Cabbage - Chlorosis

Symptoms
Symptoms of magnesium deficiency start on older leaves. Chlorosis between the veins progresses from the margin to the middle of the leaf. First the affected areas turn yellow-green, later color changes to orange or red. The small veins also become chlorotic, but the bigger ones remain green and white respectively. The interveinal zones curl up. Growth reduction is only slight when deficiency is moderate, but increases with severe deficiency.

Symptoms
Affected plants are not reduced in leaf size. Head forming is inhibited, plants show a loose habitus with rather elongated leaf shape. Leaf margins of young plants are more serrated than usual. >Older leaves turn yellowgreen.

Magnesium deficiency made worse by

  • Sandy soils
  • Acidic soils
  • Potassium rich soils
  • Soils receiving high potash applications
  • Cold wet periods

Magnesium is important for

  • Increases photosynthetic activity maintaining good growth for high yields
  • Improves storage quality
