#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.

#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.

▪️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

ዛሬ ጠዋት በጅማ ዩኒቨርሲቲ የተማሪዎች ተቃውሞ መነሳቱ ተሰማ።

ተማሪዎቹ ይህንን የተቃውሞው ድምፅ ያሰሙት በህዝባችን ላይ ግድያ ይቁም በሚል ምክንያት ሲሆን ተማሪዎቹ ቁርሳቸውን ሳይበሉ ነው ወደ ተቃውሞ እንደወጡ ለማወቅ የተቻለው።

ተቃውሞው እንዳይባባስ የፀጥታ ሀይሎች ጥረት አድርገዋል።
