Vineyard Establishment and Training Systems
What this domain tests
Vineyard Establishment and Training Systems tests planting decisions and the architecture of the vine: certified planting material, rootstock choice, spacing, trellis, training, pruning and vine balance. The exam rewards calculations and practical sequencing, not just definitions.
Planting and establishment
Use certified, virus-tested planting material and match the rootstock to soil pH, lime, salinity, waterlogging and pest pressure. Prepare the soil by correcting drainage and compaction, controlling perennial weeds and incorporating organic matter where appropriate. Plant dormant vines when soil temperature is adequate and risk of desiccation is low. Keep the graft union above the soil surface to prevent scion rooting, and irrigate newly planted vines until roots establish.
Spacing, training and pruning
Training defines the permanent framework; pruning controls bud number and shoot growth. Common systems include Guyot, cordon, Gobelet and trellised systems with vertical shoot positioning. Row orientation and spacing affect light interception, airflow, mechanisation and disease pressure. Pruning severity is expressed as buds per vine or buds per hectare. Vine balance means the canopy can ripen the crop without excessive vigour.
Worked example
A block has 2.5 m between rows and 1.2 m between vines. Vine density = 10,000 ÷ (2.5 × 1.2) = 3,333 vines/ha. If each vine retains 12 buds, bud load = 3,333 × 12 = 40,000 buds/ha. If the pruning system is changed to 8 buds per vine, the load falls to about 26,664 buds/ha. The lower load may improve fruit quality but can reduce yield if vigour is already low.
Traps that cost marks
Do not bury the graft union. Do not recommend the same rootstock for both waterlogging and severe drought without justification. Do not confuse buds per vine with shoots per vine; not all buds produce fruitful shoots. Do not treat higher planting density as automatically better: soil, vigour and machinery matter.
Key points
- Certified planting material reduces virus and variety risk.
- Rootstock choice must match soil and pest constraints.
- Graft union placement affects scion rooting and long-term health.
- Bud load per hectare combines density and pruning level.
- Training and row orientation influence light, airflow and mechanisation.
