    Establishing application protocols for poultry litter and feather meal in organic Burley tobacco production

    SUCHOFF D.H.; VANN M.C.; FISHER L.R.; WHITLEY D.S.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Information on nutrient management in organic Burley tobacco is limited. Unlike conventional nitrogen (N) sources, which are readily available for plant use upon application, organic N fertilizers require microbial mineralization to become plant...

    Flue-cured tobacco tip leaf yield, quality, value, and color distribution as influenced by cultivar and harvest schedule

    VANN M.C.; FISHER L.R.; INMAN M.D.; WHITLEY D.S.; SEAGROVES R.W.; BARNES K.
    North Carolina State University, Department of Crop & Soil Sciences, Raleigh, NC, U.S.A.
    Changes in consumer preference and export strategy strongly influence the buying practices of tobacco leaf dealers and cigarette manufacturers. In current times, a dark-colored (orange to red) style of flue-cured tobacco is preferred over a brighter...

    Effect of organic nitrogen source and application rate on the yield and quality of flue-cured tobacco

    VANN M.C.; FISHER L.R.; WHITLEY D.S.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, U.S.A.
    Organic carbon-based sources of nitrogen, such as livestock waste or by-products, have not been recommended for the production of flue-cured tobacco. At present, there is significant demand for organically produced leaf, and in these systems the use...

    Effect of organic nitrogen source and application timing on the yield and quality of flue-cured tobacco

    MASON J.H.; VANN M.C.; FISHER L.R.; WHITLEY D.S.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, U.S.A.
    Mineralization rates of organic nitrogen are extremely dependent upon factors such as soil pH, temperature, and moisture. Flue-cured tobacco is extremely sensitive to nitrogen availability; therefore, many questions have been presented regarding...

    Evaluation of non-tobacco labeled herbicides for late season application

    WHALEY W.T.; VANN M.C.; FISHER L.R.; WHITLEY D.S.
    North Carolina State University, Dept. of Crop Science, Raleigh, NC, U.S.A.
    Recently, viable seed from various weed species has been found in tobacco exports from the United States, initiating great concern in foreign markets and a zero tolerance policy. University specialists believe the majority of weed seed contamination...

    Conveyor use for suckercide application in North Carolina Burley tobacco production

    VANN M.C.; FISHER L.R.; WHITLEY D.S.
    North Carolina State University, Department of Crop Science, Raleigh, NC, U.S.A.
    In 2011, conveyors were introduced to the US market for use in chemical sucker control programs. Due to focused application and coarse droplet size, it was initially thought that conveyors might assist in reducing maleic hydrazide (MH) residues,...
