FINLEY* THE LARGEST CORN CROP in Illinois' history was harvested in 1956. Official estimates placed total production at nearly 600 million bushels, more than 30 million above the previous production record set in 1948. The estimated average yield for the state was 68 bushels per acre, 12 bushels above the 1955 average and 7 bushels higher than the 1948 record. 2 PLAN OF THE TESTS Number of hybrids and their sources. Three hundred fifty-two hybrids were grown on seven major test fields. Fifty-five companies and individuals and the Illinois Agricultural Experiment Station fur- nished seed for the tests. Both the number of hybrids grown and the number of companies and individuals furnishing seed were substantially greater than in the past few years of the tests. One hundred twenty-five hybrids were grown at Galesburg and Urbana. One hundred entries were tested at DeKalb and Ashkum, and ninety hybrids were included in the test at Greenfield. Eighty-one hybrids were tested at Brownstown, and seventy-two at Wolf Lake. The test fields at Ashkum and Greenfield were new locations, intended to represent major corn-growing areas of the state which had not been adequately covered by the previous testing program. General informa- tion on the seven tests is summarized in 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. A fee is charged for testing hybrids nominated in this manner. In the past two years, all hybrids nominated for testing have been accepted and included in the performance test plots. 1 EARL R. LENG, Associate Professor of Agronomy, and DON E. FINLEY, Crops Testing Technician, Department of Agronomy. 2 Estimates of yield for the state were furnished by the Illinois Cooperative Crop Reporting Service, Illinois State Department of Agriculture cooperating with the U.S. Department of Agriculture. 4 BULLETIN No. 605 [January, Certain hybrids were also included in the tests to meet the field- performance requirements for certification. Some 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 1956 and preceding years is reported in Illinois Bulletin 606. Table 1.

Tests in DeKalb and Champaign counties were located on University of Illinois farms managed by R. E. BELL and C. H. FARNHAM. P. E. JOHNSON, Assistant Professor of Soil Fertility, supervised field operations on the test in Fayette county. Soil characteristics of fields. 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. Approximate locations of test fields are shown on the map on the cover. Soil characteristics and manage- ment are described in Table 2. Field-plot design. The experimental designs used at DeKalb and Ashkum were 10 X 10 lattices, with 3 replications each. A 9 X 9 lattice-square design with 5 replications was used at Brownstown. The designs used at Galesburg and Urbana were 5X5X5 cubic lattices, with 3 replications each. A 9 X 10 rectangular lattice with 3 replications was used at Greenfield, while the design at Wolf Lake was an 8 X 9 rectangular lattice with 3 replications. Because of time limitations, the data presented in this bulletin for all tests except Brownstown were analyzed by the procedure normally used for randomized block tests, rather than by the full procedure for rectangular or cubic lattices. Method of planting. All test fields were planted by hand on land prepared in the normal way for corn. Individual plots consisted of 2 rows each 5 hills long. Four kernels were planted per hill at DeKalb, .7957] ILLINOIS CORN TESTS: 1956 5 Ashkum, Galesburg, and Urbana; 3 kernels were planted per hill at Greenfield, Brownstown, and Wolf Lake. The plots were not thinned. GROWING CONDITIONS The 1956 growing season in Illinois was exceptionally favorable for corn. Moisture shortages were evident in the central and western sections during May and June, but timely rains and cool temperatures during July and early August provided favorable conditions which led to record yields. An unusually early killing frost extended over much of the northern half of the state on September 19 and 20, but nearly all corn was safely matured by that time, and no loss in yield resulted. The cool period in mid-September was followed by several weeks of exceptionally dry and warm weather, which resulted in rapid drying of the corn crop, and in unusually low moisture content of the grain at harvest. Harvest throughout the state was completed several weeks ahead of the normal schedule. Seedbeds for the performance tests were generally in excellent condition, except at Galesburg and Brownstown, and planting was timely, except at Brownstown. The seedbed at Galesburg was cloddy and dry at planting time, but ample rains fell soon after planting, and stands were generally good. Planting at Brownstown was again de- layed until the first week in June because of excessive soil moisture. Moisture supplies and general growing conditions in July and August were exceptionally favorable at all locations, although a slight deficiency of moisture was evident late in the growing season at Brownstown and Wolf Lake. The low temperatures on September 19 and 20 killed the majority of the plants in the DeKalb and Ashkum test fields, and also caused obvious frosting at Galesburg. No apparent reduction in yield resulted from this frost, since maturity was well advanced in all tests. Subse- quently drying conditions were exceptionally favorable, and moisture content of the grain at harvest was unusually low at all test locations. Damage by insect pests and plant diseases was light to moderate on the test plots in 1956. Moderate infestations by the European corn borer were evident in the four northernmost test fields but resulted in very little stalk breakage or ear droppage. The leaf blight phase of Stewart's disease was evident at Greenfield and Brownstown, but appeared to cause little if any reduction in yield. Stalk rots were preva- lent in most of the test fields, but very little stalk-breaking resulted at any test location. BULLETIN No. 605 [January, Table 2.

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 Brownstown 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 Galesburg and Urbana tests. Ear-dropping may have resulted from European corn-borer damage or from other causes. There were very few dropped ears in the other test fields, and so data on this characteristic were not recorded. The percentage of dropped ears was calculated by dividing the number 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 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: (missing hills \ hills present ) = adjusted ear weight. 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- 1 All moisture determinations were made with a Radson moisture tester. 2 Cochran, W. G. "Some Additional Lattice-Square Designs." Iowa Agr. Exp. Sta. Res. Bui. 318. May. 1943. 8 BULLETIN No. 605 [January, 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 indicate that one hybrid is inherently superior to another. In comparing 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 determin- ing this value is called the "Multiple Range test." 1 This method consid- ers the number of entries that fall within the range as well as the vari- ability of the test. It has been used in presenting the data from the tests discussed in this bulletin (Tables 3 to 9, inclusive). 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 difference" 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 1956 was the first year it was tested or that it missed one year of the series.

Growing conditions were exceptionally favorable, and record yields were produced at all test locations. 1956 yields. The Urbana test field, in east-central Illinois, had the highest average yield, 127.8 bushels per acre. Average yields on the other test fields were:*DeKalb 117.3, Galesburg 124.0, Ashkum 123.8, Greenfield 121.8, Brownstown 95.3, and Wolf Lake 104.5. The average yield of all hybrids tested was 116.4 bushels. This was by far the highest average on record for these tests. The average yield for the five test locations comparable with the 1955 locations was 27 percent higher than the 1955 average and 24 percent higher than the previous record average set in 1948. Each test location produced the highest average yield in the history of performance testing in its comparable area. Three-year summaries, 1954-1956. The highest-yielding hybrids in the three-year summaries were the following: Northern Illinois Hulting 238, Pioneer 354, P.A.G. 277, Sieben S-340, Frey 410, P.A.G. 244. West North-Central Holmes 39, Pioneer 313B, Schwenk S-34, Moews 520, Tiemann T-78, Schwenk S-24. East-Central Holmes 39, Appl A-159, Funk's G-95A, Canterbury 420, Frey 692, Bear OK-69.

Two test locations, Ashkum and Greenfield, were included in the testing program for the first time in 1956. The six highest-yielding hybrids in each of these two tests were the following: East North-Central DeKalb 632, Pioneer 313B, Schwenk S-27, U.S. 13 (Station), Pioneer 316, Wyckoff W-46A. West South-Central Pocklington P-75A, Whisnand 852, Ains- worth X-14-A, Pocklington P-78A, Producers 921, Producers 1022A. Lodging. Nearly all plants were erect at harvest in every test field; the general average for all hybrids tested was 97 percent plants 26 BULLETIN No. 605 [January, erect at harvest. Statistically significant differences between hybrids in lodging were observed at Galesburg, Ashkum, Urbana, and Greenfield. Moisture. The moisture content of the grain at harvest was far below normal, averaging 16.0 percent for all hybrids tested. The grain of most hybrids at Greenfield and Wolf Lake, and many at Galesburg, was dry enough at harvest to have been sold directly as No. 1 corn. Despite the fact that harvest of the test plots was completed by No- vember 1, only a few hybrids at the two northernmost test locations had moisture contents as high as 20 percent at harvest. Stand. Stands were generally good to excellent at all locations. The average stand for all entries tested was 88 percent, which com- pared favorably with average stand percentages in preceding years of the tests. Statistically significant differences between hybrids in stand percentages were found at DeKalb, Urbana, and Brownstown. CONTRIBUTORS OF SEED AES Hybrids. . . .AES 702 (111. Agr. Exp.
