Magnesium Deficiency in Groundnut

Magnesium Deficiency Symptoms

Mg Deficiency

As magnesium is not held tightly in soils, it is more susceptible to leaching losses from the root zone. Magnesium deficiency is most prevalent on sandy-textured soils, which are subject to leaching, particularly during seasons of excess rainfall. The predominant symptom is dark green veins with yellow areas between the veins(interveinal chlorosis). The bottom leaves are always affected first. The branches will be weak and prone to fungus attack As the deficiency becomes more acute, the symptoms progress up the plant. Chlorotic leaves generally turn red and then develop spotted necrotic areas .
