A potential method of controlling vine vigour is to vary the in-row vine spacing.
This method has been used successfully in other grape cultivars to manage the vigour and improve the productivity and quality of the grapes.
This project tests 4 different vine spacings across 3 different soil types for both Sultana grafted to Ramsey rootstock and Sunmuscat grafted to 1103 Paulsen rootstock (Project no. DG00003)
Matching vine vigour and planting density to maximise dried vine fruit production and quality of cordon based systems
