Planting: July last week to August
1st week
Marketing: November to January
Harvesting and curing: Usually
lower leaves harvested as in flue-cured, then stalk cut and
cured with remaining leaves intact. Cured under ambient temperatures
and humidity, with a limited amount of artificial humidity
control in some cases, to enable complete loss of starch and
practically all sugar. 21-35 days curing time. Cured leaf
is cinnamon-brown in colour.
Environment: More fertile,
stronger soils, to produce good yields of well-expanded, open
structured leaf for its high filling power and absorbing properties.
Also, to shift leaf chemistry towards the nitrogen compounds
and away from carbohydrates (hence the low sugar content of
burley). Has similar climatic requirements to flue-cured,
but specially requires high natural humidity during curing
to avoid premature drying of leaves.
