This project compares the yield, disease incidence, management costs, and overall economic performance of Marlborough Sauvignon Blanc under two different pruning systems: standard cane pruning and an alternative long spur pruning method. Initial data collected over three years indicated that long spur pruning shows strong potential as a viable alternative to cane pruning in Marlborough vineyards. Benefits observed in the initial trials included reduced labour requirements and improved compatibility with mechanisation, in all but one vineyard.

To build on these findings, this project will support a further two years of yield-focused observations to determine whether the positive results from the initial study will continue over time, and will provide a useful decision-making tool to help growers decide whether to adopt or not adopt long spur pruning in their operations.
