Corn Hybrid Grain End-Use Ratings Syngenta is committed to sharing agronomic knowledge with our customers to help them grow more corn. The Corn Hybrid Grain End-Use Ratings provide information that can help our customers who produce corn for livestock, the ethanol industry or other grain end uses where grain quality can be just as important as grain yield. These Corn Hybrid Grain End-Use Ratings are supported by collecting grain samples from internal company trials which are sent to an independent laboratory for protein, oil and starch analysis.

The data from these analyses are then categorized for the end-use based on the level of each characteristic with four ratings: Best (Highest level); Good (Above average level); Fair (Average to below average level); Poor (Low level).

Starch content and quality are important characteristics for maximum ethanol production.

Protein content is a key factor in feed value for livestock.

Factors Influencing Grain End-Use Characteristic Content Multiple factors influence grain end-use characteristics. Some of these influences are:

• Environment – Corn grown in the northern US tends to be higher in protein, but corn grown in the central and southern US tends to be higher in starch.

• Genetics – Some hybrids will consistently produce higher levels of specific grain end-use characteristics, regardless of growing conditions and crop management.

• Soils – High fertility soils tend to produce higher levels of protein.

• Management – Proper nitrogen fertility correlates to increased protein levels.

Note: Always select hybrids first based on local adaptability and then consider grain end-use characteristics.

End-use Characteristics Matter for Producers
