Nutrient Application in TPS Nursery

• Media Preparation: Sterilized garden soil + Well rotten farm yard

manure (FYM) in 1:1 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

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

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.

Role of Nutrients:

Deficiency Symptoms of Calcium

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:

Deficiency Symptoms Of magnesium

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. Deficiency Symptoms Of iron

Deficiency Symptoms Of Sulphur

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.

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.
