Deficiency symptoms of Nitrogen:

1. Deficiency of nitrogen interferes with protein synthesis and hence all forms of growth are affected.

2. An early symptom is yellowing of leaves and development of chlorosis.

3. Older leaves turn light brown in colour and gradually dry.

4. Flowering is delayed or completely suppressed.

Deficiency symptoms of Phosphorous :
The deficiency of phosphorus causes :

1. disruption of general metabolism

2. abnormalities in the shape and size of chloroplast.

Deficiency symptoms of Sulphur :

1. Deficiency symptoms first appear in young leaves.

2. They become reduced, chlorotic followed by anthocyanin pigmentation in certain species.

3. Root system becomes extensive and stems become hard and woody.

Deficiency symptoms of Potassiam :

1. Deficiency symptoms are first observed on the older, lower leaves. Spots of dead tissue on older leaves are seen. 

2. Potassium deficiency in cereal crops develop weak stalk. These plants easily bent to the ground by wind or rain.

Deficiency symptoms of Calcium :

1. Calcium deficiency brings about decomposition of root epidermis, roots become mucous, the growing zone and lateral roots rapidly die off.

2. Its deficiency terminates growth of meristematic regions.

3. Margins of younger leaves show chlorosis which become nacrotic.

4. Twig or stalk just below the tip and seed head is often unable to stand erect.

Deficiency symptoms of Magnesium :

1. Extensive interveinal chlorosis of the leaves resulting in defoliation;

2. Yellowing of the leaves start from basal to younger ones;
