calcium deficiency (  ) on burley tobacco (Nicotiana tabacum (burley type)) - 1440092

calcium deficiency

Host: burley tobacco (Nicotiana tabacum (burley type) L.)
Descriptor: Damage
Description: Ca deficiency in burley tobacco is not common but sometimes occurs when soil exchange capacities and/or Ca saturation levels are low. Such conditions are most likely to occur in sandy soils with low pH. Ca deficiency symptoms first appear in the upper or youngest leaves because Ca is immobile within the plant. Typically, symptoms begin in the bud with the development of a pale green color, followed by rolling and downward curing of the new leaves. As the deficiency becomes more acute, dead or necrotic areas develop at tips and along edges of leaves. Under extreme deficiencies, the terminal bud eventually dies. Lower and middle leaves of Ca deficient plants may develop a darker a darker than normal green color.
