Nutrient Application in TPS Nursery

Nutrient Application in TPS Nursery

• Media Preparation Sterilized garden soil Well
  rotten farm yard manure (FYM) in 11 ratio. Top
  most layer of bed (2-3 cm) is prepared from
  finely sieved FYM. Total height of seed bed 10
  cm.
• Sowing Depth 0.5 cm and Distance between 2 rows
  10 cm
• 10 gm Nitrogen, 30 gm Phosphorous and 10 gm
  Potash is applied to 100 kg of media. Out of
  this, 5 gm N, 8 gm P2O5 and 10 gm K2O per square
  meter of bed is applied as basal dose.
• 4-5 foliar spray of 0.1 urea are given on
  alternate days after 15 days of sowing.

Role of Nutrients
Nitrogen (N) Stimulates plant growth as a
component of chlorophyll. Increases tuber protein
content. Deficiency Symptoms Reduced seedling
growth and pale leaves at nursery stage. Excess
Delayed maturity and excessive shoot
growth. Phosphorus (P) Encourages root and tuber
development. Deficiency symptoms Stunted plants
growth, yellowing of older leaves, small dark
green younger leaves.
Deficiency Symptoms Of Nitrogen
Deficiency Symptoms Of phosphorous
3
Role of Nutrients
Potassium (K) Stimulates leaf and tuber growth,
increases resistance to diseases and improves
tuber quality. Deficiency symptoms Potassium
deficiency retards nitrogen uptake, slow plant
growth reduces quality and quantity of yield,
poor disease resistance. Typical symptoms are
necrosis of leaf margins, premature leaf
senescence
Deficiency Symptoms Of potassium
4
Role of Nutrients
Calcium (Ca) Calcium helps in cell division,
cell elongation and cell wall development,
nitrate uptake, enzyme activity and starch
metabolism. Deficiency symptoms stunted root
growth, leaf growing tip deformation and
reduced quality. Typical symptoms are yellow
curled chlorotic upper leaves and tip burns.
Deficiency Symptoms of Calcium
5
Role of Nutrients
Magnesium (Mg) Magnesium acts as a carrier of
phosphorus and constituent of chlorophyll. It is
necessary for enzyme activation and nutrient
uptake. Deficiency symptoms Leaves get
yellow-brown, wilt and die Stunted plants.
Excess Results in reduced calcium uptake and
symptoms similar to calcium deficiency.

Role of Nutrients
Sulphur (S) Sulphur application reduces soil pH
and thus severity of common powdery scab
disease. Deficiency symptom Stunted growth,
reduction in leaf number. Leaves turn pale green
or yellow. Iron (Fe) is important for
chlorophyll synthesis. Deficiency symptoms They
first appear on the youngest leaves. Inter veinal
chlorosis with green veins is observed. In
severe deficiency, the entire leaf becomes
chlorotic.

Role of Nutrients
Manganese (Mn) It is necessary in
photosynthesis. Deficiency symptoms Black or
brown spots on younger leaves leaves
yellowing. Boron (B) it has important role in
cell wall formation, germination, elongation of
pollen tube and metabolism transport of sugars.
Deficiency symptoms Death of growing buds,
plants bushy with shorter internodes. Leaves
thicken and roll upward leaf tissue darkens and
collapses.

Role of Nutrients
Copper (Cu) Copper influences metabolism of
nitrogen and carbohydrates. Deficiency symptoms
Young leaves become flaccid and wilted, terminal
buds drop and leaf tips become necrotic.
