PIG and SOW CASTLE p
Now, at far less than you'd pay for an ordinary structure,
you can give your pigs the royal treatment they survive and
thrive on The new STARCRAFT Pig Castle gets your pigs
indoors under controlled conditions where you can save
more of them and also save feed and labor by getting
them to market faster
The STARCRAFT Pig Castle can easily pay for itself in
saved pigs, saved labor and saved feed
And what you get in the bargain is a big boost in your
morale Because while you're improving your pigs' living
environment, you're also improving your own working
environment
Your STARCRAFT Pig Castle nursery building will be
delivered to you ready to use When it's delivered by flat-bed
truck it's placed in any convenient location you choose All
you do is provide a crushed rock base, or preferably a 4-mch

Drought R
Delaware’s 1974 corn yield
was only 12,416,000 bushels -
some three million less than
It should have been.
The drastic effects of last
summer's drought underline
what growers and
agronomists have known all
along-thc major problem in
corn production on the
Dclmarva peninsula isn't
disease or insects, but
moisture stress at critical
periods during the growing
season.
People are looking at a
number of solutions to the
problem. Some arc
suggesting weather
modification as an answer.
Others look to irrigation as
the cure. Many feel this
would be the best and safest
way to meet the need for
water, but only a few
growers have irrigation now,
and for one reason or
another a large percent of
corn farmers aren’t likely to
get irrigation systems for
themselves in the near
future.
This leaves two other
solutions-the modification of
cultivation techniques and
the development of com
hybrids that are drought
tolerant.
University of Delaware
plant geneticist, Dr. Sue
Sullivan, wants to see what
can be done to modify
existing corn hybrids to
hiake them more tolerant of
the frequent drought con
ditions of lower Delaware.
“Most of our hybrids are a
result of research and
development in mid-western

down thru the pit, and out, for virtually odor-free conditions),

full insulation, and lots of other features

Delaware’s Agricultural growers
Experiment Station farm in
Georgetown. The first thing
she will be looking for are the
factors in corn plants that
contribute to drought
tolerance.
These factors include fast
developing, deep-growing
root systems better able to
extract moisture from the
soil and the ability of some
plants to use water more
efficiently-possibly by
closing leaf pores (stomata)
in stress conditions so that
they lose less water mto the
air. Some hybrids have
multiple-ear tendencies,
others will produce larger
ears at lower plant
populations-other important
factors. Since the corn
plant’s need for water is
greatest around silking tune,
the geneticist will also be
looking for plants which silk
well under moisture stress.
