- Association Low-vigour Sangiovese vines had lower leaf area than high-vigour vines.
- Association Low-vigour Sangiovese vines had lower yield than high-vigour vines.
- Association Low-vigour Sangiovese vines had higher berry sugar concentration than high-vigour vines.
- Association Low-vigour Sangiovese vines had higher anthocyanin concentration than high-vigour vines.
- Association Wines from low-vigour vines had better sensory attributes than wines from high-vigour vines.
- Observation Low-vigour wines had excessive ethanol content.
- Association Total soil nutrients were lower in the low-vigour zone than in the high-vigour zone.
- Observation Soil water content of low-vigour vines approached wilting point in 2008, unlike high-vigour vines.
- Association Differences in vigour, yield and must and wine quality were linked to soil fertility and water retention capacity.
- Recommendation Precision management with supplementary fertilization and irrigation should be used to increase vigour and yield in low-vigour vineyards.
- Recommendation Precision management with supplementary fertilization and irrigation should be used to decrease sugar content in low-vigour grapes.
- Recommendation Evaluation of within-field variability is crucial for site-specific vineyard management.
