Research Project: NATIONAL TURFGRASS EVALUATION PROGRAM

Location: Floral and Nursery Plants Research Unit

2009 Annual Report


1a.Objectives (from AD-416)
The objectives of the National Evaluation Program (NTEP) are to develop and coordinate uniform evaluation trials of turfgrass varieties and experimental selections in the United States and Canada.


1b.Approach (from AD-416)
Cooperate with university and private industry personnel in establishing, maintaining and collecting data from turfgrass trials. The NTEP will be responsible for the summarization and distribution of data collected


3.Progress Report
National Turfgrass Evaluation Program tests are initiated, established, maintained and evaluated using standardized testing protocols. Data is collected across the U.S.A. and Canada by university researchers using standard procedures and formats. Data is submitted to NTEP, computer formatted and statistically analyzed. Cultivars with superior disease, drought, heat and cold tolerance have been identified as well as cultivars with improved traffic tolerance. This information will be useful to turf managers in reducing pesticide, water, and fertilizer use, thereby reducing environmental impact while maintaining the quality desired by users.


4.Accomplishments
1. Testing turfgrass for tolerance to traffic. National Turfgrass Evaluation Program tests are initiated, established, maintained and evaluated using standardized testing protocols. Data is collected across the U.S.A. and Canada by university researchers using standard procedures and formats. In the cool-humid cool-arid portions of the U.S., perennial ryegrass and Kentucky bluegrass are the major species currently established on athletic fields, parks and other heavily-worn areas. In addition, millions of pounds of these two species are seeded each year on new or renovated athletic fields, parks, etc. Trials of Kentucky bluegrass and perennial ryegrass at multiple locations in the cooler, northern regions have yielded considerable data on establishment, traffic tolerance, disease resistance and overall hardiness of new experimental selections and commercially available cultivars. Data collected and compiled over several years will allow turf managers to make more informed choices on traffic tolerant grasses, resulting in significantly improved parks and athletic fields.

2. Summary of the 2002 NTEP Zoysiagrass Trial, data from 2002-2006. National Turfgrass Evaluation Program tests are initiated, established, maintained and evaluated using standardized testing protocols. Data is collected across the U.S.A. and Canada by university researchers using standard procedures and formats. Data collected and summarized from this trial showed significant improvements in color, density, disease resistance and cold tolerance. In addition, data summarized regionally or by a particular management level revealed cultivar performance difference that allows turf managers and homeowners to better select improved cultivars for their geographical location and situation.
