Performance of Corn Varieties in Alabama, 1973
David H. Teem
1
'
Corn performance tests were conducted at 12 locations by the Auburn
University Agricultural Experiment Station in 1973. These tests are
conducted annually to determine relative production of many varieties
offered for sale and to furnish unbiased information by which growers may
choose a variety. They are conducted to give a comparison of varieties
entered in each test and are not intended for use as an absolute measure
of the yielding potential of a variety in an area. Careful consideration
should be given to all performance characteristics when choosing a variety
since the proper choice may mean the difference between profit and loss.
Corn yields in most areas of Alabama were above average in 1973.
Yields of more than 100 bushels per acre were obtained in 9 out of the 12
tests. With one exception, disease incidence was generally low at most
locations. Leaf rust occurred throughout the Gulf Coast region and all
varieties planted at the Gulf Coast Substation were susceptible to the
disease; however, yields in this test did not appear to be appreciably
affected.
In side-by-side irrigated and unirrigated tests at Camden, irrigation
resulted in a large increase in yield. This test was not intended to
show maximum production with irrigation. Plant population, fertilization
and other factors were the same for both tests. The important result was
that the relative yield of varieties was not the same irrigated as un-
irrigated. Higher plant population and fertilization would likely result
in a greater response to irrigation. As a supplement to rainfall this
test received 1 inch of water June 19, July 2, July 6, and July 13.
1/ Research Associate, Department of Agronomy and Soils.
Location of the tests 
and cultural practices 
used are shown in Table
1. Lime and fertilizer were applied in adequate amounts. For 
weed con-
trol either chemical, mechanical, or a combination were used as needed.
The experimental design was a randomized complete block with four repli-
cations. Yields were adjusted to 15.5 per cent moisture 
and 56 pounds per
bushel. Stalks broken below the ear or leaning more than 45 degrees were
considered lodged. Ear rot, earworm damage, size of ear and grain, and
luster of grain were considered in rating ear and grain quality. Height
of ears was measured from ear base to the ground level. Husks were rated
by tightness and extension beyond the tip of the ear.
Regional averages for 3, 2, and 1 years in northern Alabama are pre-
sented in Tables 2, 3, and 4, respectively. Table 5 shows yields by
location and regional average yields for 1-5 years in northern Alabama.
Similar data are shown for central Alabama in Tables 6-9 and for southern
Alabama in Tables 10-13. Results of irrigated and unirrigated tests at
Camden are shown in Table 14. Results from preliminary tests are shown in
Tables 15-17. If a hybrid is outstanding in these preliminary tests it is
advanced to the regular testing program the following year.
When comparing hybrids, small differences in yield may not be real
differences between hybrids but differences resulting from variation in
the plots and testing procedures. To aid in determining real differences
between hybrids a statistical procedure, analysis of variance, was per-
formed on data from each location. The L.S.D. (least significant dif-
ference) is given for yield at each location. This means that if the
difference between two hybrids being compared is greater than the L.S.D.
value, the difference is considered real at the (.05) level of probability.
Long term averages are more reliable when choosing a hybrid. Three
years testing is considered sufficient to give a good measure of the
3
performance of varieties. A rating system was used to determine the list
of acceptable hybrids. The regional average yield of a variety was used
as its base point. The composite rating was obtained by subtracting
values for lodging, quality, and height of ears from its yield. The value
subtracted for each characteristic was proportional to the numerical value
shown for the characteristic in Tables 2, 6, and 10. Although those
hybrids that have a good record for 2 years in the regular test are in-
eluded, and noted, on the acceptable list; preferably, data from more than
3 years are used in evaluating the varieties.
All of the acceptable varieties are not equal in performance. Some
are outstanding in one or more characteristics. Others are not outstand-
ing in any one characteristic, but possess a satisfactory combination of
characteristics. For these reasons, it is suggested that this reprt be
carefully studied before choosing, a variety of corn to lant in 1974.
