A little background on the project -

For this project we will be evaluating alternative strategies for under-trellis (under-vine) management through research projects and demonstration plots that explore a range of management options including mowing and the use of seeded perennial groundcovers. We will include a detailed examination of management practices on vine growth, fruit composition, and nitrogen use. By incorporating data and observations from research and demonstration plots, growers will possess the knowledge and tools for evaluating and implementing alternative strategies in their own vineyards.

Our group will survey regional growers to determine current under-vine management practices and assess experience with alternative strategies. We will coordinate presentations of preliminary results from green cover projects in Virginia and the Finger Lakes to spark grower interest. In the research projects and demonstration blocks vine/fruit impacts will be documented throughout the season by educators with assistance from industry personnel. Grower-advisors will host field meetings at their vineyards and participate in evaluation and follow up of the trials. They will mentor other growers, in person and via this blog, as they implement these strategies.

These efforts will benefit the Long Island wine industry as well as winegrape producers throughout eastern North America. We will extend project progress and results to local and regional growers through educational activities such as newsletter articles and posts to this blog. Presentations at summer field meetings and winter meetings will facilitate discussion of management strategies. Ultimately, we hope to see Long Island growers adopt green cover management strategies and anticipate savings in reduced herbicide costs, application costs and canopy management costs.
