 |
 |
| Deficiency Symptoms | 1. The yellowing in nitrogen deficiency is uniform over the entire leaf including the veins.
2. Younger leaves turn darker green, older leaves remain yellow. 3. Upward cupping of deficient when severs. |
1. The symptoms first develop on older leaves showing some necrotic spots and plants are dwarfed or stunted.
2. Plants develop a distinct purpling of the stem, petiole and the undersides of the leaves. 3. Lower leaf surface grey-green. 4. Leaflets roll upward, severely if a deficiency is severe. |
1. Since potassium is very mobile within the plant, symptoms only develop on young and full-sized leaves in the case of extreme deficiency.
2. As the deficiency progresses, most of the interveinal area becomes necrotic, the veins remain green and the leaves tend to curl and crinkle. 3. Leaves take on a scorched appearance with black pigmentation and necrotic (dead tissue) edges. |
1. The calcium-deficient leaves show necrosis around the base of the leaves.
2. The very low mobility of calcium is a major factor determining the expression of calcium deficiency symptoms in plants. 3. This ultimately results in the margins of the leaves grow more slowly than the rest of the leaf, causing the leaf to cup downward. |

 |
 |
 |
| Deficiency Symptoms | 1. These leaves show general overall chlorosis.
2. The yellowing is much more uniform over the entire plant including young leaves. 3. The reddish colour often found on the underside of the leaves. 4. Leaflet yellowing is uniform and general. |
1. The Mg-deficient leaves show advanced interveinal chlorosis.
2. The symptoms generally start with mottled chlorotic areas developing in the interveinal tissue. 3. Symptoms appear first on young mature leaves. |
1. Iron has low mobility, iron deficiency symptoms appear first on the youngest leaves.
2. Iron deficiency is strongly associated with calcareous soils, anaerobic conditions, and it is often induced by an excess of heavy metals. 3. Growing point and young leaves become yellow or in extreme cases, white. Usually not accompanied by necrosis. 4. Veins and leaflet ends remain green. |
1. These boron-deficient leaves show light general chlorosis.
2. Boron deficiency results in necrosis of meristematic tissues in the growing region, leading to loss of apical dominance and the development of a rosette condition. 3. The leaves are unusually brittle and tend to break easily. |
1. The leaves show light interveinal chlorosis developed under a limited supply of Mn.
2. The early stages of the chlorosis induced by manganese deficiency are somewhat similar to iron deficiency. 3. Browsing spotting occurs on leaflets, especially along larger veins and mid-ribs. |
