Tomato plant requires both macro and micronutrients for healthy

growth. Nutrients are provided using organic and chemical

sources. Nutrient requirement depends on fertility of the soil or

other alternative growth medium. Hybrid varieties of tomato take

more nutrients than local varieties.

Farm Yard Manure (FYM), Phosphatic and Potashic fertilizers are

applied in the beginning. Green manuring, farmyard manure,

oilseed cake like neem cake and bio-fertilizers provide essential

plant nutrients.

Introduction:

Nitrogen

• Leaves remains small, pale green to

yellow.

• Top leaves become yellowish green

with purple veins and stem becomes

thick and hard.

Management

•Application of nitrogenous fertilizers

based on soil test and if necessary

foliar sprays of nitrogen (urea).

Deficiency Symptoms Of Nutrients

Deficiency Symptoms of Nitrogen

• Seedling growth remains stunted with

delayed maturity.

• Leaves become dark green, inter

vain tissues becomes purple colored

from underside.

• Stems become slender, fibrous and

hard.

Management

• Application of Phosphatic fertilizers

based on soil test at the time of land

preparation.

Phosphorus

Deficiency Symptoms Of Phosphorous

• Seedlings stem becomes smaller, leaves become stunted and

spiked with short inter nodes and slow growth of leaf petioles

Potassium

Deficiency Symptoms Of Potassium

• Young leaves becomes wrinkled and

curled. Older leaves turned chlorotic and

bronzed. Leaf margins turn brown and

tissues between the veins dies off.

Management

• Application of Potashic fertilizers based

on soil test at the time of land

preparation.

• Iron deficiency found in calcareous soils or high carbonated

irrigation water where young leaves becomes chlorotic with pale

yellow mottling at the base of leaves and spreading upward.

Iron

Deficiency Symptoms of Iron

Management

• Spray 0.25 % Ferrous Sulphate

at weekly interval till new leaves

do not show iron deficiency

symptoms.

• Plants growth stunted with yellow inter

veinal mottling.

• Necrotic inter veinal areas occur in the

older leaves.

Management

• Spray 0.25 % Zinc Sulphate twice at

weekly intervals.

• Soil application of Zinc Sulphate @ 50

kg/ha is recommended.

Zinc

Deficiency Symptoms of Zinc

• Magnesium deficiency seen on lower

and older leaves. Leaf veins remain

green while leaf lamina turns yellow.

• Nitrogen deficiency increases the

Magnesium deficiency in soils.

Management

• Spray 0.5 % Magnesium sulphate twice

at weekly intervals.

• Check Nitrogen levels in the soil and

correct it if necessary.
