The National Turfgrass Evaluation Program (NTEP) is designed to develop and coordinate uniform evaluation trials of turfgrass varieties and promising selections in the United States and Canada. Test results can be used by national companies and plant breeders to determine the broad picture of the adaptation of a cultivar. Results can also be used to determine if a cultivar is well adapted to a local area or level of turf maintenance.  For more information see Information or Contact Us.

2022 Trials update

Due to a cool spring in the Willamette Valley, and a resulting late harvest, we have moved the deadlines back for receipt of entries into the 2022 Perennial Ryegrass and 2022 Cool-season Fairway Water Use and Drought Tolerance trials. The deadline for entries into the 2022 perennial ryegrass trial is now Monday, August 22nd.

The Cool-season Fairway Water Use trial deadline is now Monday, August 29th. In addition, we will not enforce the 2x entry fee requirement for entries that arrive four days past the deadline (P. Rye-Friday, Aug. 26th, Cool-Season FW Water Use-Friday, Sept. 2nd). Please send seed by the deadline but if you need extra time, we will honor (and not charge 2x) seed received for days later.

Updated entry application forms for the perennial ryegrass and cool-season fairway water use trials are attached. If you have any questions, please let us know.
