Planting density: arrangement, not yield
The standard
A declared planting density names its reference area and its two spacings: row and vine spacing, from which the number of vines per hectare follows.
Criteria
- The figure refers to a named area, usually the hectare
- Row spacing and vine spacing are both stated
- It is counted from the planted area, not the gross area
- It describes the arrangement, not the harvested quantity
Distinction
Planting density ≠ yield: the density describes the arrangement of the vines, the yield the harvested quantity per area. A high declared planting density distributes a given quantity over more vines; it does not raise or lower the yield by itself.
