    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....

    Boron (B) is an essential micronutrient for optimum plant growth of flue-cured tobacco and is required in trace amounts (<1.0 lb B/acre). Since use of premium tobacco fertilizer grades that contain trace amounts of B are not typical in today’s...

    Chloride application: effects to nutrient assimilation, agronomic performance, and cured leaf chemistry of flue-cured tobacco

    VANN M.C.(1); FISHER L.R.(1); INMAN M.D.(1); HARDY D.H.(2)
    (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-) application in excess of 34 kg ha-1 has generally been discouraged in the production of U.S. flue-cured tobacco, due to the negative effects the nutrient can have on cured leaf yield, quality, and smoke sensory. However, fertilizer...

    The effect of chloride application rate to the yield, quality, and chemical constituents of flue-cured tobacco

    PACE C.R.(1); VANN M.C.(1); FISHER L.R.(1); SEAGROVES R.(1); HARDY D.H.(2)
    (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-) application rates that exceed 33.6 kg/ha are generally discouraged in the production of flue-cured tobacco due to the negative effects the micronutrient can impart to yield, quality, and smoke flavor/aroma. Despite the negative effects...
