ably the more important. We have
already learned how the plant obtains
ftod and water from the soil. The
first step in preparing the soil for
.orn crop, then. is to see that there is
a plentiful supply of plant food on
hand. This we can do by using barn
yard manure literally and by follow
ing consistent system of rotation
that will equalize the demands made
on the soil and keep up the supply of
nitrogen and humus.
The next point is to see that the soil
is in such condition that the roots
will have little difficulty in branching
out to secure the needed plant food
and water. Thorough blowing, disk
ing and narrowing will make the soil
fine and mellow, so that the roots
will have little trouble in obtaining
all the plant food they can use. pro-
vided it Is there at all.
The water supply can be regulated
to considerable extent by tile drain
age and by keeping the surface loose
to check evaporation. The tempera-
ture of the soil is also an important
factor in Fastening termination and
early growth. Drainage, cultivation
and the maintenance of plentiful
supply of humus will aid greatly in
securing warm seed bed by planting
time.
With a warm, well prepared soil
containing sufficient quantities of
plant food and water the next ques-
ton that comes up is regarding the
kind of seed to put into that soil. AL
produce a fair crop under favorable
conditions. What we are after, how
ever, is not fair crop, but an extra
good one.
The seed of.different strains of corn
varies greatly in its ability to produce
yields. In the spring Of 1905 the Iowa
experiment station gathered seed from
nearly hundred different sources and
planted it on the station grounds. I'm
der conditions that were as nearly
alike as it was possible to make them
the yields from the different strains
varied from thirty-one to eighty bush
els per acre. This variation shows
that large share of the Improvement
in corn production must come through
the breeding of high yielding strains.
1t is not safe to ship in seed corn
from distance. Corn Is very sensi
tive to changes in climate and soil. Tc
obtain the best results the work OF
breeding must be done for each local
ity and to some extent for each farm.
A method of improving seed corr
that will surely result in some i'm
provement and one that has simplicity
to recommend it is that of selecting c
number of the best ears each year an(
planting them in a field by themselves

ed. The weak point in this plan, how
ever, is that the yielding power Of al
ear cannot be told from its appear

inbreeding by such method.
To avoid these difficulties the "indi
vidual ear" plot has been devised. Thi
