PERFORMANCE OF CORN HYBRIDS, CORN SILAGE, GRAIN SORGHUM AND SOYBEANS IN NORTH CAROLINA

INTRODUCTION

with the large number of commercially available and prospec-tive hybrids and varieties of corn, grain sorghum, and soybeans, i t becomes difficult for growers to select a superior variety suited for their particular area of the state and their individual farming operations. To make this decision, the growers need up-to-date, unbiased, reliable information. The Official Variety Testing Program, through this report, seeks to provide that type of information.!!

The first section of this report is concerned with corn hybrids in all production areas of the state. The second section deals with corn silage. The third section includes data on grain sorghum. The fourth section covers data on soybeans. Each part is complete in that it contains information on experimental procedure, locations of the tests, a discussion of the data for

1985,~

!/The Official Variety Testing Program recognizes the cooperative spirit and civic-minded service rendered by the farmers who have furnished, prepared, and cultivated the land for these trials. Research technicians,

Ray Adams, Dwight Parrish, and G. C. Oliver, assisted in conducting these tests. Carey Parsons prepared the text for this bulletin.

It is hoped that the organization of this bulletin will provide data in a complete form to those interested in the various crops.

Growers are cautioned against making varietal selection decisions based on an individual location in anyone year. True varietal performance may have been masked by the unusual weather conditions experienced at anyone location or anyone growing season.

Comparing Hybrids and varieties

Performance of a hybrid or variety cannot be tested with absolute precision. Even though the tests are conducted in a uniform manner, as much as possible, uncontrollable variability exists among experimental plots due to soil type, fertility, moisture, insects, diseases, and other sources of variation. Because this variability exists, statistics are used as a tool to determine differences among hybrids and varieties. The size of difference among hybrids or varieties which may have been due to chance variation is listed in each table as the L.S.D. (least significant difference) and those hybrids or varieties which do not differ by more than the L.S.D. are statistically not different. Those hybrids or varieties that do differ by more than the L.S.D. are statistically different. The Bayes L.S.D. at the K-ratio of 50

(approximately .10 level of probability) was used.

well the true mean was estimated. The formula for the s.e. is the

square root of the error variance divided by the square root of the

number of replications. The error degrees of freedom (Error d.f.)

used to test varieties or hybrids are listed along with the mean of

the test.

Hybrid or varietal performance may appear inconsistent among

locations within an area or among years in a particular area, thus

it is important for the reader to examine results from more than

one location within an area or more than one year at a particular

area to obtain a more accurate picture of relative hybrid or

varietal performance. An effort has been made to facilitate

comparisons among locations and across years in this report.

The hybrids or varieties which do not yield significantly less

than the highest yielder are denoted by an asterisk (*) next to their yields; the highest yielder is denoted by a double asterisk

(**) next to their yield. The relative performance of a hybrid or variety across locations within an area can be easily evaluated by

going across the table; those hybrids or varieties which are most

frequently marked by an asterisk would be highly desirable. Other

agronomic characteristics may be as equally important as yield.

It is suggested that the grower plant a small number of acres

in a new variety when first determining if i t is adapted to his

CORN HYBRIDS

The performance of various corn hybrids in different areas of the state depends on their adaptation to the environmental

conditions within the area. The performance of hybrids across the state of North Carolina is reported in this bulletin.

Entries: Any individual or firm may make application for having hybrids tested. A fee is charged on an entry basis. Personnel of the testing program may also include entries about which further information is desired.

Early in January each year~ rules governing the tests for the ensuing year are distributed to all previous participants and to those who make iquiry.

Agencies or individuals entering hybrids in the Official Variety Tests were requested to designate the population and maturity range desired. Because of this, some hybrids may not

appear to be in the correct maturity group.

Agencies sponsoring entries in the 1985 tests are shown in Table 1.

Field Plot Technique: Eight tests were located across the state. The various locations are shown in Figure 1. Ear1y-maturi~g

corn hybrids (less than 110 days to maturity) are included in six tests in the Coastal Plain and Tidewater areas of the state. The medium-maturing (approximately 110 to 120 days to maturity) and the late-maturing (over 120 days to maturity) hybrids are included in all eight locations. It is important to remember that these are loose groupings, i.e. some hybrids may easily fit into either of two maturity groups due to it being on the borderline. Table 2 lists the cultural practices used and Table 3 lists the soil test results.

In field design a lattice was used. Each plot consisted of four rows 23 feet long with a 40, 38, or 36" row width. The center two rows were harvested for yield. Alley width was five feet.

In 1985, all tests were planted to a stand at 110% of the desired plant population.

late August delayed harvest and moisture readings at harvest reflect this delay.

Rainfall data at six locations reveal the type of season experienced in 1985.

Corn borer damage was more extensive in 1985 than had been experienced in years past. Northern corn leaf blight was evident at the Yadkin County test site. The McDowell County test site was specifically chosen for its past history of gray leaf spot and the disease was evident by mid-July; conditions became excellent for rating corn hybrids for their resistance to this disease. The Rowan County test was discarded due to a heavy infestation of Johnsongrass.

being 0-9 and 9 being 90-99% of leaves covered with the disease. Stand counts were reported in plants/acre. As a general indicator of seedling vigor, all corn hybrids were planted March 13 at one location and percent desired stand was later calculated.

Results: Seedling vigor ratings are listed in Tables 4, 5, and 6 along with their germination data. Germination was determined at the NCDA Seed Laboratory under supervision of Mr. George Spain. Yield and performance data for the early maturing hybrids are shown in Tables 7, 8, and 9. Funk's G-4522 leads the three and two year average in yield (Table 7). The number of locations reveals the number of data points that went into that particular average. Funk's G-4522 is also the yield leader for 1985 across locations and was followed closely by four other hybrids (Tables 8 and 9). The low average yields for Johnston and Sampson Counties are a result of the dry summer.

For the medium maturing group, two McCurdy hybrids lead the group for yield after three years; McCurdy 7676 is also the two year yield leader (Table 10). Tables 11 and 12 reveal 1985 data where 64 hybrids were entered.

Three Pioneer hybrids lead the late-maturing hybrids after three years (Table 13) and two of those three also have the highest two year averages. Again, Pioneer 3165 and Pioneer 3055 are the yield leaders in 1985 across all locations (Table 14 and 15).

realized that certain hybrids may yield better under gray leaf spot infestation than those hybrids with higher levels of resistance. This test was conducted on Ronnie Huskins' Farm in McDowell County; Mario Deluca, County Extension Agent, cooperated in this research.

CORN SILAGE

Silage is an important part of the beef and dairy cattle industry in North Carolina, particularly in the Piedmont and Mountain regions.

This report presents the results of the North Carolina Official Corn Silage trials for the 1985 season.

Entries: Any individual or firm may make application for having hybrids tested. Personnel of the testing program may also include entries about which further information is desired.

Early in January each year, rules governing the tests for the ensuing year are distributed to all previous participants and to those who make inquiry.

Agencies sponsoring entries in the 1985 tests are shown in Table 18.

Field Plot Technique: One test was located in Haywood County on a creek bottom and one in Rowan County on an upland soil.

Plots consisted of four rows with the center two rows harvested. Four replications were planted in a randomized, complete block design. Plots were 23 feet long with five foot alleys.

All plots were overp1anted and later thinned to the desired stand.

Table 19 lists the cultural practices used; Table 20 lists soil test results.

GRAIN SORGHUM

The majority of the grain sorghum in North Carolina is grown in the Piedmont with increasing acreage being grown in the Coastal Plain. In the Piedmont it i~ generally grown as a full-season crop while it is often double-cropped behind small grain or potatoes in the Coastal Plain.

Entries: Any individual or firm may make application for having entries tested. A fee is charged on an entry basis. Personnel of the testing program may also include entries about which further information is desired. '

Test Locations: Three full-season tests were located in the Piedmont with one double-crop test located in the Coastal Plain

(F igure 1).

Field Plot Technique: A randomized, complete block design was used with four replications at each full-season test. The

late-planted test had seven replications in a randomized complete block design. Plots were two rows 23 feet long on a 38" or 30" row width. Plots were overseeded and thinned to 5-6 plants per foot if necessary. Cultural practices are shown in Table 25. Table 26 lists soil test results.

Seasonal Conditions: Soil moisture was adequate at Rowan and Anson Counties but inadequate at Stanly County resulting in poor stands at that particular location. Consequently, the Stanly County test was discarded. The late-planted test at Washington County was discarded due to extensive bird damage and lodging. Below normal rainfall was experienced at Anson and Rowan County for much of the growing season; moreso at Anson than at Rowan. The Rowan test site received 2.71 inches of rainfall in May, 4.33 in June, 4.61 in July, and 6.47 in August.

Data: Data were collected on yield, moisture at harvest, head compactness, head exsertion, and plant height. All plot yields were adjusted to 14% moisture and reported in pounds per acre. A

description of head type was determined and indicated with "1" denoting a compact head and "3" denoting a loose head. Head

material hindering the operation. Date 50% flowered was collected at two test sites. Percent bird damage was collected at the full-season test sites.

Results: Table 27 shows the two year averages. Table 28 shows the 1985 data combined over locations, while Table 29 shows the individual location yield data. The average yield of 1204 pounds per acre at Anson County is a reflection of the severity of the summer drought. Table 30 shows the bird damage ratings of the

hybrids in alphabetical order. Although the top yielding hybrid had the least amount of bird damage, there seemed to be little

Test Locations: One full-season test was located in the Piedmont and four in the Coastal Plain; three late-planted tests were located also in the Coastal Plain and one in the Piedmont.

Data: Data were collected on yield, moisture, lodging, plant height, date of pod maturity, seed size, and oil percent. Yields were calculated on plot weight and adjusted to 14% moisture. Lodging was scored on a scale of 1-5 with "1" being no lodging and "5" being completely lodged. Plant height was determined by

measuring from the ground to the top of the plant prior to harvest. Date of pod maturity was observed when 95% of the pods turned brown. Oil percent was determined at the USDA Soybean Laboratory; appreciation goes to Dr. Rich Wilson and Jamie Fish for running these analyses.

Levels of worm populations, various species, were suffi-cient to require insecticide applications at most locations.

Cultural practices followed are listed in Table 32 while soil test results are shown in Table 33.

Harvest conditions were poor with many days in November being warm and humid. Consequently, soybeans were harvested later than normal. This delay in harvest resulted in seed deterioration in the pod. Test weights were very low.

Results:

Early-Planted Soybeans

Two and three-year averages for the early-maturity group (Group V) are found in Table 34. Coker 485 and Deltapine 105 led the averages followed closely by several other varieties. Table 35 shows the 1985 data. The drought was particularly severe on this group of soybeans at Halifax County resulting in an average yield of 13 bushels per acre.

Young is the three-year yield leader followed closely by RA 606 for the medium-maturing group (Table 36). Hartz 6383R joins Young as the yield leaders in the two-year average. Sampson,

52

Data for the late-maturing soybean varieties (Groups VII and VIII) are presented in Tables 38 and 39.

Late-Planted Soybeans

Deltapine 105 leads the three and two-year yield averages for the early-maturing soybeans (Table 40). It is also the yield leader for 1985 with 24 bushels/acre followed closely by Pioneer 9751 and Asgrow A5980 (Table 41). Yields were low in 1985 particularly at Johnston County.

NK S69-96 is the three-year yield leader while RA 606 and Deltapine 566 tie for the two-year yield leader in the medium maturing group (Table 42). Data for 1985 are presented in Table 43.

Coker 368 and Deltapine 417 tie in yield at 36 bushels/acre to lead the late-maturing varieties after three years (Table 44). Deltapine 417 leads the two-year average with 42 bushels/acre. An experimental, Coker 82-645, was the yield leader in 1985 across all locations (Table 45).

Two and three-year averages and 1985 data for date 95% pods brown are shown in Tables 46, 47, and 48. These two and three-year averages reflect a more accurate picture of the average date of physiological maturity than anyone year. It should be noted that the soybeans should be ready to harvest 10 days after the date 95% pods brown given optimum harvest conditions. Table 49 lists the oil percentage and seed size for entries in the full-season tests.
