    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....
