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.

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.
