Nitrogen

Nitrogen deficiency causes slow growth and paler leaves with reduced leaf area and rate of leaf production.

Leaf petioles short, thin and compressed, thin profuse roots and lesser number of suckers are produced due to      lack of N.

Phosphorus

The deficiency of P causes complete cessation of leaves elongation, leaf production is reduced, and marginal      chlorosis and premature death are caused.

P deficiency causes a blue or dark green coloration of leaves.

Potassium

Deficiency of potassium causes marked reduction in growth, interval profusely smaller, premature yellowing of      plant.

Purplish brown patches appear at the base of the petioles.

Calcium

Characterized narrow land of marginal chlorosis of leaves turning into necrotic fallow.

Splitting and curling of leaps edges.

Magnesium

Magnesium deficiency symptoms show green banding around the margin and next to the midrib.

Fruits do not ripen well and become tasteless.

Sulphur

Deficiency causes chlorosis and delaying of green colour in newly emerging leaves.

The heart leaf becomes white and leaf blades become very soft and tear easily.

Boron

Newly emerging leaves are malformed.

Plants show shunted growth.

Copper

Plants show overall droopy appearance with shortened intervals between petiole.

Size of leaves reduced.

Iron

Iron deficiency has been recorded in alkaline soils and is identified by interveinal chlorosis of young leaves.

Manganese

Marginal chlorosis of young leaves, which later turn brown.

Fruits with raised spots which are dark brown on black in color.

Zinc

Interveinal chlorosis of leaves with chlorotic stripes.

Leaves appear papery whole in colour.
