Featured Research Projects

Efficient Vineyard, 2015-2019

The Efficient Vineyard project seeks to develop sensor and mechanization technology to measure crop load and assess canopy with real-time imaging to enhance our ability to achieve vine balance and eventually develop tools for precision viticulture. This project has now concluded.

High-Resolution Vineyard Nutrient Management, 2020-2023

This project seeks to enable grape growers to make data-driven nutrient-management decisions for spatially heterogenous vineyards and diverse production markets, proposing to develop grower-friendly decision-aid tools for vineyard nutrient management to optimize inputs and business profitability via improved vineyard productivity and fruit and product quality, while minimizing adverse impacts on the environment.

VitisGen2, 2017-2021

In the second phase of this game-changing research, the VitisGen2 team will expand on progress made in developing novel economic, phenotyping and genetics knowledge and tools related to new grape cultivars. And they plan to translate these and previous VitisGen innovations into new applications for improving grape breeding programs and managing existing vineyard plantings.
