NC+ Introduces 1993
LINCOLN, Neb. NC+
Hybrids has introduced six new
corn hybrids and three new soy
bean varieties for the 1993 grow
ing season.
The company conducts exten
sive tests on all products prior to
release. Each product released
exhibited superior characteristics
during breeding and research
trials, according to NC+ Hybrids
President Gary Duncan.
“Thi six new com hybrids for
1993 are the strongest group

WASHINGTON. D.C. U.S.
soybean fanners are calling on the
U.S. Trade Representative to
move swiftly to implement trade
retaliation if the European Com
munity does not present a satisfac
tory settlement offer by their mid-
August deadline in the ongoing
U.S./EC oilseeds trade dispute.
In comments submitted to the
Office of the U.S. Trade Repre
sentative, the American Soybean
Association and the U.S. should
“target retaliation against EC pro
ducts from nations most opposed
to a fair settlement which provides
redress to the injured party, the
U.S. soybean farmer.”
ASA first filed a Section 301
Unfair Trade Petition against the
EC in 1987, charging that the EC
has nullified and impaired its 1962
duty-free commitment for soy
beans and soybean meal by offer
ing lucrative subsidies to growers
and processors of EC origin oil
seeds at the expense of U.S. soy
bean exports.
A General Agreement on Tar
iffs and Trade Dispute Settlement
Panel has twice ruled in favor of
the U.S. position. Despite numer
ous promises, the EC has yet to of
fer a meaningful solution to the
problem, according to ASA.

standards.”
NC+’s new corn releases
include four yellow dent hybrids
and two white com hybrids.
The six new corn hybrids
include:
• NC+ 1991: A 99-day hybrid
with excellent yield potential and
fast drydown. Good early color
and growth turn into a strong stalk
with large ears.
• NC+.2844: A 104-day hybrid
with excellent slay-green and
rapid drydown. Girthy ears with
Farmers
ASA contends that EC oilseed
production, as a result of lucrative
subsidies, increased 550 percent
from 1980 to 1991 or by 11 mil
lion acres. At the same time, U.S.
export volume to the EC fell 70
percent (15.1 million acres worth
of soybean and soybean meal ex
ports) while total U.S. soybean
acreage fell 13.5 million acres.
ASA says U.S. export losses to
the EC were “responsible, in large
part, for the dramatic acreage de
cline suffered by U.S. soybean
farmers in the 1980 s.” ASA esti
mates annual economic losses to
U.S. soybean growers from the
EC oilseed regime exceed $2 bil
lion.
“ASA’s intent is not to damage
another U.S. industry or economic
segment through this trade dis
pute,” ASA says in their com
ments. “U.S. soybean farmers
simply seek the opportunity for
their crop to compete fairly in the
EC market.”
ASA reiterates in their com
ments that the 301 is a “litmus
case for the future of GATT. If the
U.S. cannot achieve its rights and
gain reform in GATT-illegal oil
seed subsidies under existing
GATT agreements, of what value
is a new GATT agreement?”

second room, we used a humidistat
to raise or lower the curtain.
The idea behind the humidistat
is that as ventilation rate drops,
humidity level goes up (along with
dust, gases, and bacteria). In a ther
mostatically controlled system, the
set point on the thermostat (65
degrees, for example) mas never
be reached during cold weather.
As a result, the curtain stays shut,
and air quality suffers.
In each of the three trials, the
thermostat room was set at 65
degrees. The humidistat room was
set on 55-60 percent relative
humidity. If the moisture level
exceeded this setting, the curtain
would open, and vice-versa.
Based on daily carbon dioxide
and actual humidity measure
ments, the humidistat was effec
tive at improving air quality in all
three trials.
Hog performance and respirat
ory health, however, were a diffe
rent story. The combined results
from all three trials are listed
below.

In the second and third trial,

Summary

money perhaps more than any
other single group of diseases.

2. Common sense and eve
some research tells us thatrespirat
ory disease is related to air quality
The puzzling issue is why pj«
don’t respond more dramatical
to improvement in air qua iJ
under controlled experimentation
3. Air quality will continue to he
an issue for the next several
decades in our industry, and the
result will be a better environment
That will be good for the hogs but
it will probably be even better f or
the people that work there.
