KingFisher & Red Tail Corn Seed Hybrids

Field corn seed for silage, grain, and livestock feed.

Better Forage. Better Feed.

Whether you’re feeding a dairy herd, backgrounding beef cattle, or planting a deer food plot, KingFisher and Red Tail hybrids are bred and rated to match agronomic performance, grain yield, and feeding quality to your goals.

Corn Hybrids Chosen Through Years of Testing, Not Just One Good Season

Every hybrid we offer is built on the same three-legged stool: agronomic performance, grain yield, and feeding performance — a dependable base to build on no matter what the growing season brings.

Before a hybrid earns a place in the lineup, we test it for FiberGest (fiber digestibility) and SofStarch (starch digestibility) in our own lab, then run it through an average of three years of plot testing across multiple states, comparing it against the cornerstone hybrids already in the lineup. Only a small fraction of the hundreds of hybrids we evaluate make the cut.

FiberGest

Measures fiber digestibility (NDFd) to support higher-quality forage and improved feed efficiency.

SofStarch

Measures starch digestibility to help dairy and beef producers capture more feeding value from every ton of silage.
That rigor shows up in the results: since 2018, KingFisher and Red Tail hybrids have earned a Grand Champion title at the World Forage Analysis Superbowl in seven of the last eight years, including back-to-back sweeps of both the Standard and BMR Corn Silage categories in 2022 and 2025.

What Type of Corn Are KingFisher & Red Tail Hybrids?

KingFisher and Red Tail are dent (field) corn hybrids developed for silage, grain production, livestock feed, and food plots. Unlike sweet corn, they’re bred for agronomic performance, feed quality, and grain yield rather than fresh eating.

Ideal for:

  • Silage production
  • Grain harvest
  • Dairy and beef feed
  • Wildlife and deer food plots

Check out the 2027 Corn Hybrid Guide, with full maturity, FiberGest, and SofStarch ratings for every hybrid, to find the best fit for your farm.

KingFisher & Red Tail Hybrid Lineup

Our full lineup of corn hybrids is organized by relative maturity (RM), making it easy to compare options for your growing season and harvest plan.

KingFisher hybrids are conventional and non-GMO, with several available for organic systems. Red Tail hybrids carry insect- and herbicide-tolerant trait packages, including Power Core® Enlist®, Duracade®, Agrisure®, and Viptera® options, for farms that need above- and below-ground pest control or added weed-management flexibility, and many share the same base genetics as their KingFisher counterparts.

Frequently Asked Questions About KingFisher & Red Tail Corn Seed

KingFisher and Red Tail are field corn (dent corn) hybrids, not sweet corn. Field corn is grown for silage, livestock feed, grain production, and food plots, while sweet corn is harvested fresh for eating. If you’re looking for sweet corn or ornamental varieties for the garden, this isn’t the right lineup.

The best hybrid depends on your growing season, feeding goals, soil conditions, and harvest plans. Relative maturity (RM), FiberGest fiber digestibility ratings, SofStarch starch digestibility ratings, disease tolerance, and trait packages all play a role. Your local King’s AgriSeeds seed advisor can help match the right hybrid to your operation.

Yes. KingFisher hybrids are conventional, non-GMO field corn, with several options suitable for organic production. Red Tail hybrids include insect- and herbicide-tolerant trait packages for farms that need additional pest or weed management flexibility.

[Client to confirm.] KingFisher and Red Tail corn seed is sold by the unit. Please confirm the seed count per unit so we can provide accurate planting recommendations.

[Client to confirm.] Please confirm the standard seed count per unit (for example, 80,000 seeds) so customers know what to expect when ordering.

[Client to confirm.] The number of acres depends on your planting population. At typical seeding rates, one unit generally plants approximately 2.5 to 3 acres, though this varies depending on whether you’re planting for grain or silage. Your King’s AgriSeeds seed advisor can help determine the right population for your goals.

Recommended planting populations vary by hybrid and growing conditions but generally range from 26,000 to 34,000 seeds per acre, with some specialty hybrids performing well at higher populations. Your local seed advisor can recommend the ideal population based on your hybrid selection, soil type, and management practices.

KingFisher and Red Tail hybrids are developed specifically for livestock producers. Every hybrid is evaluated for agronomic performance, grain yield, and feeding performance, including FiberGest fiber digestibility and SofStarch starch digestibility, to help dairy and beef producers maximize forage quality and feed value.

Yes. While these hybrids are primarily developed for silage, grain, and livestock feed, many also perform well in deer food plots and wildlife plantings. Your local King’s AgriSeeds seed advisor can recommend hybrids and maturities that best fit your location and management goals.
