PERFORMANCE OF SMALL GRAIN VARIETIES IN NORTH CAROLINA
INTRODUCTION
Across the state of North Carolina during the fall of 1991,
growers planted 35,000 acres of barley, 90,000 acres of oats, and
500,000 acres of wheat. Favorable planting conditions were
experienced in the fall.
with the large number of commercially available and
prospective varieties of barley, oats, and wheat , i t becomes
difficult for growers to select a superior variety suited for their
particular area of the state. To make this decision, the grower
needs up-to-date, unbiased, reliable information. The Official
Variety Testing Program, through this report, seeks to provide that
type of information.
Information on varietal performance is presented from seven
test locations in the state.1 Also included are multiple-year
performance data on a selected number of varieties.
2
COMPARING VARIETIES
Performance of a variety cannot be determined 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, fertility, moisture, insects,
diseases, and other sources of variation. Because this variability
exists, statistics are used as a tool to determine differences
among varieties. The size of difference among varieties which may
have been due to chance variation is listed in each table as the
B.L.S.D. (least significant difference). Those varieties which do
not differ by more than the B.L.S.D. are not statistically
different.
varietal performance may appear inconsistent among locations
within an area or among years at a particular location, thus i t is
important for the reader to examine results from more than one
location within an area or more than one year at a particular
location, to obtain a more accurate picture of relative varietal
performance. An effort has been made to facilitate comparisons
among locations and years in this report.
The varieties which do not yield significantly less than the
highest yielding variety are denoted by an asterisk (*) next to
their yields. The relative performance of a variety across
locations within an area can be easily evaluated by going across
the table; those varieties which are most frequently marked by an
asterisk would be highly desirable. other agronomic
character-istics may be as equally important as yield. All available data
3
are found in Tables 1, 2, and 3 for barley, oats, and wheat,
respectively.
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

EXPERIMENTAL PROCEDURE
The state is divided into physiographic regions and tests were
located in the Piedmont and Coastal Plain (Figure 1). Tests were
located on private farms and on research stations.2
Entries: Commercial varieties and experimental lines developed by
pubLic and private agencies are included in these tests. Any
individual or firm may make application for having entries included
by writing Official Variety Testing Program, Department of Crop
Science, North Carolina State University, Raleigh, N.C. 27695-8604.
A fee is charged on an entry basis for all private entries.
Entries of specific interest to North Carolina seedsmen may have
been included on a no-fee basis. A total of 9, 19, and 30
commercial varieties and experimental lines of barley, oats, and
wheat, respectively, were evaluated in the 1991-92 season.
Field Plot Design: A randomized, complete block design with four,
five, or six replications was used at each location.3 Each plot
consisted of eight rows, 7.5 inches apart, 19 feet long with 2.5
feet between each plot.
Crop Management: Cultural practices, such as seed bed preparation,
date of planting, fertilization and topdressing were in accord with
good farming practices and were uniform for all entries at a given
location (Table 4). Prior to planting each test, soil samples were

SEASONAL CONDITIONS
The 1991-92 small grain growing season was characterized by
normal rainfall in the fall which allowed planting to be on time
(Table 4). Above-normal temperatures through May were experienced
at all locations. Cool, damp weather was prominent during late May
and early June delaying dry-down and harvest. The weather was
responsible for greater than normal lodging in barley and oats.
Rainfall data at six locations are shown below:
Monthly Rainfall Totals (Inches)
14
Conditions were ideal for some diseases. Powdery mildew and
leaf rust were evident to the point where valid ratings could be
made. Barley yellow dwarf virus and soil borne mosaic were seen at
several locations. Cereal leaf beetle was also evident at several
locations although most locations did not require an application of
insecticide; the Rowan and Granville county locations were sprayed.
Glume blotch occurred at several locations in the Coastal Plain and
in the Piedmont.
DATA
Yield is reported in bushels per acre by location and area as
well as across years by location and area. Test weight in pounds
per bushel was reported by region and by location. One thousand
kernel weight for wheat was reported averaged across the state.
Lodging was reported in percentage averaged across all locations
within the state; the lodging data are for lodging prior to
harvest. All plots were adjusted to 13% moisture. Heading data
were taken at the Lenoir county location.
Disease ratings are reported in the state-wide averages
although they may have only been taken at one or more locations.
Yield data were analyzed. The average yield of each test was
indicated on the bottom of the tables. The B.L.S.D. K-50 is
equivalent to the Fisher's L.S.D. at the 10% level. The standard
error of the mean (s.e.) is an indicator of the precision of that
test; the smaller the s.e., the more precise the estimate of yield
is for any particular variety. The s.e. of the mean is equal to
the standard deviation divided by the square root of N; N is
normally the number of replications in the trials.
15
location, therefore, two and three-year averages may not appear to
equal the average between years when the number of locations varies
16
RESULTS AND DISCUSSION
Barley
statewide averages are shown in Tables 6 and 7. These tables
only show lodging, plant height, date 50% headed, and disease data
for entries common across all locations. NC 88-851 was only tested
in the Piedmont locations and had an average lodging of 64% and
plant height of 39 inches.
Individual location data, area data, and mUltiple year data are
shown in Tables 8, 9, 10, and 11. The barley plots suffered bird
damage at the Granville county location.
OATS
statewide average data are shown in Tables 12 and 13. the
variety 833 from Arkansas County Seed Company was not included in
the statewide average because i t was only tested in the Coastal
Plain locations; agronomic data of 833 were lodging 31%, plant
height 40 inches, and date 50% headed 4-26. Also, the
experimental, NC 881838, was only tested in the Piedmont locations;
i t had an average plant height of 39 inches and averaged 60%
lodged.
Individual location data, area data, and multiple year data are
shown in Tables 14, 15, 16, and 17. Plots at the Columbus county
location were damaged by birds. However, oat yields were excellent
at most locations across the state.
WHEAT
statewide averages are shown in Tables 18 and 19. The
following entries are not in the statewide averages since they were
only in one area: NK Coker 833, NC 88-2546, NK Coker 9907, and NK
17
while plant height averaged 39, 39, 37, and 36 inches respectively.
One thousand kernel weight averaged 31.4, 30. 3, 33. 2, and 31. 3 gms,
respectively. Date 50% headed was 4-21, 4-17, and 4-25 for NK
Coker 9907, NK Coker 9766, and NC 88-2546 respectively; powdery
mildew ratings were poor, poor, and good for these same three
entries while all three were rated good for leaf rust resistance.
Individual location data, area data, and multiple year averages
are shown in Tables 20, 21, 22, 23, and 24. Data from Columbus and
Stanley counties are not reported due to field variability. Three
varieties, Florida 302, GA Gore, and Saluda, were tested at all
locations with and without a systemic fungicide seed treatment and
the data are reported. All other entries were treated with a
systemic fungicide seed treatment at all locations. The Lenoir
county location included nearly all entries tested with and without
the systemic fungicide seed treatment and these data are reported
