    Effects of genotype and cultural practices on flue-cured tobacco growth, development, and chemistry

    VANN M.C.; CHEEK J.A.; MACHACEK J.L.; WHITLEY D.S.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    The reintroduction of proposed nicotine standards by the US-FDA warrants further investigations of selected tobacco genotypes and management strategies that may reduce concentrations of the metabolite. To quantify these effects, research was...

    Soil applications of maleic hydrazide do not control tobacco axillary bud growth

    VANN M.C.; WHITLEY D.S.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Increased focus on residues of the plant growth regulator Maleic Hydrazide (MH) have prohibited some U.S. producers from applying the suckercide to control tobacco axillary buds. As such, an alternative to the conventional foliar application of the...
