HIGH OIL CORN - UPDATED
FOR 2003
Description: High Oil corn has an oil content
of 7.25 to 7.5 percent compared to about 4 percent for normal
corn. The added oil makes this a high-energy feed that can
be used to increase growth performance in livestock or poultry,
or to replace more expensive energy sources in feed rations.
Data from the last seven years has also shown that protein
levels are also higher than conventional yellow corn. Most
of the high oil corn acres were grown with DuPont’s TOPCROSS®
technology, which involves planting seed of a high oil pollinator
mixed with seed of a male-sterile hybrid. High oil corn blends
grown with the TOPCROSS® system often produce yields comparable
to the grain parent, depending upon the growing conditions.
Due to higher grain energy content, though, yields of HOTC
have sometimes been lower than those of normal corn, especially
when yields are limited by the total amount of energy available
from photosynthesis. Some work is also being done to improve
oil content using traditional breeding. A survey of high-oil
corn growers in 2001 reported that high-oil corn yields were
97% of conventional corn, while seed companies report yields
of 95-105% of conventional corn.
Trends in Demand: The interest in producing
high-oil acres continues a downward trend due to uncertainty
with yields and premiums offered. However, there continues
to be a strong export demand for high-oil corn. In 2002 nearly
500,000 acres of high oil corn were grown in the U.S., down
from 900,000 acres in 1998. About 65% of these acres were
grown under contract for the export market for feed use, while
the remaining 35% was grown for domestic livestock feed. Contracted
acres of high-oil corn are grown in southern Minnesota, northern
and eastern Iowa, and central and northern Illinois. In 2003
projections are for 450, 000 acres of high-oil corn to be
grown. Low prices of feed fat, a byproduct of the meat processing
industry, and cooking oil from the fast food industry has
decreased the demand for high-oil corn domestically, even
though high-oil corn offers a more consistent source of energy
in feed rations. Export contracts for 2003 are at a maximum
of 25 cents for 7.5-8% oil, plus there may be an additional
premium paid for early sign up as well as delivery incentives.
Premiums decrease one cent for every tenth of a drop in oil
percentage. Continued growth in demand for high-oil corn can
be expected in the Middle East, Mexico, Latin America and
Japan. Most of the high-oil corn hybrids are non-GMO which
is a benefit for the export market.
RECOMMENDED PRODUCTION MANAGEMENT
PRACTICES
- Seed Selection. Important considerations for successful
high-oil corn production are oil content, yield potential,
maturity, standability, disease resistance, drought tolerance,
dry-down and adaptability. To ensure top yields and maximum
profit, ask your seed dealer about elite hybrids adapted
to your area.
- Field Selection. To maximize returns, select better-yielding,
top-quality soils.
- Crop Rotation. A good soybean-corn rotation plan is recommended
to increase yield and decrease insect and disease pressures.
- Isolation. For best results, plant TOPCROSS? high-oil
corn varieties in large blocks to reduce oil content loss
due to pollen drift from normal hybrids into high-oil fields.
- Seedbed Preparation. Prepare a seedbed that will promote
uniform seed emergence and crop development. Avoid cloddy
soils with heavy residue and poor furrow closure conditions.
Conventional and minimum till methods may provide for more
even plant emergence.
- Plant Population. Increase plant density as much as 10%,
or by 2,000 to 3,000 plants per acre when planting at populations
less than 30,000 seeds/acre to make up for less-productive
pollinator plants. Around 30,000 to 32,000 is ideal for
highly productive soils, with a yield response up to 34,000
under good conditions. Ask your dealer about specific rate
recommendations as per field and hybrid selected.
- Planting Date. Plant early, as you would other hybrids.
The second half of April is normally the best time to plant.
- Fertility. A good balanced fertility program is a must.
Starter fertilizer can promote uniform plant emergence for
good pollination. Nitrogen should be used at a rate of 1.2
pounds per bushel of expected yield, minus 40 pounds nitrogen
if following soybeans, and minus other nitrogen applications
such as manure and DAP.
- Insect Management. In the TOPCROSS? high-oil hybrids,
the pollinator may be more susceptible to insects, therefore,
it is important to have an effective pest control program.
If planting corn on corn, below-ground pests should be controlled
with a soil insecticide. Rootworm insecticide should also
be used in areas where western corn rootworm damage has
been observed in first-year corn or where wireworms and
true white grubs have a history. During the growing season,
monitor fields for aboveground pests such as corn leaf aphid,
corn rootworm beetles, and Japanese beetles that can clip
silks and reduce the number of kernels pollinated.
RECOMMENDED HARVEST AND POST-HARVEST
MANAGEMENT PRACTICES
- Harvesting High-Oil Corn. To avoid excessive mechanical
damage to kernels, make sure the combine is properly adjusted
according to the operator’s manual. Set the clearance and
speed of the cylinder and make slight adjustments as grain
moisture and field conditions change. Grind off all sharp
edges in the feeder housing, rotary and handling systems.
Replace excessively worn augers. Rotary combines are generally
recommended.
- Drying Strategies. Some field drying is good, in that
it lowers drying costs. High-oil corn may be artificially
dried at low temperatures. Temperature must be kept below
110?F during the drying process to minimize undesirable
quality losses. Many producers prefer to transfer corn to
separate storage facilities after drying.
- Corn Handling and Cleaning. Keep high-oil corn separated
at harvest and in storage. Make sure that augers to and
from the dryer are not causing damage: keep augers full
when running and consider replacing pulleys to reduce auger
speed to help maintain grain quality. Clean dry corn before
placing it into a storage bin to improve airflow and reduce
the potential for spoilage problems. Storage bins should
be swept clean prior to placing grain in them to reduce
insect problems. Run a cooling cycle through grain once
a month during the fall and throughout the winter to lower
grain temperature by 10 to 15?F at a time. Cover fan to
minimize moisture accumulation in stored grain during premature
warming in the spring.
SAMPLE PARTIAL BUDGET ANALYSIS1
- Seed Costs:
- High-Oil Corn: 31,000 kernels per acre (increased
6.5% to make up for pollinator) = 2.6 acres per 80,000
kernel unit; $111.25 per unit ÷ 2.6 acres = $42.75
per acre.
- Regular Hybrid Corn: 29,100 kernels per acre = 2.75
acres per 80,000 kernel unit; $96.25 per unit ÷
2.75 acres = $35.00 per acre

- Increased profit potential per acre:
Regular Hybrid Corn: 155 Bu/acre x $2.35
per Bu = $364.25
$364.25 per acre - $199.00 cost per acre = $165.25

Added Value = $ 18.25 per acre
High-Oil Corn with equal yield: 155 Bu/acre

- Trucking Costs:
Semi - $2.00 per loaded mile. Trucking costs may be higher
if high-oil corn must be transported further.

1 This analysis provides
an example, based on statewide production costs, how farmers
can evaluate the economics of high-oil corn. Producers should
use their own cost and yield data in comparing the potential
profitability of HOC under local conditions.
2Based on experienced farmer
interviews, first time producers should anticipate an average
yield reduction of 5% less than their normal yields. A 3%
yield reduction has been assumed in this example to compute
the additional value/acre of HOC.
3Some experienced producers report
that HOTC hybrids yield as well as their normal hybrids. In
these cases, HOC can produce extra profits, as shown in this
example.
4This is the average premium
for 7 firms responding to Illinois Specialty Handler Survey,
ranging from 15 to 27 ¢/Bu.
