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 vari.eties 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.

Winter wheat production in North Carolina for the ·1978-79 season is

forecast at 7,000,000 bushels as of June 1. This would be an increase of 18.0

percent over the 1978 crop. Acreage to be harvested for grain is estimated at

195,000 which is the same as the 1978 harvested acreage.

It is estimated that the yield per acre for the 1979 crop will be 36

bushels per acre. This would be an increase of three bushels from last year.

This year's crop is better than recent years due to adequate soil moisture and

almost no winter kill.

The United States winter wheat production is forecast at 1.39 billion

bushels, 11 percent above the previous yield last year. The yield of 32.0

bushels per acre is the same as for the 1978 average.

In North Carolina the oat acreage planted during the Fall of 1978 and

Spring of 1979 was 160,000 acres. This was 25,000 acres less than last

year's planted acreage and fourteen percent below the 1978 crop.

The U. S. seeding of oats for the. 1979 crop is expected to total over

15.0 million acres based on growers' intentions as of March 1 of this year.

This would be 92 percent of the 1978 acreage.

In 1978 the barley production in North Carolina was harvested from

59,000 acres with a yield of 51 bushels per acre. The 1977 acreage. was

55,000 acres. The 1978 yield per acre of 51 bushels was up eleven bushels

from the previous year.

Information on varietal performance is present 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 mO$t nearly

represents the grower's 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, varieties 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

21

data- 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 were 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 changed to seven inch spacing in

1979. Each plot consisted of seven rows fifteen feet long with two feet

between each plot. The datesof planting and fertilization at planting are

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 came 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 percent moisture. All samples were run through a small thresher to

remove the awns and foreign matter prior to taking test weights. The combine

was used to more nearly simulate the conditions under which these varieties

Seasonal conditions

The seasonal conditions during the Fall of 1978 and Spring of 1979 were

characterized by variable weather which had an influence on small grain production.

Yields were somewhat normal to sub-normal with one location, Rowan County,

having the most ideal growing season.

September 1978: Following a dry August in the Eastern part of North

Carolina, September continued on the dry side with extreme dry conditions in

the Coastal Plain area. No precipitation occurred in Perquimans County during

August or September. Temperatures averaged well above normal across all

sections of the state.

October 1978: This is the month for planting small grain in North

Carolina and the weather conditions continued on the dry side of normal.

Rainfall averaged less than one tenth of an inch statewide during the week

of October 30. All 16 reportin.g weather stations in the state listed a "minus"

reading on precipitation departure from normal from September 1.

November 1978: Tar Heel farmers had a good month for field work as dry

and open weather continued. In some areas extremely dry weather hampered

germination of the small grain crop. Prospects at this date for wheat, oats

and barley were poor to fair due to very dry conditions. This resulted in

delayed seeding in many areas as well as poor germination.

December 1978-January 1979: Temperatures in December averaged from three

to six degrees below normal and precipitation totaled one-half to one inch in

the west and central and up to three and a half inches on the coast. In

January temperatures averaged two degrees above normal and rainfall continued

over most of the state. Mild weather prevailed and fair weather was the rule

(10)

8

February 1979: This month was characterized by extremes of snowfalls

and mild weather. Two winter storms gave measurable snowfall to most areas

of the state during the week of February 12. Heavy snow fell from the

Mountains to the Piedmont with the southeastern part of the state receiving

one inch before precipitation changed to freezing rain. Temperatures averaged

7 to 10 degrees below seasonal normals statewide. Total snow on the ground

by end of February 21 ranged from 7 to 17 inches in the mountains; 5 to 13

inches in the Piedmont; and 1 to 5 inches through the Coastal Plains. Even

the Coastal section had one inch of snow on the ground.

March 1979: Temperatures fluctuated rapidly during most of this month.

Thermometer readings dipped to ten or more degrees below normal as each cold

front moved across the state. However rapid warming took place each time

after the cold front moved through and temperatures rose to 5 to 10 degrees

above normal before the influx of the cold air.

April 1979: Temperatures averaged almost 15 degrees above normal during

the first part of the month. Favorable weather continued during the month

allowing ample opportunity for field work. The condition of wheat, oats, and

barley was reported as fair to mostly good. Soil moisture was reported as

13% short, 71% adequate, and 16% surplus statewide. Spring weather prevailed

across the state with warm temperatures and beneficial rains. A heavy freeze

on April 20 damaged entries in the Orange County test.

May 1979: This was the month for rain and scattered showers. Overall

crop conditions generally were fair to mostly good. General rainfall during

the last week caused some erosion and water damage. Days for field work

averaged 3.4 statewide compared with 4.6 during the early part of the month.

Rainfall continued to hamper field activities during the last week of May

(11)

June 1979: Combining of wheat, oats, and barley continued during the

second week in June. The average percents harvested for the state by June 1

were as follows:

Soil moisture varied across the state with the Mountains and Coastal

Plains Regions reporting mostly adequate soil moisture while the Piedmont

Region reported adequate to surplus supplies. Statewide, conditions averaged

5% short, 70% adequate, and 25% surplus.

General 1978-1979: The 1978-79 small grain season was characterized by

a dry fall, a normal winter, and a wet spring. Low temperatures had a killing

effect on oat varieties not resistant to cold damage. Some oat entries in

the Eastern part of the Coastal Plain were completely destroyed. Wheat and

barley entries did not suffer to the same degree as oat entries. Small grain

yields were average over most of the state. Diseases continue to be a major

RESULTS AND DISCUSSION

The performance of the 1979 tests, along with the previous four years,

is 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-year 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.

Barley

Table 5 shows the performance of barley in the Piedmont. Yields were

slightly higher than last year varying from a high of 84.0 bushels per acre

for the experimental NC 75-75 to 49.8 bushels for the experimental NC 75-149

The mean of the test for the 1979 season was 67.7 bushels per acre compared

with 65.6 bushels per acre in 1978.

The test weight of 47.0 and 46.8 for the experimentals NC 75-75 and

NC 73-119 respectively were the highest test weight in pounds per bushel of

all entries. Boone had the highest five-year average of four entries common

to the test for this period of time with 75.5 bushels per acre and Keowee

continued to have the highest test weight with 46.4 pounds per bushel. The

yield and test weight data for barley performance in the Piedmont are

averagesof Stanly and Rowan Counties.

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

between varieties and breeding lines. The mean of the test in bushels per

(13)

The highest yield was from the variety, Boone, at 69.5 bushels per acre.

The test weight in pounds per bushel on the eleven entries varied from

38.6 to 46.9 with a mean of 41.6. The mean test weight for 1978-79 season

was 4.3 pounds less than last season's test weight. The variety, Keowee,

showed the highest test weight at 46.9.

Oats

The data from the oat trials in North Carolina are recorded in Tables

7 and 8.

Entries in the Piedmont oat test were very good in 1979 compared with

1978. The mean yield of the test was 109.8 bushels for two locations with

an increase of 16.3 bushels over last year.

The highest in yield was Coker 716 with 125.2 bushels per acre and

another Coker variety, 227, was second at 119.6 bushels per acre. Coker 716

also had the highest test weight with 35.4 pounds per bushel.

In the Coastal Plain the mean yield of the test was 85.3 bushels for

three locations. This was 39.0 bushels less than last year. The mean test

weight was 32.7 pounds per bushel which was 1.2 pounds per bushel less than

1977-78. Salem and Brooks were on top at 95.8 bushels per acre. The highest

test weight on nine entries was 34.8 pounds per bushel for Coker 227. These

combined data were from tests in Wayne, Washington and Perquimans Counties.

Wheat

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

(bu/A) of the test for the 1979 season was 10.6 bushels more than in 1978.

The mean test weight in pounds per bushel for 1979 was 55.6 compred with 59.8

(14)

12

acre. The highest test weight was on Coker 747 at 57.4 pounds per bushel.

In the five-year average Coker 747 was also high with 51.7 bushels per acre.

The wheat yields in the Coastal Plain Area were down compared to last

year. The mean of the test decreased from 62.2 bushels per acre as the

mean of 1978 to 45.6 bushels per acre for the 1979 mean. This was a

16.6 bushel per acre decrease.

For the four-year average, the' variety, McNair 1003, was the highest

yielding entry at 56.7.
