    Auxin herbicide exposure: comparisons of 2,4-D and dicamba drift to flue-cured tobacco

    VANN M.C.(1); JORDAN D.L.(1); FISHER L.R.(2)
    (1) North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.; (2) NC Agriculture Research Service, North Carolina State University, Raleigh, NC, U.S.A.
    Auxin herbicide application has increased in North Carolina due to the commercialization of 2,4-D and dicamba tolerant crops. Flue-cured tobacco is extremely sensitive to both herbicides, yet is commonly grown in close proximity to genetically...

    Lower-leaf removal programs for flue-cured tobacco production in North Carolina

    COGGINS T.; VANN M.C.; FISHER L.R.; WELLS R.; BROWN A.B.; FINCH C.E.
    North Carolina Cooperative Extension Service - Davidson County, Lexington, NC USA
    Sluggish demand for lower-stalk positions has prompted consideration for de-lugging programs in North Carolina. The agronomic impact of these leaf removal systems has not been fully reported. The objective of this research was to compare lower-leaf...

    Establishing application protocols for poultry litter and feather meal in organic Burley tobacco production

    SUCHOFF D.H.; VANN M.C.; FISHER L.R.; WHITLEY D.S.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Information on nutrient management in organic Burley tobacco is limited. Unlike conventional nitrogen (N) sources, which are readily available for plant use upon application, organic N fertilizers require microbial mineralization to become plant...

    Implications of chloride application rate and nitrogen fertilizer source on flue-cured tobacco

    VANN M.C.(1); HARDY D.H.(2); FISHER L.R.(1)
    (1) North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.; (2) North Carolina Department of Agriculture & Consumer Services - Agronomic Division, Raleigh, NC, U.S.A.
    Chloride (Cl-) assimilation by flue-cured tobacco can be toxic and may negatively impact leaf quality and combustion when tissue concentration exceeds 1 %. Uptake is influenced by exposure to NH4+ and Cl-, particularly that coming from fertilizer....

    Lower leaf removal and nitrogen application programs for flue-cured tobacco production

    VANN M.C.(1); FINCH C.E.(1); FISHER L.R.(1); WELLS R.(1); BROWN A.B.(2)
    (1) North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.; (2) North Carolina State University, Department of Agricultural & Economic Resources, Raleigh, NC, U.S.A.
    With a current global over-supply of flue-cured tobacco, tobacco producers in North Carolina have been encouraged to remove the lowermost leaves prior to harvest due to their low value in manufactured products. The objective of this research was to...
