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 early maturity hybrids (107 day RM or less) at 2 locations, mid maturity hybrids (108-112 day RM) at 7 locations and full season hybrids (113 day RM or more) at 4 locations. The Chesapeake location had early and mid-season entries, and as a maturity group, the mid-season hybrids yielded 18 bushels per acre higher than the early hybrids. The Ag-Expo site in Northumberland County had all three maturity groups, and under drier conditions, the mid maturity group yielded 4 bushels per acre better than the early hybrids. 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.
