INTRODUCTION

Material progress has been made towards improving the yield of corn
in the past 50 years, but very little work has been reported concerning
moisture content of the grain at harvest time. Both yield and moisture
content are of importance to Michigan farmers. Maximum yields mean a
greater financial return from the crop. Lower moisture content indicates
an earlier maturing corn as well as a better chance for the corn to come
through the winter without molding.

Various cultural practices have been tried in other states in an
attempt to increase the yield of corn. Some of these cultural practices
have proved to be highly successful in some states, while in other states
contradictory results have been reported. The question arises, can cultural
practices increase the yield of corn in.Michigan as well as decrease the
moisture content?

The purpose of this prdblem was to determine whether different times
of plowing and rates of stand have any affect upon the yield and moisture
content of corn and whether different varieties react the same to the above
factors. The times of plowing were fall plowing, Spring plowing and no
plowing. The rates of stand were 3 stalks per hill and 2 stalks per hill.
The varieties included numerous commercial hybrids and experimental single

CI‘OSSBS.

REVIEW OF LITERATURE

Kiesselbach, Anderson and Lyness (8), in a 6-year comparison of seed-
bed preparation practices for corn at the Nebraska Experiment Station,
showed that early spring plowing yielded 12 percent more grain per acre
than late spring plowing and 13 percent more than fall plowing.

Kiesselbach, Anderson and Lyness (9), in an 11-year comparison of
seedbed preparation practices for corn at the Nebraska Experiment Station,
showed that early spring plowing yielded 5 percent more grain per acre
than late spring and 18 percent more than fall plowing.

Foster and Merrill (h) found that seeding 6 kernels per hill gave
9.07 bushels per acre more than 9 kernels per hill and lS.hl bushels more
than 3 kernels while using Common White Flint.

Montgomery (10), using Hogue's Yellow Dent for a 5-year period, found
that corn planted at the rate of 3 stalks per hill averaged 75.5 bushels
per acre, and corn planted 2 stalks per hill averaged 67.7 bushels per acre.

Bull (1) believed that 3 stalks per hill yielded considerably more
than 2 stalks per hill.

Helm.(S), at the Missouri Experiment Station, showed that checked
corn of 2 stalks per hill averaged 2.3 bushels per acre more than the 3
stalk rate over a period of 3 years.

Kiesselbach (7) found the grain yields, over a h-year period with the
planting rates of l, 2, 3, b, and 5 plants per hill, were, respectively,
no.7, h9.h, 52.9, 50.7, and h9.3 bushels per acre. It was felt that a
stand from about 2.5 to 3.0 plants per hill was optimum for the local
varieties grown under the experiment station conditions.

Kiesselbach, Anderson, and Lyness (8) found that the yields of checked

corn, with the hills spaced 3.5 feet apart, having stands of l, 2, 3, b,

-3-
and 5 plants per hill were, respectively, 36.8, h5.h, h8.7, h6.0, and h2.9
bushels per acre over a 12—year period using Hogue's Yellow Dent.

‘Wallace (15) suggested that corn be planted with a stand 3 stalks to
the hill rather than 2 stalks per hill with the hills 3.5 feet by 3.5 feet
apart. He also feels that corn with 2 stalks per hill will yield better
during a dry season.

Kiesselbach, Anderson, and Lyness (9), over a lh-year period with a
stand of l, 2, 3, h, and 5 stalks per hill that were planted 3.5 feet apart,
found that they yielded, respectively, 37.3, h6.5, h6.8, and hh.l bushels
per acre. During an 18-year period with the rates of 2, 3, h, and 5 plants
per hill, they found that the rates produced h3.6, h6.3, h2.8, and hl.6
bushels per acre, respectively.

The Ohio Agricultural Experiment Station (12) says, "For the 21-year
average, a stand of h plants per hill with hills 3.5 feet by 3.5 feet
apart gave the largest yield of shelled corn per acre from both ears and
nubbins with 3 plants leading in poor seasons and 5 plants leading in
good seasons. From sorted ears only, 3 plants gave the largest 21-year
average yield and also for the poor seasons; whereas h plants led for the
good seasons".

Mooers (ll) believes that different varieties require appreciably
different rates of planting. In general, the small and short-seasoned
varieties require a thicker planting than the large, long—seasoned vari-
eties. To approximate the proper stand of corn, a simple equation may be

used, as follows:

N : 56 Y
_F__.

In this equation, N stands for the number of the stalks per acre, Y for

-14..
the expetancy or approximate production in bushels per acre of the field
in question under average seasonal conditions, and F is the standard var
rietal factor, or the average weight of grain per plant at the best rate
of planting, as determined experimentally for the variety in question.

Osborn (13) said that on reasonably fertile land with a favorable
season, corn planted at a rate of 9000 plants per acre would outyield a
6000 rate. Using upon pollinated varieties, he found, over a 5-year
period, that 8 of the varieties tested gave definite increases of over S
bushels as the rate increased from 6000 to 9000 plants per acre; 3 of the
varieties showed increases of 3 to h bushels; with 5 varieties, the 9000
rate yielded within a bushel above or below the 6000 rate; 2 varieties
gave a decrease of l to 2 bushels in the 9000 rate as compared with the
6000 rate; and l variety gave a definite decrease of 5 bushels in the 9000
rate.

The Kentucky Agricultural Experiment Station (6) states, "In determy
ining the proper rate of seeding corn, a good many factors must be taken
into consideration. ‘For example, in comparing the yielding capacity of
corn planted at the rate of 2 plants per hill and 3 plants per hill, experi-
ments have shown that the yield depends largely upon the siée of the plant.
From a large growing variety, such as Boone County White, the largest
yield is very likely to be obtained with 2 stalks per hill, whereas with
the smaller varieties allowing 3 stalks per hill, or its equivalent in
drilled corn, often gives the best results. This year, for example, the
yield among several early varieties tested was strictly in favor of the
3-stalk hill as compared with the 2-stalk hill".

Duncan (3) experimented with h different open pollinated corn varieties

-5-
on h different soil types. He found that large-growing corn varieties
that require a full season to mature will give a maximum yield, if planted
at the rate of 3 kernels per hill. Earlier maturing varieties with smal-
ler stalks and requiring less than a full season to mature, will give its

maximum yield, if planted either 3 or b kernels per hill.

Methods and.Materials

The date on yield and moisture content for this investigation were
collected from corn trials at East Lansing, Michigan, in 19b? and l9h8.

19h? Test:

The crop that preceeded the corn trial in 19h? was alfalfa. This
crop was cut and left in the field that year. A heavy application of
straw was applied to the ground to be plowed down at the designated time.

The preparation of the seedbed for corn planting involved 3 different
times of plowing: (1) fall plowing, (2) spring plowing and (3) no plowing.
The un-plowed ground received the same cultural treatments as did the
ground which was plowed with the exception that the alfalfa was not plowed
under as one of the steps in seedbed preparation.

The area was divided lengthwise into thirds with a time of plowing
being randomly assigned to each third, table 1. Thus, there was no true
replication for time of plowing. Since the different times of plowing
were confounded with location effects, times of plowing will be called
locations hereafter.

Each location area was divided lengthwise into 2 equal strips. Half
of the varieties were assigned to one strip in each location (time of
plowing) and half of the varieties to the other strip in each location.
This gave 6 strips running lengthwise of the field. Each of these 6 strips
were further subdivided in half, lengthwise of the field, giving 6 pairs
of sub-strips. To each pair of sub-strips there were then randomly assigned
the 2 rates of stand - 3 plants per hill and 2 plants per hill, table 1.

The elemental plots in this test were 2 rows wide and 7 hills long

‘with the hills being planted 3.5 feet by 3.5 feet apart and with the long

.3.

way of the plot running across the rate of stand. The various varieties
were planted 5 to 6 kernels per hill and thinned down to the desired rate
of stand before the plants were 18 inches tall.

Forty-one double cross corn varieties were planted in a series of
6.1 6 Latin squares. ‘Five varieties were planted in each square along
with a sixth variety which was common to all squares and was the 'standard*
variety for the experiment. In addition, one row'of this common variety
'was planted between successive squares and is tenmed a ”check", table 1.

0f the 6 "columns" in each Latin square, 1 pair were assigned to
each location (time of plowing). One column of a pair was then randomly
assigned to each of the 2 rates of stand. Thus, within any one Latin
square there were 3 locations and 2 rates within each location.

l9h8 Test:

The crop that preceeded the corn trial in l9h8 was oats, seeded to
alfalfa with the alfalfa being used as a green manure crop.

The general field layout was similar to that of l9h7. The same vari-
ety was again used as check and standard in the entire test. Sixteen of
the double crosses used in 19h? were planted along with 30 other double
crosses and us single crosses. The double crosses were kept together in

9 squares while the single crosses were kept together in 9 other squares.

Analysis:

There were 3 ways in which the data could be analyzed: First, by
use of the checks and standards, which were all planted to the same variety
both yea‘s. As mentioned previously, table 1, h of the 8 squares of 1987
were in 1 set of strips and the other h squares in the other set of strips.
This meant that there were 8 squares side by side lengthwise of the field
and 2 squares partially interwoven crosswise of the field. This arrange-
ment required 5 rows of checks (1 at each end of the area and 3 between
the squares) lengthwise of the field. Only 8 rows of checks were used,

1 row at one end of the field not being included. The h squares, length-
wise of the field, gave rise to h broken rows of standards. Each standard
involved 12 plots across the field. The total number of checks and standards
in 19h? was therefore 8 x 12 or 96.

The second way of analyzing the data.omitted the checks, but it includes
all squares, 8 in 1987 and 18 in 191.8. Table 2 shows the yield data for
one square under field arrangement and varietal arrangement. A partial
analysis of variance is shown because the sums of squares and degrees of
freedom.for varieties, the V'x.Ra.interaction and Error - 2 are additive.
This is necessarily so for the reason that the varieties are different in
the various squares. Under this method of analysis, the test was analyzed
as a unit.

The third way of studying the results involved only such data as came

from the 16 double crosses planted each year.

Data:

The ears from 10 full stand hills were harvested and weighed in the
field. A sample of 10 ears, randomly chosen, were sectioned ( 2) to obtain
a moisture sample. This sample was weighed in grams at once and then
placed in a fast drying oven until a constant moisture had been reached
(approximately 2 percent). The sample was then weighed again, and the
moisture was'determined for each plot. By means of these moisture contents,
the yields of grain in bushels per acre were reduced to the comparative
moisture content of 15.5 percent.

Corrections for missing plots in the Latin squares were made accord-

ing to the formula given by Snedecor (11., p. 2714).

EXPERIMENTAL RESULTS
Yield
Checks and Standards

1987 Data:

The yield data for the checks and standards are given in table 3
and the analysis of variance in table 5. It was found that row differences
were not significant. Location differences existed, but the error tenn
was so large that the F-value was not significant. Differences due to.the
different rates of stand were significant at the 1 percent level. Three
stalks per hill yielded better than 2 stalks per hill.

19148 Data:

The yield data for the checks and standards for 19118 are given in
table I: and the analysis in table 5. The results obtained were somewhat
different from those of the previous year. It was found that row differ-
ences were significant at the 1 percent level. This might indicate that
soil fertility was not the same throughout the field. Location differences
existed, but again the error term was so large that the F-value was not
Significantly different at the 1 percent level, with 3 stalks per hill
yielding more than 2 stalks per hill.

When attempting to combine both years' results, it was found that
homogeneity was lacking when the F-test was used with the Error - 3 mean
a(Ii-Jars variances (11:, p. 289), therefore, both years results could not be
combined.

By casual observation of tables 3 and h, it can be seen that plowings
did not act the same over both years. As mentioned above, due to lack of
replications in plowings, plowing effects were confounded with location
eIl‘l‘fects. Hence, no definite statements can be made that location differ-

anes in yield were due to different times of plowing.

.All Squares

19h? Data:

The yield data on all squares are found in table 6 and the analysis
of variance in table 8. It was found that locations showed significant
differences at the 5 percent level. Rates were again significantly dif-
ferent at the 1 percent level with 3 plants per hill yielding more than
2 plants per hill. Varieties showed a.marked difference fromLeach other,
but that was expected since hl varieties were used. However, it should
be observed that the varieties responded the same to the different rates
of stand. In other words, all the varieties used this year yielded better
at 3 stalks per hill than at 2 stalks per hill.

l9h8 Data:

The yield data on all squares are found in table 7 and the analysis
of variance in table 8. It was found that location differences did exist,
but the error term was so large that the F-value was not significant.
Rates were significant only at the 5 percent level.

The Error - h mean square variances were used to test for homogeneity.
The retest showed the differences between variances to be highly signifi-
cant, consequently, both years' results could not be combined in this
portion of the experiment. I

Common Varieties

19h? Data:

In the over all experiment, 16 double crosses, other than the standard,
were common to both years. The yield data for the common varieties in 19h?
are found in table 9 and the analysis of variance in table 11. It was
found that differences due to locations appeared to exist, but the F-test
was not significant. Rates were significant at the 1 percent level with
3 stalks per hill yielding more than 2 stalks per hill. Varieties were
also significant at the 1 percent level. .As seen in table 10, all 16
varieties yielded better at the rate of 3 stalks per hill.

l9h8 Data:

The yield data for the common varieties in l9h8 are found in table
9 and the analysis of variance in table 11. Differences due to locations
and rates were apparently great, but the error term.used to check them was
so large that the P-value was not significant. An explanation as to why
this error tenm was so large is not available. All 16 varieties reacted
the same to the rates of stand with all varieties yielding more at the
rate of 3 stalks per hill, table 10. This was true for'both years.

The 2 years results could not be combined for the reason that they

were not homogeneous, as tested by the Error - 2 mean square variances.

.15-
Hoisture Content
Checks and Standards

The moisture content data for the checks and standards are given in
table 12 and the analysis of variance in table 1h. It was found that no
significant differences existed between different locations or rates of
stand in 1987. The same was found to be true in 19148, table 11:.

The Error - 3 mean square variances of both years were checked against
each other. The Fhvalue obtained from this test was not significant. It
'was then assumed that homogeneity existed between the checks and standards
over the 2-year period. Under this assumption, it was possible to combine
the results of both years. lhen both years were combined, differences due
to plowing times could'be.measured statistically by using years as repli-
cations.

The analysis of variance for the combined years of 1987 and l9h8 is
found in.table 1h. It was found that differences due to plowings were
significant at the 5 percent level, with fall plowing causing the corn to
have the lowest moisture content, table 15. There were no significant

differences due to rates of stand when the 2 years were combined.

-l6-
All Squares

19h? Data:

The data for this portion of the experiment are found in table 16,
and the analysis of variance is found in table 18. Significant differences
at the 5 percent level existed between locations and at the 1.percent level
between rates. The moisture content of corn with a stand of 3 stalks per
hill was higher than with corn.thinned to the 2 stalk rate, table 16.
Differences due to varieties were highly significant, as were differences
due to squares. However, the latter has no direct bearing on either times
of plowing or rates of stand.

l9h8 Data:

The data for this year are found in table 17 with the analysis of
variance being found in table 18. Differences between double crosses and
single crosses-were rather great, but no comparison can be made for the
reason that the inbreds involved in the angle crosses were not the same
inbreds that were in the double crosses. It can be seen, table 18, that
the mean squares for the single crosses were considerably smaller than
for the double crosses. This might indicate that the single crosses were
more uniform in their moisture content.

There were no significant differences between locations or rates of
stand, but the error term used to test these differences was so large
that the F—value was not significant.

Both years:

The Error - h mean square variances of both years were not significant-
1y different from each other as tested by the F-test. Therefore, it was
possible to combine both years results. lhen these results were combined,
it was found there were no significant differences between times of plowb

ing or rates of stand. Too much stress cannot be placed on this statement

.17..

because of the different varieties that were used in both years. From
table 19, there is an indication that differences due to rate may not be
of material importance, but fall plowing apparently caused the corn to
have a lower moisture content over both years. There was no apparent
significant difference in the way the various varieties reacted to the
different rates of stand.

~18-
Common'Varieties

1987 Data:

The data on the common varieties are given in table 20, while the
analysis is found in table 22. No significant differences existed between
locations or rates even though the error term used to check these differ-
ences was practically negligible. Varieties were significantly different
at the 1 percent level as far as moisture content is concerned, but that
can be expected when 16 different varieties are tested.

19h8 Data:

The data on moisture content for the common varieties in 19h8 are
given in table 20 and the analysis of variance in table 22. Although
there appeared to be some differences in moisture content due to locations
and rates of stand, the error term was so large that the F-values were
not significant. The varieties were again significant at the 1 percent
level.

Both Years:

The Error - 2 mean square variance were homogeneous for the 2 years,
so both years' results could be combined. The analysis of variance for
the combined results is found in table 22. It was found that no significant
differences existed between plowings or rates of stand. There is an indie
cation.that fall plowing gives a.1ower moisture content for‘both years
and that 2 stalks per hill will produce corn with a sanewhat lower moisture
content than the 3 stalk rate. From table 21, it would appear that there
might be some differences in the way that varieties respond to the differ-

ent rates of stand, but it would also appear that it depends on the year.

.19-
Conclusions

Under the conditions of this experiment, it would appear that 3
stalks per hill will yield significantly better than 2 stalks per hill,
but that more data are needed before a definite statement can be made as
to the effect cf time of plowing on the yield of corn.

There is a rather strong indication that varieties will react the
same way to different rates of stand in the production of grain. Under
the conditions of this experiment, varieties tended to yield better at
the rate of 3 stalks per hill than at the 2 stalk rate.

As far as moisture content of the ear is concerned, it would appear
that rates of stand do not materially affect the moisture content. There
is some indication that 3-stalk hills are slightly higher in moisture
content.

There is some indication that fall plowing will cause corn to have
a lower moisture content than will spring plowed or unplowed ground.

In.moisture content, it would appear that there might be some differ-
ences in the way that varieties respond to the different rates of stand,

but it would also appear that it depends on the year.
