fields farther north. The effect, however, was mild and loss was estimated at only 0.3 percent. Smut. Damage from smut was high in the northern part of Illinois, making the average for the state a little above average. The loss of yield was estimated at 2 percent. 1 Data on disease prevalence and estimates of losses are based principally on surveys made by G. H. Boewe, Associate Botanist, Illinois State Natural History Survey. 8 BULLETIN No. 598 [January, Stalk rots. Stalk-rot damage, particularly down corn, was among the worst on record. Early in September scattered fields were reported in which stalks had rotted badly near the base and were breaking over; examination usually revealed the presence of Diplodia, Gibberella, and Charcoal Rot. Neighboring fields were usually still in good condition, and the cause for the differ- ence was usually not clear. A little later, many more fields had stalk rot and were lodging, primarily because of Gibberella and Charcoal Rot. Diplodia stalk infection was about average except in north- ern Illinois, where it was worse than usual but did not cause much lodging. Gibberella stalk infection was at an unusually high level throughout the state, about as high as in 1946 and 1951, the highest years on record. Charcoal Rot caused the most damage ever known in Illinois. It was particularly bad in the southern half of the state, but there were some badly infected fields all the way to the northern boundary. Charcoal Rot is aggravated by hot, moderately dry weather. Because that type of weather has been common in a considerable part of Illinois for three consecutive years, the disease has been increasing to unusual importance. It is a soil-borne disease of long standing in Illinois which attacks many crops but appears to do most damage to corn and sorghum. In years with cool summers, it is nearly impossible to find a specimen. Even in years like 1955, the disease may be very destructive in one field but practically absent in a field across the road. Stalk rot sometimes was worse in highly fertile fields than in adjacent fields of lower fertility. This relationship appears to hold more for Gibberella and Diplodia than for Charcoal Rot. Little direct relationship between stalk-rot infection and corn-borer attack was noted. The Charcoal Rot fungus usually entered the stalks below the soil surface, although a few cases of above-ground infections were seen. Most of the Diplodia and Gibberella rot started at nodes on the lower end of the stalk but practically none started beneath the surface of the soil. When infected stalks had been entered also by corn borers, their en- 1956] ILLINOIS CORN TESTS : 1955 9 trance was usually higher on the stalk, and in most stalks there was no connection between the corn-borer channels and the lower end of the stalk where the worst rot occurred. At the Brownstown field in south-central Illinois where stalk-rot dam- age was severe, there had been few corn borers. SEED TREATMENT TESTS The seed used for the 1955 seed- treatment test consisted of a composite of three hybrids, which were obtained processed but untreated from commercial producers. They were: 111. 1091 (WF9XHy2)(M14Xl87-2), 111. 1731A (WF9XC103)(Hy2X Oh7A), and U.S. 13 (WF9X38-ll)(L317XHy). All are adapted hybrids in popular use but unrelated to each other to a consider- able extent. The seed was planted at the rate of 16,000 kernels per acre and as second-year corn in a rotation of corn, corn, oats, and clover. The yields in 1955 were the highest ever obtained in these tests although this test was planted in the same rotation and received the same management as in previous years. Another unusual fact was that the first planting emerged from the soil in the same number of days (six) as the last planting. The middle planting emerged in five days. Yields decreased consistently with delay in planting. The seed treatment gave highly significant increases in all three plantings. There were no significant interactions between treatment and planting date. The average of all three plantings showed some highly significant differences between treatments. Increases in stand resulting from the treatment were greatest in the last planting, but the greatest increases in yield were in the first planting. Evidently the early planting was able to make better use of the additional stand and vigor that resulted from seed treatment. Thiram and Captan compounds from several manufacturers were used, and in some tests the same compounds from different manufacturers appeared to differ significantly. When an insecticide to protect the seed against soil-borne insects was added to Thiram and Captan compounds, no in- 10 BULLETIN No. 598 [January, TABLE 3.

Similar results were obtained in 1954, so the value of using insecticides in this manner appears doubtful. In cold tests, formulations containing dieldrin actually caused lower stands than the same fungicide without the insecti- cide. No harmful effects were noted in these field tests, in which germinating conditions were a little better than average, espe- cially for the early planting, and very much better than in the cold test. MEASURING PERFORMANCE The entries of the 1955 test are listed in the tables in alpha- betical order. It is hoped this arrangement will reduce the emphasis often placed on yield alone. Yield of grain. To determine shelling percentage, all the ears from one replicate of each entry were shelled immediately after harvest. From the well-mixed shelled corn one sample was taken to determine the percentage of moisture at harvest. 1 The total acre-yield was calculated as shelled corn containing 15.5 percent moisture, the upper limit allowable in No. 2 corn. The total yield thus obtained for the DeKalb test was adjusted according to the procedure outlined by Cochran for randomized lattice-square designs. 2 Erect plants. The percentage of erect plants in each plot of each entry on each field was estimated at the time of harvest. Lodging may have been due to rootworm damage, weak or rotted roots, corn-borer damage, stalk rots, or weak stalks. Stalks broken above the ear were not considered lodged. Dropped ears. At harvest time, the number of dropped ears in each plot was recorded in the DeKalb, Galesburg, Urbana, and Car- bondale tests. Ear-dropping may have resulted from European corn- borer damage or from other causes. There were very few dropped ears at Brownstown, and so data on this characteristic were not recorded. The percentage of dropped ears was calculated by dividing the num- ber of dropped ears in a given plot by the number of plants in that plot. Stand. A count was made in late summer, at all fields, of the number of missing hills and number of missing plants in each plot of 1 All moisture determinations were made with a Steinlite or a Radson mois- ture tester. a Cochran, W. G. "Some Additional Lattice-Square Designs." Iowa Agr. Exp. Sta. Res. Bid. 818. May, 1943. 12 BULLETIN No. 598 [January, each variety. It is assumed that missing hills were due to some factor other than the hybrid itself. Yields were corrected for missing hills by the following adjustment: Ear weight in field X ( 1 + ^ mg hlll f X .6^) = adjusted ear weight. \ hills present / The percent stand is based on the total number of missing plants in relation to the number that would have been present if all the kernels had produced plants. Stand differences may be due to poor germina- tion, to disease, insect, or rodent destruction, or in some cases to destruction in cultivation. Readers are urged to keep in mind these two things when comparing the performance of hybrids on any one field: 1. Small differences in any one year do not necessarily indi- cate that one hybrid is inherently superior to another. In com- paring the performance of two hybrids, figures may be obtained representing the range which differences between two entries must exceed before they can be considered significantly different. The method used in determining this value is called the "Mul- tiple Range test." 1 This method considers the number of entries that fall within the range as well as the variability of the test. It has been used in presenting the data from the five main tests discussed in this bulletin (Tables 4, 5, 6, 7, and 8). In each of these tables, the performance of the highest-yielding hybrid and of all entries not significantly different from it in yield are shown in boldface type. For each characteristic other than yield, the "difference necessary for significance" or "least significant differ- ence" has been computed in the conventional manner. 2. Tests covering three years (see upper part of yield tables) give more reliable results than those covering only one year. The fact that a hybrid does not appear in the summary is, however, nothing against it its absence merely means that 1955 was the first year it was tested or that it missed one year of the series. 1 DUNCAN, D.

Growing conditions were generally excellent at all locations, although wet weather delayed planting unduly at Brownstown and Carbondale, and late-season moisture shortages probably caused some reduction in yields at DeKalb, Brownstown, and Carbondale. 1955 yields. The Galesburg field, in western north-central Illinois, had the highest average yield, 108.2 bushels per acre. The average yield at Urbana, in central Illinois, was close behind at 107.3 bushels per acre. Average yields per acre on the other three test fields were: DeKalb, 84.7, Brownstown 58.7, Carbon- dale 81.7. The average yield of all hybrids tested was 89.9 bushels. This was nearly 8 percent above the 1954 average, and was the second highest average yield ever recorded in these tests. It has been exceeded only by the record average of 92 bushels in 1948. Only the DeKalb field had a lower average yield than the correspond- ing test in 1954. Three-year summaries, 1953-1955. The highest-yielding hybrids in the three-year summaries were the following : Northen Illinois Hulting 238, P.A.G. 234, Illinois 1091 A (Dittmer), Sieben S-340, Holmes 11 A, Munson M-5.

Lodging. Approximately 90 percent of the plants in the tests at DeKalb, Galesburg, and Carbondale were erect at harvest. Lodging, mostly in the form of stalk-breakage, was severe at 1956] ILLINOIS CORN TESTS : 1955 25 Urbana and very severe at Brownstown. More than 70 percent of the plants in the Brownstown test were lodged at harvest. Significant differences between hybrids in percentage of plants erect at harvest were observed at all locations. Moisture. The average moisture content in the grain aver- aged 20.8 percent for all hybrids tested. Average moisture per- centages were below 21 percent at the three southernmost locations, but above 23 percent in both northern tests. Stand. The average stand obtained for all entries tested was 89 percent. Disease damage. Stalk rots were severe on the test fields at Urbana and Brownstown, resulting in serious late-season stalk breakage. Only sporadic occurrence of stalk rot was noted on the other three test fields. Data on disease prevalence and estimates of losses for the state are again included. Charcoal Rot, normally a relatively un- common disease in the state, caused more damage than ever previously recorded. Diplodia and Gibberella stalk rots also were unusually severe in 1955. Seed-treatment test. Highly significant increases in yield were observed to result from seed treatment in a test involving three dates of planting. Increases in stand from treatment were greatest in the latest-planted corn, but increases in yield were greatest for the earliest planting date. The average increase in yield from all treatments was 9.7 bushels, or 9.3 percent. 26 BULLETIN No. 598 [January, CONTRIBUTORS OF SEED AES Hybrids AES 805 (111. Agr. Exp. Sta.)
