Each year we conduct multiple irrigated and non-irrigated corn hybrid trials across South Carolina to evaluate hybrid performance, working with seed companies to demonstrate hybrid performance of germplasm that is being sold commercially. In this non-bias, cross-company trial, you will find data that can help make seed ordering decisions for 2026. I encourage farmers to utilize as many sources of hybrid data as possible including Official Variety Trial (OVT) data and industry data to make decisions.
Our research demonstrates that hybrid selection, especially in irrigated situations is critical in maximizing grain yield in South Carolina.
Within this document, (County Level Hybrid Data – 2025) you will find 10 locations of hybrid data that contains: location, irrigated or non-irrigated, planting and harvest dates, seeding rates, row spacing, soil type, hybrid name, company, plant height at harvest, ear height at harvest, harvest moisture, test weight, and grain yield corrected to 15.5%.
We would especially like to thank our cooperators for 2025 in helping us implement these trials, in addition to, the seedsman and companies that have partnered with Clemson to provide seed and hybrid information for these trials.
If you have any questions please contact Dr. Michael Plumblee or your local county agent. If you are a seed company and wish to participate in the 2026 hybrid trials please reach out to Dr. Michael Plumblee at mplumbl@clemson.edu.
