Yield Challenge Rules

Eligibility

Any Illinois soybean producer (owner-operator, tenant or tenant landlord) who produces 10 acres or more of soybeans in Illinois is eligible to enter. A producer may make more than one entry per category, as long as the entries are from different fields. However, each entry has to be registered independently. A producer with more than one entry will be eligible for only one award per category entered. There are no restrictions on management practices applied; however, a single variety must be planted. ISA reviews and determines eligibility of all entries.

Field Requirements

Field size must be at least a minimum of three continuous acres. A minimum of two acres must be harvested from this area. The harvest area may be more than two acres. The field measurement and yield determination must be made under the supervision of a third-party witness.

Field Requirements

The field or portion of a field entered (a minimum of two acres) must be one continuous area with four straight sides. Plot width will be measured from the first harvested row on the left to the first unharvested row on the right (to assure that inclusions of the equivalent of one-half the average row width beyond the outside harvested row on each side). The measurements can be made by a third-party witness, such as an FFA advisor, crop insurance agent, ag lender, university personnel or other impartial witness (approved by the committee). All measurements must be with a steel or fiberglass tape or measuring wheel and recorded in feet. Each measurement should be recorded on the proper Harvest Report Form (Side-by-Side Plot Harvest Form or 100-Bushel/Crop District Shootout Harvest Form). If a whole field is harvested and entered in the contest (and due to the irregular shapes and dimensions of whole fields), the acreage determination for the whole field will be accepted from the County FSA Office as determined from official USDA aerial photographs.

Yield Determination

A third-party witness, such as an FFA advisor, university personnel, crop insurance agent, lender or other impartial witness (approved by the committee) must be present to supervise measuring, harvesting and weighing of the yield for each entry. For the Side-by-Side Plot Challenge, a single witness is required. For the District Shootout, two witnesses are required. For the 100-Bushel Challenge, two witnesses are required with one being provided by ISA.

Before the plot is harvested, the person supervising the harvest must ensure the entrant has emptied the combine, so no soybeans have been left in it and the wagons and/or trucks in which the contest yield will be weighed are empty.

Harvested soybeans may be weighed in a grain weigh wagon or on a certified scale. A third-party witness must be present during the harvesting of the two-acre section for the contest. The witness must verify with a signature that all harvest data is correct on the proper Harvest Form (Side-by-Side Plot Harvest Form or 100-Bushel/Crop District Shootout Harvest Form). A representative sample must be taken immediately for determining moisture content. For the 100-Bushel Challenge, grain must be weighed on a certified commercial scale and the original scale ticket submitted with the 100-Bushel Harvest Entry Form.

Yields will be calculated on the basis of No. 1 soybeans and will consist of the weight of harvested soybeans, corrected to 13 percent moisture and converted to bushels per acre. Percent moisture should be determined by a local elevator operator or take an average of three moisture samples. Foreign matter does not need to be determined this year.
