  1. NC STATE UNIVERSITY Burley Tobacco Production Update February 20, 2008 Mitch Smith County Extension Director

  2. 2006 Burley Tobacco Production More than 120 acres NCDA-CS

  3. 2004 Top 5 Counties Madison Alleghany Buncombe Yancey Ashe 2006 Top 10 Counties Rockingham Surry Madison Stokes Buncombe Edgecombe Person Yadkin Caswell Franklin Burley Tobacco NCDA-CS

  4. 2007 Pitt County Burley • 118 acres • 7 county burley producers

  5. Research Areas • Varieties • Planting Date • Harvest Date • N Rate

  6. Variety Evaluation • Comparison of yield potential of burley varieties with flue-cured varieties in the Official Variety Test • Whiteville • Rocky Mount • Burley OVT at Reidsville

  7. Yield of All Varieties in the Burley OVT at Whiteville, 2005 2/18

  8. Yield of All Varieties in the Flue-Cured OVT at Whiteville, 2005 32/45 12/45

  9. Yield of All Varieties in the Burley OVT at Rocky Mount, 2007

  10. Yield of All Varieties in the Flue-Cured OVT at Rocky Mount, 2007

  11. Yield of All Varieties in the Burley OVT at Reidsville, 2007

  12. 2007 Season ResultsPitt County, NC • 80% of county burley acreage was planted in April • All acreage was planted by 2nd week in May • NC 7 and KT 204 represented 76% of acreage • Average nitrogen rate was 342 pounds per acre • Average plant population was 7337

  13. Planting Date • Evaluate several planting dates • Normal • 10, 20, and 30 day delay in transplanting • Original objective was to delay harvest at late as possible without reducing yield • Better curing environment

  14. Yield and Quality of the Planting Date Study in Rocky Mount a a a b Transplanting Date Transplanting Date Normal transplanted on April 20 2006

  15. Yield and Quality of the Planting Date Study in Rocky Mount a a a b Transplanting Date Transplanting Date Normal transplanted on April 24 2007

  16. Harvest Date • Determine optimum harvest date after topping • 20, 30, 40, and 50 days after topping • Is holding ability affected by higher temperatures? • Will burley hold as long after topping in non-traditional areas?

  17. Yield and Quality of the Harvest Date Study in Rocky Mount a a a * b Harvest Date Harvest Date 2006 DAT = Days after topping

  18. Yield and Quality of the Harvest Date Study in Rocky Mount a bc ab c a a a a * Harvest Date Harvest Date 2007 DAT = Days after topping

  19. Nitrogen Rate • Evaluate three nitrogen rates (lbs/A) • 200 • 250 • 300

  20. Yield and Quality of the N Rate Study in Rocky Mount Quality Index Yield (lbs/A) N Rate N Rate 2007

  21. Conclusions • The highest yielding burley varieties commonly yield 10-15% less than flue-cured varieties when grown under similar conditions in our trials • Planting burley in non-traditional areas after the third week of May will reduce yields most years and will not significantly delay harvest date • Harvesting burley ~ 30 days after topping maximized yield and quality most years. Later harvest dates reduce lower stalk yield and quality, however, upper stalk yield may increase. • Upper stalk grades may loose tip character with delayed harvest

  22. Conclusions • There was no yield increase from 200 to 300 lbs of N per acre if tobacco was harvested in a timely manner • Higher N rates did improve yield when harvesting was delayed

  23. Burley VS Flue-cured Rocky Mount OVT, 2007 • Flue-cured NC 71: 3269 lbs/A • Burley NC 7: 2326 lbs/A • Average selling price per pound: • FC: $1.52 • Burley: $1.60 • Profit per acre: • FC: $1770 • Burley: $702 (Based on 2008 Budget, Bullen & Brown)

  25. Diseases of Burley Tobacco

  26. Black Shank kills burley faster than flue cured tobacco June 2006, Hoke Co.

  27. Burley, variety response to black shank Forsyth Co., 2006

  28. Burley, variety response to black shank Forsyth Co., 2006

  29. Whenever possible, plant burley in fields with no disease history!

  30. Black shank Control, 2007 • 4 varieties: NC71, K326, NC7, TN90

  31. Black shank Control, 2007 UCPRS Rocky Mount, 2007

  32. Time of RG application, 2007 • 4 varieties: NC71, K326, NC7, KY204

  33. Time of RG application, 2007Race 1 Surry County 2007

  34. Time of RG application, 2007Race 1 Surry County 2007

  35. 2008 PredictionsPitt County, NC • 64 more acres for 2008 ???? • Plant burley before flue-cured • Plant KT 206 • Provide early season thrips protection • Irrigate • More sticks than wires ???? • Only one buyer for 2008 ????
