🔰 Role of nutrients and their deficiency Symptoms 🔰
#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.
#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 (Agricultureexamslibrary) Phosphorus is called " key of life "
▪️Deficiency imparts dark green colour in leaves.
▪️Later develops red purple colourration.
#Disease
▪️Sickle leaf diseases.
#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.
#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.
#Magnesium
▪️ Essential constituent of chlorophyll.
▪️ Magnesium is a constituent of chlorophyll.
▪️Chlorosis between veins.
#Disease
▪️Sand -drown disease of tobacco.
#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.
#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.
#Copper
@agricultureexams2020
▪️Compound of plastocyanin.
▪Essential for photosynthesis/ respiration.Agriexams library
▪️Dieback and reclamation disease of cereals.
#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.
#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.
