Below, you will find the results of the 2023 N.C. Cooperative Extension Upper Coastal Plain regional corn hybrid evaluation. This year’s evaluation included eleven locations across eight Upper Coastal Plain counties, including Bertie, Edgecombe, Halifax, Hertford, Martin, Nash, Northampton, and Washington. Each participating county included one dryland site, while Nash and Northampton counties also included an irrigated site. Note: All sites used the same check hybrid (e.g. Dekalb DKC67-44VT2P), which was placed on the outside borders of the plot and then once every third tested hybrid within the plot.
This year, we set up the evaluations so the grower could install a hybrid of their choice within the study. On average, they selected well for the dryland environment.
In the document on page 1, you will find the test hybrids listed in descending order according to average yield across the dryland locations, with a rank of “1” indicating the highest yield and a “21” for the lowest yield. The top three hybrids ranked are indicated by color, with blue, red, and yellow for 1st, 2nd, and 3rd, respectively. To the right side of the table, you will find a similar ranking system for the irrigated only sites. You’ll find the ranking for the dryland and irrigated sites combined to the far left.
On page 2, you will see the relevant production information for each site.
A special thank you goes out to each location’s participating growers and facilities. Without your cooperation and support, this level of investigation would not be possible.
We would also like to thank the Corn Growers Association of North Carolina for supporting this effort. Through their support and with the continuing support from our local agribusiness partners, we generated this data across a large area of North Carolina while maintaining a local focus.
