sulfur deficiency (  ) on flue-cured tobacco (Nicotiana tabacum (flue-cured type)) - 1402098

sulfur deficiency

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Damage
Description: Sulfur (S) deficiency is more likely on deep, coarse soils with low levels of organic matter when little or no fertilizer S has been applied. Since S may accumulate at lower soil depths, deficiencies normally occur during early growth before extensive root development. In contrast to N, the first symptom of S deficiency is a mild chlorosis of the upper leaves and bud. Unless the deficiency is alleviated, the entire plant will become chlorotic and flowering may be delayed. Another distinguishing difference between N and S deficiency is that the lower chlorotic leaves of S deficient plants are not lost by "firing" unless nitrogen is also deficient. Crops deficient is S show very little greening response to additional N until the S deficiency if corrected.
