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.

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.
