    Efficacy of weekly Agribrom treatments for control of algal and fungal growth in a tobacco transplant float-production system

    KAY S.H.; SMITH W.D.; MINER G.S.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    Two experiments were conducted to determine the effectiveness of Agribrom (1-bromo-3-chloro-5,5-dimethyl-2,4-imidazolidine-dione) for control of algal and fungal slimes on the surface of the growth medium used in the float method for production of tobacco ...

    Cured leaf sampling of small tobacco research plots for chemical analyses

    BOWMAN D.T.; WEEKS W.W.; MINER G.S.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, USA
    The accuracy of chemical plant analyses from small tobacco research plots is dependent on the sampling method and technique. Typically, a 50-g, half-lamina random leaf sampling method is used to determine reducing sugars and total alkaloids in Burley and ...

    Production of flue-cured tobacco seedlings in greenhouses. Effects of media and fertilization on the direct-seeded float system

    JONES M.A.; MINER G.S.; SMITH W.D.
    North Carolina State University, Dept. of Soil Science, Raleigh, NC, USA
    Three experiments in 1990 and one in 1991 were conducted to investigate the effects of soilless media and fertilization on the growth responses and nutrient concentrations of flue-cured tobacco (Nicotiana tabacum L.) seedlings grown in the direct-seeded ...

    Effects of media and fertilization on the greenhouse production of flue-cured tobacco seedlings in the overhead-watered system

    JONES M.A.; MINER G.S.
    North Carolina State University, Dept. of Soil Science, Raleigh, NC, USA
    An overhead-watered fertigation experiment was conducted to evaluate the effects of three fertilizer regimes and six types of soilless media on growth and development of flue-cured tobacco (Nicotiana tabacum L.) seedlings. The fertigation treatments were ...

    Production of flue-cured tobacco seedlings in greenhouses II. Effects of fertilization on the plug-and-transfer float system

    JONES M.A.; MINER G.S.
    North Carolina State University, Dept. of Soil Science, Raleigh, NC, USA
    Three plug-and-transfer experiments were conducted in 1989 and 1990 to evaluate the effects of fertilization on the growth and development of flue-cured tobacco (Nicotiana tabacum L.) seedlings. Various rates of NH 4 NO 3 (0, 67, 133, or 200 mg N L-1 in ...

    Effects of nitrogen source and soil acidity on nitrogen use efficiency and growth of flue-cured tobacco

    CAO Z.H.; MINER G.S.; WOLLUM A.G.
    Inst. Soil Sci. Acad. Sinica., Executive Deputy Dir., Nanjing, China.
    Yield and quality of flue-cured tobacco (Nicotiana tabacum L.) are often reduced by(NH4)2.SO4 on acid soils. Urea is a less acid-forming Source of ammonium than(NH4)2.SO4 and may be a better source of plant nitrogen than(NH4)2.SO4 under acid soil ...

    Effect of soil pH and rates of nitrification inhibitors on nitrification and growth of flue-cured tobacco under greenhouse conditions

    CAO Z.H.; WOLLUM A.G. II; MINER G.S.
    Chinese Academy of Science, Inst. of Soil Science, Nanjing, China; North Carolina State University, Raleigh, NC, USA
    The purpose of this investigation was to determine the effects of soil pH and rates of nitrapyrin and metalaxyl on nitrification and growth and mineral composition of flue-cured tobacco under greenhouse conditions. Soil was amended with a complete NPK ...

    A threshold concept for the management of premature flowering in flue-cured tobacco

    RIDEOUT J.W.; MINER G.S.; RAPER D.C. Jr.
    North Carolina State University, Dept. of Soil Science, Raleigh, NC, USA
    The threshold concept, widely used in pest management, can be applied to the management of premature flowering. At premature flowering levels below the threshold, yield and quality would not be expected to be affected significantly. Special management ...
