Transcript RLO Nutrient Management in Tomato Nursery

Introduction:
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.
Deficiency Symptoms Of Nutrients
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 Nitrogen
Phosphorus
• 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
Deficiency Symptoms Of Phosphorous
based on soil test at the time of land
preparation.
Potassium
• Seedlings stem becomes smaller, leaves become stunted and
spiked with short inter nodes and slow growth of leaf petioles
• 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
preparation.

Deficiency Symptoms Of Potassium
Iron
• 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.
Management
• Spray 0.25 % Ferrous Sulphate
at weekly interval till new leaves
do not show
iron deficiency
symptoms.
Deficiency Symptoms of Iron
Zinc
• 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.
Deficiency Symptoms of Zinc
Magnesium
• 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.
