These demonstration and replicated studies provide information that can be used by Virginia corn growers to make better management decisions on their farms. Refer to individual results for more details.
Corn hybrid selection continues to be challenging. With more seed companies and more GMO options and seed treatment packages than ever before, hybrid selection can be a difficult decision. We evaluated mid maturity hybrids (108-112 day RM) and full season hybrids (113 day RM or more) at 5 locations each. One of the mid maturity locations was double cropped and irrigated and hybrids averaged over 200 bushels per acre. One of the full season locations was also irrigated. Yields in all plots were good to excellent. In plots with both the mid and full season hybrids, the full season hybrids averaged 2 bushels more at one location and 7 bushels more at the other location. Farmers should continue to plant hybrids of multiple maturities to help spread risk. In fields with very good soil types and/or irrigation, farmers should consider mid or full season hybrids.
