Genetics for Lee County

Seed that earns its population.

Dyna-Gro®, Proven®, and a full bench of regional genetics. We place hybrids and varieties by soil, drainage, and how hard you push nitrogen — not by what is left on the pallet.

Treated corn and soybean seed

The Steward seed desk

Placement is the product.

Northern Illinois is not one yield environment. Sand streaks, tight clay, and tiled black ground sit in the same section. A Steward consultant walks those differences before a bag is tagged to a field.

  • Corn hybrids selected for relative maturity, root structure, and disease package.
  • Soybean varieties matched to SCN pressure, iron deficiency risk, and harvest timing.
  • Seed treatments and custom enhancements for early vigor and insect windows.
  • Variable-rate seeding maps when the field can pay for the extra management.

How we pick

Four questions before a hybrid list.

A

What does the soil actually do?

CEC, organic matter, and drainage tell us more than a county average. We use multi-year imagery and your soil tests when they exist.

B

How aggressive is the fertility plan?

A racehorse hybrid on a maintenance nitrogen rate is a disappointment. We pair genetics with the nutrition page, not against it.

C

What is the disease history?

Gray leaf spot, SDS, white mold, and tar spot change the conversation. Protection programs start at the seed treatment bench.

D

When do you need to harvest?

Maturity spread is a logistics tool. We build a field-by-field calendar so the dryer is not the bottleneck.

Availability moves with the season. Call the branch before you lock a whole farm to a single bag tag.

Bring last year’s plot book. We will argue with it.

A 20-minute seed conversation at 1793 Steward Rd often saves a 20-bushel argument in October.
