We will set a reGold Country Seed There are hundreds of products to cord for the longest growing season, and choose from, so here are a few suggesin parts of the state, the wettest year, as tions to consider. well. • An agronomist at the University of So, naturally, full-season varieties and Minnesota once told me, “Farmers base their decisions more offensive lines topped most plots. Be careful about too much on what happened last year,” rather than the loading up too much on very full-season lines for 2017. past five or 10 years, and I think he is right. Normally, full-season lines will yield best, but be sure I find myself doing this when it comes to making corn to have a mix and not stack the deck with all full-season products. • For fields that are in continuous corn, select hybrids that have good roots and stalks, and have a good disease package – especially for Goss’s Wilt. Continuous corn fields simply have more stress than fields in a two- or three-crop rotation, so a healthy root and stalk are important traits to select. In warm dry summers, continuous corn fields can yield as much as 30 percent less than rotated corn. • For soybean growers in a corn/ soybean rotation, select soybean lines that have a good disease package. Oftentimes, one of these diseases – phytophthora root rot, brown stem rot, white mold, and occasionally sudden death – infect plants and reduce yield. White mold is especially common in fields that have a livestock manure history. Lowering plant populations to 140,000 seeds or less will also help manage white mold. • Work with your seed dealer to select products that are a good fit for each field. Some products have better drought-tolerance. Others are more offensive, and should be placed in your most productive soils. Fields coming out of alfalfa should not need rootworm protection. These are all things best discussed with your seed dealer, to find a package of products that best fit your operation. n
