New! Introducing KingFisher Corn Hybrids
King’s AgriSeeds and Byron’s, two leading livestock-focused seed companies, are now working together to bring you the KingFisher corn hybrids. The KingFisher brand is a non-GMO lineup, with the intention of adding certified organic hybrids in future years. The KingFisher corn program promises to bring you the same quality, performance, and value that you are already familiar with from the KingFisher alfalfa program. All of our corn hybrids have been selected with an emphasis on high energy and digestibility without sacrificing yield.
Try two or three of our hybrids alongside your current brand. We think you’ll be impressed.
KingFisher hybrids are available both treated and untreated.

KingFisher Specialty Hybrids
KF 56H91 – High Oil
Note: This high-oil hybrid is to be physically mixed at 25% with a hybrid of a similar maturity to increase energy content.
A medium tall plant with flex ears, needs to be used in a sidekick program mixed 25-30% with conventional corn. Optimum planting rate: Dryland – 30-34 M/A Irrigated – 34-38 M/A. Put on your best ground. SideKick™ blend rate = 70% conventional corn + 30% KF 56H91. Increases oil content in the grain 2-3% and protein up to 30%. Contains higher levels of rich essential amino acids lysine and methionine. Excellent drought and heat tolerance. A floury grain; the Value Plus® gives it smaller starch molecules, making it very digestible. SideKick™ gives excellent yield; usually no yield drag compared to your favorite hybrid. Stalk has shown high sucrose levels. Recommended planting pop: 26-30k. RM 106
KF 58H82 – High Oil
A tall plant with great flex and eye appeal. Use on better soils for silage. Best suited for silage, planted at 26,000 to 30,000 potential for very high silage yields under ideal conditions. Contains up to 30% more protein and higher amino acids than regular corn. Excellent yielder, highly digestible stalk and starch. Value Plus® allows you to grow more energy on your farm. High-oil corn – 5-6.5% in the grain. Value Plus® livestock production corn has a smaller starch molecule so starch is more readily available. Recommended planting pop: 26-30k. RM 108
KF 59S30 – Male Sterile
A male sterile hybrid ideal for farms that are in niche markets and do not want grain in the diet. Appropriate for silage and grazing. The corn crop will be very high in sugar as grain is not formed. The plant will also have a red color as sugar increases over time. It’s a versatile hybrid that covers all soil types, with a wide harvest window and an excellent disease package. Note: Isolation from standard corn is recommended. Recommended planting pop: 26-32k. RM 109

MasterGraze is a BMR tillering corn that is ready to graze in 60 days. The brown midrib gives the vegetation a boost in digestibility. Good for one grazing.
Mastergraze must be planted with a corn planter. It is often planted in 15 -inch rows:
32,000 to 36,000 plants per acre on low to medium fertility soil or on doughty soils where moisture availability can be a limiting factor.
34,000 to 38,000 plants per acre on medium fertility soils
36,000 to 40,000 on high fertility soils, with no moisture limitations.
(Double back to split the rows with a 30-inch spaced corn planter). Population will depend on available soil moisture and fertility.
