Planting: October 1st week to
November 1st week
Marketing: May to June
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 especially requires high natural humidity during curing
to avoid premature drying of leaves.
