charlieharper-ga,
The information you are looking for is available in this report of
chamomile (and other herbs) crop yields at a plot in Cambridgeshire:
http://www.ienica.net/usefulreports/herbs.pdf
SMALL SCALE STUDY OF YIELD AND QUALITY OF OILS FROM SIX HERB SPECIES
"...Six herb species were grown for their yield of essential oil at a
site in Cambridgeshire..."
The crops grown included German chamomile (Matricaria chamomilla or
recutita) and Roman chamomile (Anthemis nobilis).
==========
Section 4.3 of the report provides the "Crop yield and quality assessments":
German Chamomile -- Yields ranged from 20,861 to 26,400 kg/ha:
Whole crop fresh herb...(small sample) 26,400 kg/ha
Whole crop fresh herb...from 44mē 20,861 kg/ha
Roman chamomile -- only one sample was taken, with a yield of 9,500 kg/ha:
"...The whole fresh herb was harvested and this gave a yield of 9,500 kg/ha..."
==========
Section 3.4 provides Individual cultural details of the crops.
German Chamomile was grown as follows:
"...A 1,800 mē plot of chamomile was established using a Veg-row transplanter
machine at 30 cm in-row and 30 cm between the rows giving a population density of
74,074 plants/ha..."
Conditions were the same for the Roman Chamomile crop.
==========
Appendix IV of the report details the weather (temperature/rainfall)
conditions during the study.
Appendix VI provides contact information for the various experts and
suppliers consulted for the project.
As you can see, the yields are quite variable, depending on the
particular chamomile crop planted.
I trust this information fully answers your question.
However, please don't rate this answer until you have everything you
need. If there's anything more I can do for you, just post a Request
for Clarification, and I'm happy to assist you further.
