    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...
