Selecting and matching the right hybrids to soils on your farm and for your needs & purpose is one of the most important decisions you will make for meeting your yield goals. Make the hybrid selection on a field-by-field basis and check out the following points:
• No-till, minimum-till or conventional — Hybrids for no-till ground should have very good seedling vigor and strong disease tolerance package.
• What is the CEC and pH value? Hybrids do differ in their response to different soil types. Soil Type Response — Is the soil sandy, loam, clay, with high organic matter content?
• For lighter ground select hybrids with Drought, Heat and Stress Tolerance — Even though we had two years of good growing weather, you never know when Mother Nature wants to turn the heat on again. Hybrids with good drought and stress tolerance are available from Seed Consultants.
• Hybrid Maturity — Generally, full-season hybrids for your area will have the highest yield potential. However, shorter, early maturity hybrids that may be planted at higher populations for earlier harvest may be part of your plans.
• Row Width — Are you in 15-inch, 20-inch, 30-inch twin rows or wide rows? Make sure your hybrids have upright leaves if you are using narrow rows. Also, shorter hybrids may be better for narrow rows.
• Previous Crop — Certain hybrids are not suitable for corn after corn. If you have to plant corn after corn in some fields, you need hybrids with excellent seedling vigor plus good disease tolerance package.
• Previous Herbicide used — Did you use conventional herbicides, glyphosate or Liberty?
• Herbicide to be used this year — If you are planning on using glyphosate or Liberty herbicide, make sure your hybrid has the gene for resistance to the particular chemical. You may also check with your neighbor to avoid the risk of drift to or from his direction.
