6. Burley Tobacco Variety Trial Across 7 Locations – 4 Grades Locations: Clinton, Henry, Taylor (3), Trimble & Wayne Counties

7. Varieties Will Be Screened Varieties may have some plants in the population that produce a high amount of nornicotine () Varieties may have some plants in the population that produce a high amount of nornicotine (Converters) Nornicotine may lead to NNN (Nitrosonornicotine): one of the tobacco specific nitrosamines Nornicotine may lead to NNN (Nitrosonornicotine): one of the tobacco specific nitrosamines By cleaning up the variety so that most plants have a low level, NNN will develop at only a low level By cleaning up the variety so that most plants have a low level, NNN will develop at only a low level

8. How Do We Know If the Variety is Screened? “LC” varieties “LC” varieties  KT 204LC, KT200LC, TN 97LC,  TN 90LC, TN 86 LC, KY 907LC “Produced from screened parents” “Produced from screened parents” Exceptions Exceptions  KY14 x L8, KY14, KY17 (Available in 2006)  Some private varieties

9. Some Varieties Will Be Dropped Screening is expensive and older varieties would cost too much for upkeep Screening is expensive and older varieties would cost too much for upkeep Good alternatives are available to replace most older varieties Good alternatives are available to replace most older varieties  A good disease package will be essential  14 x L8  High management  Tendency to initiate suckers early  KY 907  Lodging & quality  TN 86  Quality

24. Topping Top can vary by company Top can vary by company  May change in the future Top to 23-24 leaves Top to 23-24 leaves  For companies looking for more tips Topping height can influence other factors Topping height can influence other factors  Leaf spread  Cured leaf color  Root development  Nicotine levels  Disease incidence

25. Harvest date Harvest mature tobacco  Usually at 4 weeks after topping  Weather may delay  Late maturing varieties may need more time Quality Yield

27. Curing Burley Tobacco

28. Curing Problem Low humidity/high temperature   Drying, not a cure Low humidity/satisfactory temperature   Variegated, piebald or green tobacco Low or high humidity/low temperature   Green tobacco High humidity/high temperature   House burn, microbial growth and excessive weight loss

29. What Kind of Curing Facility Inefficient labor use Construction expense Long term investment Other uses Slow change in conditions Forced ventilation? Nitrosamines? Efficient Inexpensive Limited lifetime Not for storage Daily cycle of conditions Nitrosamines ? Improved color?

30. Market Prep & Storage Wait till cure is complete Wait till cure is complete  No fat stems Avoid Avoid  High moisture  High pressure during baling  Non-tobacco related material Storage Storage  Minimal amount of time  Avoid plastic  Provide ventilation Close supervision of stripping crew?
