EVALUATION OF CORN HYBRIDS IN ALABAMA, 1994

INTRODUCTION
Selected varieties of corn hybrids are evaluated annually by the Alabama Agricultural
Experiment Station as a service to producers and industry. These tests are spread throughout
the State in an attempt to determine effects of different climatic factors and soil types on
yield. There are several types of tests in the program. The Preliminary Hybrid Tests are
conducted at one location in each of the northern, central and southern regions of the State.
These tests include experimental and newly released hybrids. If a hybrid is outstanding in the
preliminary test it is entered in the Regular Corn Hybrid Test in the following year.
The Regular Corn Hybrid Test is conducted at three locations in the northern region,
three locations in the central region and four locations in the southern region. Early yellow
corn hybrids are tested at one location in each region. A white corn hybrid test is conducted
at Crossville in northern Alabama. In addition, one regular corn hybrid test is irrigated at
Headland in southern Alabama. Locations and cultural practices for all tests are shown in
Table 1.
PROCEDURE
All tests are laid out in a randomized complete block design with four replicate plots
for each variety at each location. Rows were 30 to 36 inches apart, depending on location.
Two-row plots are used, and both rows are harvested. Plots are 20 to 30 feet long, depending
on location. The target plant population for the tests is 20,000 plants per acre with a seeding

rate of 23,000 seeds per acre. The irrigated tests at Headland are seeded at a rate to achieve
30,000 plants per acre, but are thinned to 25,000 plants per acre.
Grain yields are adjusted to 15.5 percent moisture and converted to bushels (56 lb) per
acre. Stalks broken or leaning more than 45 degrees are considered lodged. The mid-silk
data show the number of days from planting until approximately half the plants in the plots
are showing silks. The Regular Corn Hybrid tests also are examined for disease incidence at
selected locations each year. When virus or other disease symptoms indicate crop damage,
disease ratings are compiled and published in this report. However, in 1994, no disease
ratings were taken.
INTERPRETATION OF DATA
In replicated experiments such as those reported here, yields from each of the four
replicate plots of a particular variety at a given location will be slightly different, because of
inherent differences in productivity among those plots. These differences in yield among
replicate plots are known as random variation. Given this situation it is clearly necessary to
have a method to determine whether differences among hybrids are "true" or "real"
differences, or whether they are due to random variation. To do this a statistical analysis is
conducted to determine a "least significant difference" (LSD) by comparing the differences
among varieties with random variation. If the difference in yield between two hybrids is
larger than the LSD, then the difference is probably real, but if the difference is less than the
LSD, it may not be real. If the difference between two hybrids is less than, but close to the
LSD, then there is still a chance that it is real, but if it is considerably smaller than the LSD,
then it is probably not real and mainly due to random variation.
With this in mind it is very important to study differences in hybrid yields in relation
to the LSD which is provided at the bottom of the table for each of the current year yield
-2-
columns at each location. Clearly, LSD's vary from one location to another. This is because
random variation varies among locations and from year to year. The coefficient of variation
(CV) is a reflection of random variation, and is reported below the LSD values in the tables.
If the CV is low a precise or reliable test is indicated. Ideally, the CV should be below 10
percent, but CV's of 10 to 20 percent are acceptable. Values for the CV above 20 percent
indicate a rather unreliable test, which may have been caused by factors such as disease
variation among replicates, etc.
In comparing yield potential of two hybrids it is important to consider a wide range of
results. Do not focus on results from only one year at one location. Two- and three-year
average yields are provided by location and region. These are more useful guides than yields
from only one year. However, other factors may deserve consideration. For example, the
differences between the highest and the lowest yield of a hybrid across several locations may
be an indication of the stability of its yield under variable conditions, or what the "risk level"
of the variety is.
Differences in yield of hybrids among locations will be a result of the combined
effects of differences among locations in soil, weather (mainly rainfall), planting date, weed
control, and other factors. To assist in estimating which factors most likely had the greatest
effect on yield differences among locations, planting dates and cultural practices (Table 1),
rainfall records (Table 17) and soil types (Table 18) are provided. This information also
serves as a guide for assessing conditions to which results may be extrapolated.
