very marked, giving a yield of 500
POUNDS OF crab grass per acre.
CONCLUSIONS.
/. Subsoiling on this land does not
phy Tor the extra labor required.
:. 1t is a good practice to apply nj
trate OF soda to corn during the early
stages of growth in view of the extra
growth of grass that it induces This
IS III continuation of an experiment per-
formed on an adjourning section in
1890. In that case the plots manured
with stable manure 5000 per acre( and
chemicals produced no aftergrowth of
grass; while adjacent plots on which
nitrate of soda and cotton seed meal
We're used as ammoniates, instead of
stable manure, gave very luxu1iant
attergrowth, equivalent, probably to
one ton of hay per acre.
INTERCULTURAL FERTILlZING-CORN.
This experiment is repition of SINH
lar experiments made by the station in
1690-91, with but d slight change in the
details The object of the experiment
was to ascertain the benefits to be de-
rived by applying fertilizers during the
growth of the plants The readily
available character of Nitrate of soda
renders it superior to cottonseed meal
as an interculturLl fertilizer. While as
a general ammoniate cottonseed meal
is superior as it remains long in the soil
and not lending out what is not taken
up by the plants one year remains for
subsequent crops.
RESULTS.
A careful study of the table fails to
show any significant difference between
the yields Of plots ON which the fertiliZ-
ers were all applied at one time before
planting and those which received the
same formula in two or more success
slve doses. The average yield of plots
on which the formula containing nj
trate of soda as an ammoniate was APP
piled at one time-before planting
less than five pecks per acre greater than
the average yield of the plots on which
the formula was divided into two and
three doses. But this difference, small
as 1t is, Is not sustained by the results
OF the Internationally fertllized plots
compared with each other. The yields
of the plots on which cottonseed meal
Wos substituted for nitrate of soda is
unexpectedly low as compared with the
nitrate of soda plots Plot 10, on which
che whole was applied at one time,
shows an exceptionally high yield, but
| there is reason to fear that some error
was committed. or there was undiscov-
cred cause for this excess. The aver
age yield of all the cottonseed meal
plots, however, was nearly two bushels
less than the average yield Of the nitrate
of soda plots.
CONCLUSIONS.
The results correspond substantially
with those OF similar experiments made
IN 1895 and 1891, hence we conclude:
l. There Is no material advantage to
the current growing crop Of corn in
dividing the fertilizer into two or more
doses to be applied successfully during
the growing period
y This experiment indicates that for
corn nitrate of soda is a somewhat bet
ter form of nitrogen than cottonseed
meal.
DEEP VS.. SHALLOW CCLTURE-CoRN.
The object of this experiment was to
find If there is any advantage or loss in
cultivating corn deeply. A number
OF experiments of similar nature have
been conclued at the station and they
all confirm the conclusion that after
thorough preparation no advantage is
to be obtained by deep culture, the
shallow culture plots yielding more
fodder III most experiments. In the last
experiment there was an increase of
O.29 of bushel in deep culture plots
which did not pay for the extra blowing

As has been remarked in commenting
on variety tests of corn i'll previous
years, such tests are by no means con-
elusive to which OF several varieties is
the best.
Such tests can only compare the rela-
tive DrOductiveness of such varieties as
are very similar. if not identical, in
their habits OF growth and ssperiods of
fruiting. AS between two kinds of
corn, one of which silks and tassels sew
eral weeks in advance of the other, it is
manifest that the seasons may be very
unfavorable for the earlier variety at
the most critical period (silking time),
while the later variety may strike the
seasons" exactly right, and vice versa.
So of two varieties that differ very
much in size of stalk and ears, the dis
lance given to both being the same,
one may have gust the right number of
plants on the land, while the other may
be too thick or too thin. Practical
| farmers understand this,
1t is but fair to say that the nine first
named seemed to be much alike in size
Of stalk and ear but not exactly, while
numbers 10 and II were smaller in stalk
and ear, and little earlier. Hence the
test is not strictly fair to these two,
especially Blount's Prolific, as they
should have been planted closer. Nos.
l, Z, s and 9 seemed most desirable on
the score of yield, uniformity in size of
ears and color of grain and soundness.
