“Comparing and Contrasting Vertical Shoot Positioning and Top Wire Cordon Training Systems”
is coming up on Tuesday, February 10th, 2015, at two times:
- 12:00 Noon Eastern (11:00 am Central)
- 7:00 pm Eastern (6:00 pm Central)
Join Bob Utter of Flying Otter Vineyard and Winery, John Thull of the University of Minnesota, and Tim Martinson of Cornell University as they discuss the pros and cons of Vertical Shoot Positioning (VSP) and Top Wire Cordon (TWC) training systems. Bob will discuss TWC, including the advantages (including reduced labor, frost protection, and varmint predation), disadvantages, and how to convert from VSP to TWC. John will cover how the narrow canopies created on VSP trellises allow for great sunlight interception and lower disease pressure, and the control that VSP gives the grower in the way of canopy management and what mechanized practices can be implemented. Tim will talk about the training system trials in New York on Marquette and Frontenac, and the differences observed between them, including yield and fruit composition.
