 RESULTS OF THE KENTUCKY GRAIN SORGHUM
PERFORMANCE TESTS -1953 - 1955 ‘
.1. F. Shane, H. R. Richards and Leo A. Link
The tests reported herein were designed for the evaluation
of existing grain sorghum varieties which were developed by
state and federal agencies. Performance records for the varieties
tested are given in Tables 1 ~ 7. The summary for the period
1953-1955 is given in Tables 8 — 9.
EXPERIMENTAL PROCEDURE
Row Spacing was 36 inches in the Lexington test, 42 inches in
the Hopkinsville test, and 21 and 42 inches in the Princeton te st.
Planting rates were 6 to 8 pounds of seed per acre. No stand
counts were made in the Lexington and Hopkinsville tests. Stands
at Princeton are given in Table 6 with other pertinent agronomic data.
Yields are recorded as bushicis per acre of threshed grain at
13.0 percent moisture. Corrections were made for major differences
in stands, but not for minor differences.
Plant height was measured as it is important in relation to com-
bining.
INTERPRETATION OF DATA if
The difference necessary to as sure reasonably that a significant
difference in yield exists between varieties has been calculated and is
given at the foot of each table a s t’¤€ least significant difference
(L. S. D.) . Unless the yields of two varieties being compared differ
by as much as or more than the L. S. D. , little confidence can be
placed in the superiority of one variety over the other in that particu-
lar te st.
Agronomic data other than yield have not been subjected to a
statistical analysis; however, small differences between varieties
should not be considered strongly indicative of a true difference.
