    INMAN M.D.; VANN M.C.; FISHER L.R.; JORDAN D.L.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Field experiments were conducted to determine the critical period for weed control (CPWC) in flue-cured tobacco. This period consists of two separately measured timings; a critical weed-free period and a critical timing for the weed removal period. ...

    Addressing calcium deficiency in flue-cured tobacco

    VANN M.C.; FISHER L.R.; INMAN M.D.; WHALEY W.T.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, U.S.A.
    With the exception of potassium and nitrogen, calcium (Ca) accumulation by flue-cured tobacco is greater than all other nutrients. Despite such high demand, Ca application is not recommended to well-limed soils. In 2015, Ca deficient tobacco was visually ...

    Evaluation of potassium rates, application methods, and application timing for flue-cured tobacco in North Carolina

    VANN M.C.; FISHER L.R.; STEWART A.M.; SMITH W.D.
    North Carolina State University, Raleigh, NC, USA
    Research was conducted in 2009 and 2010 to evaluate the effects of various potassium rates and application methods on yield and quality of flue-cured tobacco. Locations were the Upper Coastal Plain Research Station in Rocky Mount, NC and the Oxford ...

    Current status of field testing program for pesticide residues in North Carolina flue-cured tobacco

    STEWART A.M.; FISHER L.R.; PARKER R.G.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Research was conducted from 2007 to 2009 at two locations in North Carolina to evaluate cured leaf residues resulting from the application of maleic hydrazide, flumetralin, butralin, cypermethrin, imidacloprid, or azoxystrobin to flue-cured tobacco. All ...

    Effect of lower leaf removal on yield, quality, and grade distribution of flue-cured tobacco

    FISHER L.R.; SMITH W.D.; PARKER R.G.; TAYLOR Z.G.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Lower stalk grades are not in as high demand as upper stalk grades by leaf dealers and some cigarette manufacturers. Many leaf purchasers in the United States have expressed interest in eliminating lower stalk grades of flue-cured tobacco. In addition, ...
