#Nitrogen

▪️Impart green colour to plant encourages vegetative growth

▪️ Nitrogen is essential constituent of protein

▪️ Constituent of Protoplasm of chlorophyll and coenzyme.

▪️ Play important role in 

synthesis of auxin

#Deficiency

▪️ Lower leaves become yellow and dries.

▪️V shaped chlorosis on older leaves or yellowing at tip.

#Disease

 ▪️Starvation disease due to nitrogen deficiency.

▪️Buttoning in cauliflower.

#Potassium

▪️Most essential function of K+ is stomata regulation.

▪️Provides disease resistance in plants.

▪️Cofactor for enzymes.

▪️Formation and translocation of Sugars.

▪️Helps in chlorophyll formation.

#Deficiency

▪️Spot of dead tissue at tips.

▪️Scorching and burning on margins of autumn leaves.

#Disease

▪️Rottle/ dieback disease.

Role_of_nutrients_and_their_deficiency_Symptoms.

#Phosphorous

▪️Increase the disease resistance.

▪️ Enhance new cell formation and necessary for root development. 

▪️Required for grain formation and maturity of grains.

▪️Phosphorus is essential constituent for nucleic acid and phytin.

▪️Most essential functions are energy storage and transfer energy act as "energy currency".

#Deficiency

▪️Due to deficiency of single element the life cycle of plant can't be completed hence  Phosphorus is called " key of life "Agriclass

▪️Deficiency imparts dark green colour in leaves.

▪️Later develops red purple colourration.

#Disease

▪️Sickle leaf diseases.

#Magnesium

▪️ Essential constituent of chlorophyll.

▪️ Magnesium is a constituent of chlorophyll.

▪️Chlorosis between veins.

#Disease 

▪️Sand -drown disease of tobacco.

#Calcium

▪️ It is constituent of cell wall

▪️ Calcium is a mobile in plants and deficiency symptoms appear on Meristem tip portion.

# Deficiency

▪️ Terminal bud die

 #Disease 

▪️Tip hooking.

▪️ Blossom end rot of tomato(BER).

▪️Popping in groundnut.

#Sulphur 

▪️ Sulphur oxidizing Bacteria is Thiobacillus. 

▪️Sulphur is essential for oil seed and pulses because it improves oil content and protein content in oil seeds and pulses, respectively.

#Disease

▪️Akiochi disease of rice due to Excess of hydrogen sulphide.

 ▪️Tea yellow disease of tea.

#Iron

▪️Fe is the component of nitrate reductase. 

▪️Required for nitrogen fixation.

 ▪️During respiration act as O2 carrier.

#Deficiency

 ▪️Interveinal complete chlorosis.

▪️Scorching of leaf margin.

▪️Yellowing of iron chlorosis in groundnut.

#Copper

▪️Compound of plastocyanin.

▪Essential for photosynthesis

▪️Dieback and reclamation disease of cereals.

#Manganese 

▪️Formation of chlorophyll.

▪️Co-factor of enzyme.

▪️Mn toxicity causes crinckle leaf of cotton.

#Deficiency 

▪️Dead spot on leaves.

#Desease

▪️Marsh spot of pea.

▪️Pahala blight of sugarcane.

#Molybdenum

▪️Mo: absorbed as molybdate MoO4-2 forms.

▪️Mo  is important component of enzyme: Nitrate reductage.

▪️N-fixation in pulses.

▪️Whiptail of cauliflower is due to deficiency of Mo.

▪️Mo is required for carrot & raphanus for sweetness.

#Boron

▪ Necessary for Pollen germination.

▪️Boron is the only non-metal element among the micronutrient.

▪️It is necessary for translocation of Sugars and is involved in reproduction and germination of pollen.

#Disease : due to deficiency 

▪️Browning of cauliflower is caused by Boron deficiency.

▪️Top sickness of tobacco.

▪️Fruit cracking of tomato.

▪️Hard fruit of citrus.

▪️Hen and chick disease of grape.

#Zinc 

▪️In plants it is required for biosynthesis of hormones.

▪️Zn deficiency causes-

-White bud of maize.

-Khaira disease of rice.

-Little leaf of cotton.

-Mottled leaf of citrus. 

-Rosette formation.

#Cobalt 

▪️It is component of Vitamin B

▪️It is essential for formation of type of hemoglobin in N-fixing nodule tissue known as leghaemogloin.

▪️Act as O2 carrier in roots.

▪️Also known as animal protein factor
