Symptoms
Chlorosis starts in young leaves and proceeds to the older leaves with ongoing deficiency. First leaves show chlorosis in the intercostal fields, later on they are uniformly light green or yellow. Stems, petioles and leaves often turn purple.
The leaves are stiff and curl inwards.
Reasons
Sulphur deficiency on leaves of young plants
Sulphur deficiency is similar in appearance to nitrogen deficiency, however it begins in younger leaves because sulphur is not as mobile as nitrogen within the plant.
Symptoms
Chlorosis starts in young leaves and proceeds to the older leaves with ongoing deficiency. First leaves show chlorosis in the intercostal fields, later on they are uniformly light green or yellow. Frequently, brassica crops develop longer leaf stems and narrow spoon-like malformed leaves.
Reasons
Sulphur deficiency on young plants
Sulphur is required in relatively high quantities in brassicas for good growth and crop quality. Its uptake can be restricted with increasing N supply.
Sulphur deficiency might be confused with nitrogen deficiency, however it begins in younger leaves. Interveinal chloroses caused by Magnesium deficiency look similar, too.
