How does cobalt affect plant growth?

Cobalt is necessary for the processes of stem growth, elongating the coleoptiles, and expanding leaf discs. It is a critical element needed for a plant to reach maturity and for healthy bud development. Although Co is an essential nutrient, excessive over doses result in a variety of adverse responses (Nagpal, 2004).

What are the 5 common deficiency symptoms in plants?

What are the 3 most common nutrient deficiencies in plants?

The nutrients most commonly deficient in plants are phosphorus, nitrogen, and iron. Phosphorus can be present in the soil, but in quantities too small to be taken up effectively. Nitrogen might be present, but in a form that cannot be used by plants. In alkaline soils, some plants are unable to take up iron.

What are the symptoms of iron deficiency in plants?

The primary symptom of iron deficiency is interveinal chlorosis, the development of a yellow leaf with a network of dark green veins. In severe cases, the entire leaf turns yellow or white and the outer edges may scorch and turn brown as the plant cells die.

What are the signs of nickel deficiency in plants?

One common Ni deficiency symptom across plant species is the necrosis of leaf tips due to the accumulation of urea to toxic concentrations. For non-woody plants, deficiency symptoms can also include chlorosis of young leaves, reduced leaf size, and less upright leaf growth.
