were poor,
Diseases, insects, and other pests
Hybrids grown at one of the Centre County locations were inocu
lated with the fungi causing northern leaf blight (NLB) and northern
leaf spot (NLS), but only NLS ratings were made. These are given
in Tables I and 2. The incidence of this disease was not significant
enough to rate at the other locations; however, some gray leaf spot
and bacterial leaf blight were observed at most locations, but did
not cause any significant damage. Also, some stalk and ear rot were
noted
Animal and bird damages were observed but did not cause a
significant problem.
Interpretation of results
Least significant differences (LSD) is the tool used to determine if
two average values are actually different statistically. The differ
ence between two hybrids must exceed the LSD value to be
considered significantly different. Example for yield; LSD = 8.1
Bu/A; Hybrid X = 120.0 Bu/A; Hybrid Y = 105.0 Bu/A; 120.0 -
105 = 15.0 Bu/A difference. Since the difference between Hybrid X
and Y (15.0 Bu/A), exceeded the LSD (8.1 Bu/A), hybrid X was
higher yielding due to hybrid superiority and not simply as a result
of uncontrolled environmental factors.
Cooperators and locations
Early medium-season hybrids were evaluated with the cooperation
of the following persons: Martin Smith, Luzerne County; Curt
Rakestraw, Lycoming County; Don Fretts, Westmoreland County;
Harold Foertsch, Butler County; and university farms, Centre
County.
