Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type)
Description: Nitrogen (N) deficiency may result in retarded growth and leaves with a pale green color. Lower leaves yellow prematurely, are smaller, and tend to "fire" or dry up. The stalk is short and slender, leaves tend to be more upright than normal, and flowering is delayed. Premature flowering may result if certain stresses such as low temperatures or extremeness in soil moisture interfere with N uptake and use. Symptoms of deficiency usually appear first on the sandier areas of a field after excessive rain or irrigation even when adequate N fertilizer had been previously applied.
