STOCK (required field)
Plants for this crop were derived from:

 

SEED = Plants are from germinated seeds

CLON = Clones

MIX = Combination of clones and plants from seed

REVE = Plants revegetated from flowering plants

Seed vs clone stock is included to indicate that possibly males have been removed thus leaving a canopy that "could" have yielded more with the given hardware. With clones I feel it's safe to assume a full canopy.
