Potassium deficiency-Banana

Symptoms
Symptoms of potassium deficiency are visible on older leaves first. Leaf margins are scorched with a well-defined yellow seam running along the necrotic area.

Reasons
Potassium deficiency Manganese and phosphorus deficiency also result in chlorosis followed by necrotic zones starting from the leaf margin. However, Mn deficiency is visible on younger leaves first. Magnesium deficiency causes interveinal chlorosis with necrotic zones later, but these are spread over the whole leaf area.

Symptoms
Symptoms of potassium deficiency are visible on older leaves first. Chlorosis starts from the intercostal areas of the leaf tip, but the chlorotic zones coalesce and the whole leaf tip becomes yellow. Later, it turns dark brown and dies off. Basal parts of the leaves remain green for a longer time.

Reasons
Potassium deficiency Manganese and phosphorus deficiency also result in chlorosis followed by necrotic zones, but these start from the leaf margin, not from the leaf tip. Furthermore, Mn deficiency is visible on younger leaves first. Magnesium deficiency causes interveinal chlorosis with necrotic zones later, but these are spread over the whole leaf area and are not concentrated on the leaf tip.
