PERFORMANCE OF SMALL GRAIN VARIETIES IN NORTH CAROLINA

John C. Rice, E. L. Jones, G. C. Oliver, Ray Adams

1/

INTRODUCTION

The Official Variety Test on Small Grain varieties in North Carolina

is conducted annually by locating evaluation trials throughout the small

grain producing area of the state. These tests are conducted to determine

the value and suitability of commercially available and prospective

varieties of wheat, oats and barley for planting in North Carolina. The

results of these tests are intended to aid the growers and agricultural

workers in the selection of a variety best suited for their particular

area of the state or region.

In North Carolina the wheat production for the 1970-71 season is

expected to be 9,912,000 bushels. This production will be harvested

from 236,000 acres estimated to be 28% above the previous season's

acreage. The North Carolina production for the current season is

expected to be up 25% from the 1970 production. For 1971, the state

average yield for wheat is estimated to be 42 bushels per acre, one

bushel below last year's record yield but equal to the previous record

yield set in 1969.

The North Carolina acreage of oats planted for 1970-71 and spring

planted oats in 1971 totaled 253,000 acres. This acreage was seven

percent above the 236,000 acres planted for the 1970 crop. All small

grain acreages in North Carolina are higher for 1971, due in large

measure to the short corn crop in 1970.

Barley production for 1970 was 3,276,00 bushels and the 1970-71

crop was planted on 63,000 acreso The 1970 yield was 19 percent above the

1969 production. Yield per acre in 1970 averaged 52 bushels per acre,

an increase of two bushels over the 1969 average.

Information on varietal performance is presented from six test

locations in the state, three in the Piedmont and three in the Coastal

Plain Area. In comparing the performance of varieties, data from the

area which most nearly represents the growers' conditions should be used.

Seasonal conditions differ from year to year; therefore, a variety which

looks superior for one year may not be consistently good, hence,

varie-ties should be evaluated on the basis of performance over several years.

Depending upon the release date of the entry, data are presented for

performance from one to five years. All available datal/were used in

determining the pathologic and agronomic characteristics of the varieties.

Cultural Practices

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 1. Several

months prior to planting each test location, soil samples were obtained

for the test field and fertilizer requirements made in accordance with

the soil analysis report. Lime was applied, if needed, to adjust the

pH to a desirable level for small grain production.

Starting in 1969 all tests were planted with cone-type,

tractor-mounted, spring-loaded disc equipment. The disc allowed for more accurate

seeding in areas with stubble or organic matter on the soil surface. The

seeding rate was one gram per foot of row. The rows were spaced one foot

apart. Each plot consisted of seven rows, 15 feet long with the two

out-side rows used as borders. The border rows were removed prior to harvest

and only the five center rows were harvested. The date of planting and

fertilization at planting is shown in Table 1 for each test location.

A seven foot combine was modified slightly for harvesting individual

plots. Grain from individual plots was collected as it carne from the

elevator and weighed. The combine was stopped at the end of each plot

for a short interval of time in order for the machine to clean out

between plots prior to weighing the grain from the plot. A sample of

grain was taken from each plot for the determination of test weight

and moisture. All plots were adjusted to 13% moisture. All barley samples

were run through a small thresher to remove the awns prior to taking test

(8)

under which these varieties would be harvested on farms and it appears

to give very satisfactory results.

Seasonal Conditions

The 1970-71 small grain growing season in North Carolina was

generally conducive for good growth and high yields. The six locations

for the 1970-71 Official Variety Test, three in the Piedmont and three

in the Coastal Plain Area of the state, were selected to represent small

grain production areas.

October 1970: It was dry during the early part of the month but

showers across the state loosened soil and allowed farmers to prepare

for seeding Official Variety Tests. Tests were planted on recommended

dates and good stands were obtained.

November 1970: Temperatures were normal for most of the month.

On the last seven days near-record readings, both on the high and low

side occurred. As a cold wave moved into the western part of the state

and spread to the coast, temperatures ranged from 10 degrees below zero

to the upper seventies during the day. This was a range of 90 Fahrenheit

degrees.

Rainfall was scant over most of the state during November. Nearly

half of the measuring stations had less than two inches and several

places had less than one inch.

December 1970: December was a fair weather month with little

precipitation during the latter half of the month. Average temperatures

(9)

January 1971: This month was colder than average but less severe

than the record breaking January of 1970. Average temperatures for the

month were two to four degrees below normal. Rainfall varied from one

and one-half inches to nine inches with the average for the state near

normal. Rain was reasonably well distributed throughout the state.

February 1971: Average weather was quite close to normal. It

was the warmest February in five years, but the temperatures were below

normal most of the time until the 16th. Rain was frequent with the

total in most areas near or a little more than normal.

March 1971: March was more windy than usual with average sunny

skies and abundant precipitation. An unusually late season and snow

affected nearly all of the state on the 25th and 26th. Average

temper-atures were mostly around four degrees below normal.

April 1971: April is usually the month showing the most rapid

rise in temperature of the year, but the 1971 April warmed up very littleo

Average temperature at the end of the month was the same as at the

beginning. Freezing weather was reported as late as the 30th at some

places. Average temperature for the month was two to five degrees

below normal. It was the coldest April since 1961. Rainfall was fairly

uniform over most of the state ranging from two to four inches.

May 1971: May showed very slow progress in the advance of the

spring season. Average temperatures were five degrees below normal and

the last week in May was cooler than the third week. These conditions

(10)

All locations in the Official Variety Test were planted on

schedule according to recommended seeding dateso A good seed bed

was present at each locations and this resulted in extremely excellent

stands. The specific planting dates, fertilizer, topdressing and harvest

dates are shown in Table 1. Lodging data was obtained where lodging

(11)

RESULTS AND DISCUSSION

The performance of the 1971 tests along with the previous four

years are presented by crop and area in a tabular form in this report.

Since the genetic expression of a variety is influenced greatly by the

environment, it is best to have several years' data from which to draw

conclusions. For example, if a variety appeared in the two-year average

but not in the three-year average, then it must be compared only within

the two years and not with the data in the three-year average since it

is possible that the third year could have been extremely good or poor

and not comparable.

The 1971 data presented in this report have been analyzed

statis-tically and the least significant difference (L.S.D.), in terms of

bushels per acre and pounds per bushel is given. Unless the difference

between two varieties is greater than the L.S.D., the varieties should

not be considered as being any different statistically.

Barley

Table 5 shows the performance of barley in the Piedmont. The

yields varied from a high of 88.9 bushels per acre for the variety

Rapidan and experimental line, NC 83, to 73.2 bushels for the variety,

McNair 601, for the 1971 season. A five-year average also showed the

variety, Keowee, to have the highest yield at 85.6 bushels per acre.

The test weight of 47.9 and 47.6 pounds per bushel for the varieties,

~eowee and Barsoy were the highest for the 1971 season. Keowee also

(12)

Harrison was very close with a 47.7 average for five years. All test

weights were lower for the 1971 season than for the 1970 season.

In the Coastal Plain Area, Table 6, shows the difference in yield

between varieties. The variety, Clayton, yielded higher than other

entries with an average of 84.7 bushels per acre for the 1971 season.

The Barsoy variety had the highest test weight with an average of 48.4

pounds per bushel. Most test weight data was lower than for the 1970

season.

Over the five-year average, the variety, Keowee, had the highest

yield at 80.6 bushels per acre and Harrison had the highest test weight

with an average of 48.3 pounds per bushel.

Oats

The data from the oat trials in the Piedmont are presented in

Table 7. The yields for 1971 were somewhat lower than in 1970.

Va. 65-32-21 was the highest yielding with an a'verage of 126.2 bushels

per acre. The test weights were much lower with NC 161 having a top

of 35.4 pounds per bushel.

Yancey had the highest five-year yield with 107.9 bushels per

acre while Coker 242 had the highest test weight of 36.1 pounds per

bushel.

In the Coastal Plain Area, Table 8, the oat yields varied from a

high of 119.9 bushels per acre for Ora to 75.1 bushels for Yancey.

There was a difference of 44.8 bushels per acre between the high and

(13)

pounds per bushel. Over a five-year average, Ora had the highest

yield of 108.8 and also had the highest test weight of 37.3.

Wheat

Table 9 shows the data on the wheat trials in the Piedmont. The

experimental line, NC 7, had the highest yield with 67.6 bushels per

acre. Coker 68-15, with an average of 58.2 pounds per bushel, had the

highest test weight.

Over a five-year period, Blueboy had the highest yield of 68.9 and

Coker 65-20 had the highest test weight of 59.5 pounds per bushel.

The Coastal Plain data are presented in Table 10. NC 7 led the

test with an average of 65.8 bushels per acre. Arthur had the best

test weight with 58.7 and all test weight data were below the 1970

season.

Blueboy and Coker 65-20 were the only two varieties tested for

f~ve years. Blueboy had an average of 61.0 bushels per acre and Coker 65-20 had an average test weight of 56.5 pounds per bushel.

Lodging

Lodging data are given in Table 11. A one-year, two-year, three-year

and four-year comparison is shown with notation giving the number of

locations where lodging occurredo In 1971 a total of six locations was

used for lodging data. If no lodging was recorded at a specific location,

data on this location was used for the average along with percent lodging
