On-Farm Corn Hybrid Trials
Is Version Of
Farmers are faced with hybrid selection decisions each year as new hybrids are introduced, including transgenic hybrids with several traits for insect and herbicide resistance. As problems with corn rootworm resistance to Bt corn continue to be found in Iowa, it is important to research methods to manage this pest. The objective of these trials was to compare corn hybrids on corn yield and/or resistance to corn rootworms.
