Understanding Your Role and Responsibilities During the Contest

credibility which is due in large part to

the network of local supervisors (you) who verify the accuracy

of yields submitted for competition.

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.

6

Initial Yield Checksw/ one supervisor present Cont’d…

Pre-Harvest Inspection

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.

10

Supervisors must be present during:

Harvesting

Transporting

Weighing

Moisture Testing

**The supervisors are responsible for overseeing all computations

and field measurements.

11

Measuring

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

12

Measuring

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.

13

How to Harvest the Plot

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, repeat as neededSix-row harvester Harvest six rows, skip eighteen, harvest six, skip eighteen, repeat as neededEight-row harvester Harvest eight rows, skip twenty-four, harvest eight, skip twenty-four, repeat as neededTwelve-row harvester Harvest twelve rows, skip thirty-six, harvest twelve, skip thirty-six, repeat as needed

14

Calculating Yield Requires

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.

15

Calculating Yield

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.

16

Moisture Testing

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.

17

Harvesting the Plot Cont’d

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/acreTwo 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.

18

In the Field…

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.

19

In the Field…

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.

20

In the Field…

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.

21

In the Field…

***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.

22

At Weighing…

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.

23

Procedure Review

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.

24

Procedure Review

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.

25

Procedure Review

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.

26

Procedure Review

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.
