Density/Yield Flashcards
1
Q
What type of density is required for low nutrients/sufficient rain?
A
High density
2
Q
Why is low density applied for limited water?
A
Roots of vines have a large soil area to get water from
3
Q
Why is high density used?
A
Competition of nutrients between vines
4
Q
Why do the no of buds in a high density area matter?
A
Too few = grow too much
Too many = not enough nutrients
5
Q
Where is high density planting found?
A
Europe
6
Q
What density is applied for high levels of nutrients & rain?
A
Low density
7
Q
What can New World vines planted at low density produce?
A
Good quality @ high yield
8
Q
What is green harvest?
A
Removing immature berries after veraison to reduce yield
9
Q
What happens if green harvest is done too early?
A
The vine overcompensates & results in diluted grapes
