Exactrix owner, John Yockey of Aurora, Nebraska is a pioneer
in Relay Intercrop. You can learn more about John Yockey at

Dark Northern Spring
Wheat....high protein, high quality wheat with a much better
market price than HRWW.
In year 2004, pictures included, John
raised DNSW (Dark Northern Spring Wheat) in a double-crop
relay with Roundup Ready (RR) soybeans. The DNSW was seeded
into 2003 corn residue in March of 2004. The DNSW yields
were in the 100 plus bushel range using rod row samples
to estimate yield. However, Fusarium Head Blight (FHB) in
the DNSW greatly reduced the final yield and quality. The
DNSW variety was Express. Yields dropped to 60 to 70 bushel
range at harvest due to FHB or head scab and the final
cleanout to remove the infested kernels further reduced the
overall yield. The soybean yields were more than acceptable
in the double crop relay with DNSW. The soybeans were
planted into the DNSW Express about May 15 to 25 of 2004.
Corn is the host to FHB. During 2005 the DNSW was not a good
crop due to field flooding.
Mustard reviewed in the relay
Intercrop technique.
John also raised 40 acres of fumigant
mustard, Pacific Gold, an Oriental mustard variety from
Genesee Idaho, in a double crop relay with RR soybeans. The
remaining 40 acres of the 80 acre ridge till center pivot
was in RR soybeans with no intercrop technique.
As a quick review..... fumigant
mustard is primarily grown for export and shipped to the
Pacific Rim markets. The Pacific Gold mustard was bred
specifically at the University of Idaho for the Oriental
market to be exported as a high quality seed. Oriental
cooking requires mustard oil to produce the definitive hot
and tasty "twang" of prepared food dishes.
The U of I variety is very high in
glucocyanlate. The chemistry forms Thiocyanlate in soil
which acts as a soil fumigant. In fact the soil chemistry
and reaction is very similar to Methyl Bromide, a well known
commercial soil fumigant that is being phased out because of
the ozone layer problem. Oil of Mustard is registered with
the EPA as an insecticide, fungicide, nematicide and may
also function as a herbicide.
John had two primary goals in the
relay intercrop technique using mustard. Profit potential
was great.
Goal 1 was to raise a high quality
seed crop for export using center pivots to boost yields and
allow the RR soybeans to be seeded in the relay. High
quality Oriental Mustard seed can reach lofty prices...20
cents to 35 cents per pound in the past. The market is very
thin since it has primarily export potential and there are
not a lot of acres or producers.
Goal 2 was to increase the following
2005 corn yields with the fumigation aspect of Pacific Gold
Oriental Mustard.
Goal 1 was not achieved. The
mustard yields were in the range of 2,300 pound per acre.
Highest irrigated yields are in the 3,000 per acre range on
narrow rows in Alberta. The quality of the mustard seed was
poor due to the high humidity at pod fill. So the export
market was ruled out when John submitted the seed for a
quality review at Genesee, Idaho. However, Mustard is an
excellent bio-fuel when properly crushed and processed. In
fact mustard is considered a superior Bio-Diesel...primarily
due to the excellent lubricity and the combustion quality
produces very low emissions as compared to soybean based,
Bio-Diesel.
You may not know this....Yellowstone
National Park diesel vehicles run on U of I processed
mustard oil.
Goal 1 may actually be exceeded
over time. Allowing for some fine tuning John is
planning on crushing the oil and saving the meal. The oil
may be more valuable as a fumigant than as a bio-diesel. The
meal is where the real money is at. The meal can be used as
an organic based soil fumigant for gardens...In fact slugs
can be controlled with mustard meal from the Ida Gold
insecticide variety. So you may be able to buy fumigant
mustard meal for your garden in Nebraska....all John needs
is a small bagging line set up.....a few marketing
skills....and gardeners can begin to see real results with
organic fumigant mustard in their gardens, bluegrass lawns,
trees and shrubs. The Pacific Gold meal has high fumigant
qualities...meeting the needs of gardeners as a safe organic
tool to improve gardens and lawns. The fumigant meal should
retail for about $5.00 to $10.00 per pound in small 5 pound
bags. 20 and 50 pound bags at $2.00 per pound.
John has 95,000 pounds of Pacific
Gold stored in old crib elevator...insects are not a
problem....so the seed will keep. If you want to clean up a
grain bin... filled it with mustard. There will no insects
and mustard will fumigate the bin.
John may be able to break into a new
emerging market for the oil and for the meal. Forty acres of
mustard might bring another $150,000 of gross
income....given a little time. It could be a great sideline
project for his two sons, Tom and Dan. John is a pretty
smart producer with great people skills. Still water runs
deep......and John may have a venture that would match his
busy crop production schedule.
Goal 2 was achieved. The final
report is now in on the 2005 commercial corn crop following
fumigant mustard, Pacific Gold in the RR soybean relay. The
fumigant mustard worked as preached by the University of
Idaho breeder, Jack Brown. In large 40 acre test plots laid
out with Auto Farm Guidance John discovered that the corn
yields were 10 bushels higher as he compared to his standard
soybean rotation, corn. He cut the two, 40 acre fields as
one and every time the combine crossed into the mustard
ground the yields jumped 10 bushels per acre. This is not
a real scientific study but enough to convince John that
something is going on with fumigant Pacific Gold mustard in
the rotation. Also yields were the highest yet achieved on
this pivot.
This is a major breakthrough for
corn producers in the very short, yield robbing rotation, of
soybeans and corn. The short rotation is limiting yields
and the Relay Intercrop technique using fumigant Pacific
Gold Mustard may have long term benefits that may not be
fully understood for another five years.
What are the management
issues using Pacific Gold mustard in the Relay Intercrop
Technique?
1. The seeding tool and seed delivery
must be precise....the modified Deere 1590 or 750 drill was
used with great success. Do not consider air cart seed
delivery since the metering is not as good with the high
cost seed. Gravity drop or individual air port metering is
best. Fluted feeds, Valmar or Gandy seed delivery is great.
Make sure you No-till seed the crop as early as possible.
2. You need a dual placement,
No-till Exactrix Tool Bar to properly fertilize the
crop...mustard needs lots of sulfur and has nutrient needs
not seen in typical corn production techniques. TAPPS is
great fertilizer package for mustard using single disc
openers on 15 inch band centers....Go to
www.exactrix.com/yockey.htm.
3. The weed control is
trick....especially at Grand Island.
4. Do not try to raise the seed for
export....producing high seed quality is way too risky as
compared to drier climates.
5. Soybeans in the relay need more
light since the mustard is very competitive and will hurt
the soybean yields. Certain soybean varieties may perform
better.
6. Mustard must be harvested earlier
in the Relay.....there is no Roundup Harvest label for
mustard if you plan to export the seed or meet food grade
quality standards. Mustard is not a determinant crop like
wheat. The harvest label is used in the relay if wheat is
selected for the relay. But there is an answer to this
problem.
The management issues are
solvable.
1. The drills are available and can be
modified to do Relay Intercrop.
2. The nutrient application tool bars
are available from Exactrix.
3. The weed control and the maturity
can be controlled with Roundup late in the mustard
propagation season.
4. Do not raise the mustard as a food
grade crop....raise it for the oil as bio-diesel...raise it
for the meal...... and raise mustard to improve the
following corn yields.
5. Arrange the row spacing more open
to allow more light into the soybeans. Mustard might be
best seeded with a 24 inch area open for the soybeans and
allowing two, six inch spaced mustard rows...the spacing
would be 24 inches wide for the bean planting area with a
six inch area reserved for two mustard rows....24/6 on 30
inch ridge till rows.
6. Since food grade mustard is ruled
out, producers can use Roundup to ripen the crop early and
control weeds. Since this is an industrial crop producers
need not be concerned about food grade issues...but make
sure it is always segregated which is probably not a problem
at Aurora/Grand Island, NE. Also the soybeans will see
light sooner if the mustard is killed in late June or early
July. If the weather turns to the wet side the Roundup must
be applied.
What are the possibilities
of Relay Intercrop?
Dr. Jim Schepers USDA-ARS, Lincoln
says that the corn is the problem.....the best economics if
you want to raise RI wheat is the wheat soybean
combination and drop corn entirely....plus most states have
a Folicur label for wheat and above all soybeans may need a
fungicide early for rust. So you can get a double punch out
of Folicur if you time it right. Nebraska is the only wheat
producing state that does not have a Folicur label.
The best economics for producers that
want to raise wheat in the rotation requires that corn be
dropped for now. FHB is not good news with no major
breakthrough coming to control FHB head scab.
Producers should be able to raise 100
plus bushel winter wheat and DNSW followed by 50 to 60
bushel beans....this is the best choice for now....and a
lower level of risk.
Producers can certainly try other
crops in the Relay....RR alfalfa may have a great start in
mustard, HRWW or even DNSW. Maybe millet should follow
mustard and just double crop. Some smart producer is going
to figure this out.....a potential gross return of $700 to
$800 per acre can not be denied.
King Corn, move over....there
are better choices.
Corn producers take note..... of the
potato producers in Washington, Idaho and Oregon....fumigant
mustard has shortened the potato rotation from 4 years to 2
years using mustard as a cover crop following soft white
winter wheat and hard red spring wheat....fumigant mustard
controls nematodes.....this may be a critical factor with
soybean cyst nematode. Use mustard as tool to raise better
crops and better net returns...it has potential.
Fumigant Mustard will provide many
years of value to improve nematode infested soils that will
not respond to other management choices in the corn soybean
rotation.
