Tobacco - Chlorosis

Symptoms
Sulfur deficiency symptoms are first visible on younger leaves. The midrib becomes yellow, and this chlorosis spreads throughout the whole leaf. The leaf may turn completely whitish. Necrosis does not occur, even at severe deficiency.

Reasons
Sulfur deficiency Nitrogen deficiency also leads to leaf chlorosis, but this starts on older leaves and is followed by necrosis. Iron deficient plants show lanceolate leaf shape and chlorosis on younger leaves, but in contrast to S deficiency, the leaf veins remain green.

Tobacco - Deformation

Symptoms

The leaf shape is more narrow, and the leaf tips are bent downwards. Necrosis does not occur, even at severe deficiency. Growth of the whole plant is clearly stunted.

Reasons
Sulfur deficiency (right plant) Nitrogen deficiency also leads to leaf chlorosis, but this starts on older leaves and is followed by necrosis. Iron deficient plants show lanceolate leaf shape and chlorosis on younger leaves, but in contrast to S deficiency, the leaf veins remain green.

Sulfur deficiency made worse by

Acidic soils
Light, sandy soils (leaching)
Low organic matter
Poorly aerated soils (waterlogged soils
) Areas with low industrial emissions

Sulfur is important for

Green foliage and healthy growth
More effective use of nitrogen by the crop
