Magnesium deficient plants are characterized by clear purple blotches on both the inner and outer surfaces of the petiole. As the deficiency becomes more serious, the blotches become more intensified. Older leaves turned bright yellow, at times leaving a green margin. Magnesium fertilization is very critical in soils with low inherent magnesium content. In such soils, if magnesium is not applied the plants will die and no suckers will be produced. More than 120 g magnesium oxide/clump per year was required by the plants to correct magnesium deficiency symptoms. An interim recommendation to correct magnesium deficiency and to maintain sufficient supply of magnesium is described.
