As a supervisor, your integrity and attention to detail
will contribute to the success of this year's Contest.
This learning tool will help you perform your duties
as a National Corn Yield Contest supervisor.
Over the years the contest has been recognized for its integrity and
credibility which is due in large part to
the network of local supervisors (you) who verify the accuracy
of yields submitted for competition.
Be sure that you are qualified
as a supervisor according to the definitions
found in the box at the top of
page five in the Harvest Rules.

* Questions or concerns regarding your position qualifications, contact NCGA: 636-733-9004
Carefully and legibly fill out all areas of the Harvest Form
Get all required signatures
The Entrant, Supervisor or interested party must mail the completed form and all weight tickets to the NCGA office the earlier of
seven days of the final yield check
or
postmarked by December 1, 2011.
Be sure that you are familiar with Section 1 of the Harvest Rules.
The contest area may be any shape, but it must be 10 continuous acres of the same Hybrid Brand and Hybrid Number.
Be sure to verify the row lengths being harvested.
If a yield check results in less than 250.0000 bushel per
acre, NO recheck is required.
An initial yield check of 250.0000 bushels per acre
or more requires a recheck and two qualified
supervisors must be present for this recheck.
*Re-check may be conducted with the initial supervisor AND another NCGA approved supervisor or two new NCGA approved supervisors.
If the resulting yield is 300 or
more bushels per acre a recheck
is required with two NCGA assigned supervisors
*You must contact NCGA for assigned supervisors. NCGA may assign the
supervisor of the first check and one additional or assign two new supervisors.*

The Supervisor(s) must have the entrant run the combine and the transfer auger empty to make certain no corn has been left in it by mistake. All wagons or trucks must be checked to make certain they are empty.
All end rows/turning rows and the equal number of outermost rows on each side of the field may not be a part of the contest plot.
Harvesting
Transporting
Weighing
Moisture testing
The supervisors are responsible for overseeing all computations and field measurements.
The plot being harvested must be measured to determine its area, and all measurements must be made with one of the following:
Tape
Chain
Measuring wheel
GPS systems ARE NOT accepted as a measuring device
The measuring wheel can only be used when walking-it. Maintain good contact with the ground and avoid wheel skips.
If possible, measure a distance with the wheel, and then check it with a tape to ensure that the wheel is accurate.
Row lengths and row widths must be measured, recorded, and verified in accordance to the Harvest Rules.
Harvest one pass across the field
Then skip three times the amount of rows harvested
Harvest another pass until the required 1.25 or
more acres have been harvested.
Example:
Four-row harvester Harvest four rows, skip twelve, harvest four, skip twelve, and so on
Six-row harvester Harvest six rows, skip eighteen, harvest six, skip eighteen, and so on
Eight-row harvester Harvest eight rows, skip twenty-four, harvest eight, skip twenty-four, and so on
Row length
Row width (spacing between planter rows)
Number of rows harvested in one header pass
Square feet in one acre (43,560)
Moisture Percentage
*Remember to harvest enough total rows to meet the required minimum acreage of 1.25*
The Harvest Form provides the calculations that must be used to arrive at the harvest yield, carried out to four decimal places.
Follow the formulas very carefully and recheck your answers to ensure accuracy.
Run the corn sample through the moisture tester three different times.
Re-calibrate the moisture tester between each sampling.
Average the three moisture samples for a final moisture percentage
*Moisture samples can either be listed on the harvest form or provided with the scale ticket attached to the harvest form.*
After the required 1.25 acres or more have been harvested, and if
the first yield check is 250 bushels or more per acre.
The yield must be verified by a recheck of 1.25 acres or more using
the initial harvest pattern in the rows next to the first
check passes. Only If…
One supervisor is present- Recheck required for all yields over 250.0000 bushels/acre
Two supervisors are present-No Recheck required unless the yield is over 300.0000 bushels/acre
*Over 300.0000 bushels also requires a call to the NCGA office*
Both the first check and the recheck forms and weight tickets must be sent to the NCGA office.
Develop a harvest plan with the entrant to prevent actions that may result in possible disqualification.
Be observant of what is being done.
Ask for clarifications to make sure you understand all harvest activities taking place.
When possible, take the field measurements prior to harvest.
All end rows/turning rows and the equal number of outermost rows on each side of the field can not be a part of the harvested area.
Supervisors must inspect the field conditions to determine if tillage practices meet class qualifications.
As the supervisor, you must remain with the wagons
and/or trucks that will transport the crop at all
times and keep them in sight.
Make sure that the equipment you start the harvest
check with is the same equipment you finish with.
***Remember all weigh wagons are prohibited.***
Grain must be weighed on state certified approved scale.
All wagons and trucks must be inspected by you.
Inspect them on the first check and the second check.
Visually check to make sure the hopper and auger are empty.
Have the operator run the machines to ensure they are empty.
Before the harvest sample is weighed, certify that a
state-inspected scale with current inspection
stickers attached will be used.
Every time the grain is weighed, you as the supervisor,
must be present.
Failure to follow any portion of the procedures may cause the entrant to be disqualified.
It is the supervisor's responsibility to ensure that the rules are followed.
After harvesting, weigh the corn as soon as possible.
As the supervisor, you must remain in visual contact
with the corn throughout the entire transportation
and weighing process.
Make sure that the scale used is a state-certified scale
with a current inspection sticker.
Attach the original weight ticket(s) to the Harvest Form.
The ticket must have the name of the weighing company and the person who performed the weighing.
Moisture testing is an important part of the process. Test the sample three times, using an average of the three.
Since the moisture percent must be indicated on the harvest form,
you can either:
Attach the moisture ticket to the harvest form
or
Write the moisture percent directly on the form.
