Purdue Annual Turfgrass Research Report

Purdue Annual Turfgrass Research Report

As the green industry continues to have a large impact on Indiana and the nation, Purdue University has assembled an outstanding team of researchers, extension personnel, and educators that are dedicated to solving problems and helping meet the needs of Indiana residents. One segment of the Indiana green industry that continues to provide a significant impact on the state’s economy is the turfgrass industry, which includes residential and commercial lawn care, sports turf, cemeteries, sod production, golf course maintenance, and more. Indiana’s professional turfgrass industry is estimated by some to generate in excess of $1.4 billion in annual expenditures and provide over 11,500 jobs.

The Annual Report of the Purdue University Turf Program is published each year by the Purdue Turf Team and features significant findings made by turfgrass scientists over the past year. It is our desire that this publication will keep our stakeholders up-to-date on significant changes and advancements that affect our industry.

This 2011 Annual Report includes 21 papers from faculty, staff, and graduate students. We hope that these findings will enhance your ability to conduct business in an efficient and productive manner.

We would also like to recognize the many organizations, companies, and individuals who have contributed their time, talent and resources to help make our program successful. We are forever indebted to the many people who contribute to this program. Special recognition goes to the Midwest Regional Turf Foundation which supports the research and extension programs of each member of the Turf Team and also provides substantial support towards the operating and capital expenses of the W.H. Daniel Turfgrass Research and Diagnostic Center.

We hope that this publication will be of value to all persons with an interest in the Indiana green industry. To read more about our recent research, click on the links below or read more from the turf homepage at: http://www.agry.purdue.edu/turf/research-annual-report.html
