Argronomic tools to support a whole system approach to reducing water risk in rain dependent and supplementary irrigated viticulture

The aim of this project is to develop management strategies that irrigated, rain-dependent vineyards can apply during a drought to minimise the loss of yield and grape quality, through a better understanding of vine and cover crop water use. Through a modelling approach, management strategies to better follow seasonal water availability will be proposed, and the implications of cover crop water use traits for water competition and longer-term vineyard water use efficiency will be tested.
