Between The Row?
foolproof, however, and take
some management to calibrate
and use effectively.
Some sources indicate that
for field length measurements,
the accuracy of yield estimates
is often in the 1-2 percent range.
Accuracy falls off somewhat in
short length measurements
because of variations in grain
flow, unifoimity of the crop,
and speed of the combine, so
we need to consider this in
interpreting the yield estimates
that are being produced every
one to three seconds in the cab.
Nevertheless, most agro
nomists arfe viewing yield
monitors as a powerful tool that
will increase our ability to eva
luate management decisions
under fields conditions. This
will help many growers make
decisions more on how the crop
yielded rather than
how it looked in the
field.
The two impress
ions of the crop are
often quite different.
Yield monitors will
also influence how we
do research and will
likely allow us to
make more powerful
measurements which
will increase our abil
ity to detect yield dif
ferences on our vari
able soils in the
Northeast.
Most yield moni
tors can be combined
with a Global Posi
tioning System (GPS)
’civer that supplies
a location coordinate
to the yield monitor.
" his is recorded along
/ ;, h the yield and
crop moisture infor
mation on a computer
data card that can be
removed and read
with a PC. Computer
software is available
to generate yield
maps. These maps
can then be used to
identify low yielding
or problem areas in
the field.
Many agronomists
are working to deve
lop better ways to
interpret these yield
maps by relating yield
to soil fertility, tex
ture drainage, and
organic matter varia
tions in the field.
Another new tech
nology that has
exploded during the
last year has been the
World Wide Web
(WWW). The World
Wide Web is a worl
dwide computer net
work that links indivi
duals, businesses,
universities, and gov
ernment agencies
together. Individuals
or institutions can cre
ate what is called
home pages, which
are basically one to
several “pages” of
(Continued from Pag* 1)
information describing what
they are all about. Each page
often contains many links that
you can click on and go to
another page for more
information.
What does all this have to do
with com growers? It provides
us access to a tremendous
amount of information that was
not at our fingertips readily
before. In a few minutes at my
PC at home I can review weath
er forecasts, read agronomic
newsletter articles from several
universities, download some
pictures for presentations, look
at hybrid testing information
from other universities, and
check commodity prices.
In the past few months there
has been a real proliferation of

With IMF from Mycogen Plant Sciences,
there's more to love than just tall corn.
The 1994 introduction of Mycogen’s
first TMF corn hybrids, developed
exclusively for silage, attracted a lot of
attention. Com plants which stand 12 -13
feet tall with very wide leaves and huge
ears will tend to do that.
But TMF is more than just tall corn. It’s a
system that helps you plan your cropping pro
gram to produce as much of the nutrients as pos
sible for your dairy herd or beef animals. That’s why
Mycogen calls it Totally Managed Feedstuffs™ or TMF.
Mycogen’s TMF silage hybrids, for example, were
bfed not only for extra tonnage but for a higher percent
age of digestible nutrients, such as protein and sugars.
Likewise, TMF Generation alfalfa can produce extremely
high RFVs even with its exceptional disease resistance and
quick recovery after cutting.
