Question

Name at least five different deficiency symptoms in plants. Describe them and correlate them with the concerned mineral deficiency.

Answer 1

The five main deficiency symptoms arising in plants are:

• Chlorosis: Chlorosis or loss of chlorophyll leads to the yellowing of leaves. It is caused by the deficiencies of nitrogen, potassium, magnesium, sulphur, iron, manganese, zinc, and molybdenum.
• Necrosis: Necrosis is the death of plant tissues as a result of the deficiencies of calcium, magnesium, copper, and potassium.
• Inhibition of cell division: Inhibition of cell division is caused by the deficiencies of nitrogen, potassium, sulphur, and molybdenum.
• Delayed flowering: Delayed flowering is caused by the deficiencies of nitrogen, sulphur, and molybdenum.
• Stunted plant growth: Stunted plant growth is a result of the deficiencies of copper and sulphur.
