 RESULTS QF THE KENTUCKY GRAIN SORGHUM
PERFORMANCE TEST - 1964
J. F. Shane and Leo A. Link
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 ob-
. tained from a grain sorghum planting made at Princeton, Kentucky.
The grain sorghum test consisted of 18 hybrids and 7 varieties.
Each hybrid or variety was planted in 2-row plots 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. Field data for
the test were not adjusted for the minor damage which did occur.
The average bushel per acre yield for the test was 73.8 V
— bushels. The average yield for the hybrids was 74.6 bushels per
acre and that for the varieties 71.9 bushels per acre. Tempera-
tures in excess of lOO°F for several days during flowering may
have had an effect on seed set.
The 1964 data are presented in Table 1 and that for the
two-and three—year summary in Tables 2 and 3.

 EXPLANATION OF TERMS USED IN THIS REPORT
1. Yield. Yields of grain sorghum are reported as bushels
per acre of threshed grain at 13.0 percent moisture and ·
56 pounds per bushel. Adjustments are made for signif-
icant variations in stand.
2. Moisture. Grain was dried to a uniform moisture content.
3. Height. The distance from the base of the plant to the
top of the plant is reported in inches.
4. Lodging. Plants leaning at an angle of more than 30 ·
degrees from the vertical are considered lodged. ‘
5. L.S.D. The abbreviation "L.s.d." means least significant
difference. Two varieties differing in yield by less than
the L.s.d. cannot be said to differ in yield in that par-
ticular test if one wishes to be correct at least 95
percent of the time.
6. Head Type. Plants with the most open heads are given a
rating of 1 and those with the most compact heads a
rating of 5.
