    Influence of Quadris fungicide and foliar fertilizer brands on the holdability of flue-cured tobacco

    WHALEY W.T.; JERNIGAN C.H.
    North Carolina Department of Agriculture and Consumer Services-Agronomic Division, Raleigh NC USA
    Over the past decade, tobacco farming in North Carolina has transitioned from many growers with relatively small acreage to fewer growers with more acreage. As a result, growers have experimented with various products in hopes of promoting holdability of ...

    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 blending ...
