* RESULTS QE THE KENTUCKY GRAIN SORGHUM
PERFORMANCE TESTS - 1961
J. F. Shane and H. R. Richards
1 The objective of the Kentucky Grain Sorghum Performance
Test is to provide an estimate of the relative performance
of grain sorghum hybrids and varieties.
This report presents yield and other agronomic data
obtained from grain sorghu  plantings made at various loca-
tions in the state. The grain sorghu  tests consisted of
18 hybrids and 7 varieties. Each hybrid or variety was
. planted in 2-row plots 10 feet long in each of 4 replications.
· When tests are grown near highly populated areas, which
serve as roosting places for birds, they are more subject to
attack by birds than they are in open fields. The test at
Lexington was harvested early to avoid damage by birds and
eliminate the necessity of bagging or standing guard with a
;, shotgun.
` Only one replication of the test at Franklin was harves-
ted because of heavy infestation of foxtail in the remainder
of the test. Individual plot data indicate yields were well
over the 100 bushel per acre level.
im Average yields for the tests at Princeton and Lexington
were 94.7 and 119.8 bushels per acre, respectively. The av-
erage yield for both locations was 107.3 bushels per acre.
The following tables present three-year and one-year
summaries for Princeton and Lexington. Data for results at
Franklin, Ky. are available in previous reports.

 EXPLANATION OF TERMS USED IN THIS REPORT k
l. Yield. Yields of grain sorghum are reported as bushels C
per acre of threshed grain at 13.0 percent moisture and
56 pounds per bushel. Adjustments were made for bird
damage and for significant variations in stand.
2. Moisture. Samples for moisture determinations were
taken from the bulked grain of all replications.
3. Height. The distance from the base of the plant to the
top of the plant is reported in inches. V
4. Head Exsertion. The distance between the top leaf and
the base of the head. This characteristic is reported
as G - good, F · fair, and P - poor. Varieties with ·
good head exsertion are more easily combined because
less plant material will be passed through the combine.
5. Lodging. Plants leaning at an angle of more than 30
degrees from the vertical are considered lodged.
6. Test Weight. Test weight or weight per bushel is one Y
of the quality factors used in determining the grade
that is assigned in com ercial marketing of grain.
The higher the test weight, the higher the market
value unless the grain is down-graded by another factor.
7. Date Flowered. The number of days after July 1 when 50 ,*
percent of the heads have flowered.
8. L.S.D. The abbreviation "L.s.d." means least signifi-
cant difference. Two varieties differing in yield by
less than the L.s.d. cannot be said to differ in yield
in that particular test if one wishes to be correct at
least 95 percent of the time. '
9. Head Type. Heads are classed as O·open, I-intermediate
or C-compact. Open type heads are more desirable since
they are less likely to mold and harbor insects.
