Plant nutrition

 Plants exploit many elements from soil water and air for their growth but all the exploited elements do not participate in the nutrition of the plant.The elements that participate in the nutrition of the plant are called nutrition.

 Essential Nutrients – In the absence of nutrients, plants cannot complete their life cycle successfully, hence they are called essential nutrients.

 Carbon Hydrogen Oxygen Nitrogen Phosphorus Sulfur Protein and Protolajema are the ingredients.

 In addition to these six elements, 14 elements are calcium, magnesium, potassium, iron, manganese, molybdenum, copper, boron, chlorine, sodium, cobalt, and silicon.

Essential nutrients are divided into three parts

plant nutrition

[A] main nutrient 

[B] gourd nutrients 

[C] Micronutrients

Main Nutrients – Nitrogen phosphorus and potassium are the main nutrients.

Minor nutrients – Calcium magnesium, sodium and sulfur etc.

Micronutrients – Zinc Iron Copper Manganese Boron Molybdenum Chlorine is Benedium and Cobalt 

  • Phosphorus is also a potassium regulator balanced in nitrogen control in plants. 
  • Nitrogen plays an active part in the structure of chlorophyll amino acids of plants, vitamin nucleic acid, protein amides and protoplasm.

Nitrogen deficiency leaves white spots between the leaves of plants.

  • Leaves turn white
  • Leaves sometimes melt 
  • Most of the fruits in fallow trees fall before ripening. 
  • In the grain crops, the lower leaves of the plants first start drying up.
  • Gradually the top leaves dry up

Phosphorus plays an important role in the conversion of energy

It neutralizes the harmful effects of nitrogen.

  •  Increases the number and size of glands in the roots of leguminous crops. 
  • Increases ability of plants to withstand pest attacks

plant nutrition

Lack of phosphorus leads to darker color of plants 

  • The leaves below turn yellow and dry 
  • Plant growth stops and due to the absence of it, the grain of corn is not formed. 
  • Lemon leaves cause necrosis 
  • Vegetable growth stops due to its deficiency 
  • Spots appear inside the potato 

*Potash is required for the following daily work in plants

plant nutrition 

  • It helps in the transfer of carbohydrates. 
  • It increases the formation of sugar and starch in the leaves. 
  • It is helpful in many types of oxidation and reactions as an iron carrier. 
  • Symptoms appear in plants lacking potassium 
  • The lack of it first shows the maturity of plants on old leaves.

Lack of potash in cotton causes yellow white pigmentation disease

Stains appear in between veins of plant leaves of tobacco

Due to the lack of calcium, sometimes green rashes appear on the leaves and the plants remain small.

  • Magnesium is a component of chlorophyll 
  • No plant can be green without it
  • It helps in transfer of sugars [start] in plants. 
  • Magnesium deficiency symptoms appear in old leaves and gradually have an effect on new leaves.  
  • In potato plant, yellow spots of irregular shape are produced on the crispy leaves.

Sulfur is also helpful in the manufacture of chlorophyll

plant nutrition* 

Sulfur is found in mustard oil

  • Sulfur leads to more growth of glands in the roots of alfalfa

Sulfur deficiency causes TEA YELLOW disease in tea 

  • Its decrease in lemon slows growth  
  • The color of the vegetables turns yellow
  • Potato leaves growth stops

Iron is an essential element for the manufacture of chlorophyll but not a part of chlorophyll, nitrogen is helpful in protein synthesis by plants. 

  • Nitrate degrades in plants

Iron deficiency is a common effect of green deficiency which leads to new parts of the plants before 

  • Many fruits fall undercooked 
  • Lemon, stains of inanimate tissue appear on leaves in square trees. 

Manganese helps in the manufacture of chlorophyll 

  • It helps in the denaturing of nitrate.  
  • It acts as a catalyst in oxidation degradation. 
  • In the absence of manganese, small green spots are found in the leaves of the leaves. 
  • Tissue in the plant causes rotting disease

* plant nutrition

Due to lack of manganese, brown spots in oats, the signs of sugar cane, first appear on new leaves.

Due to zinc deficiency, there is an outbreak of disease called Khaira in paddy plants, white bud gets the disease in maize.

Poisonous disease in tung trees causes balan leaf disease in lemon and also balan leaf disease in mangoes.

Copper also causes the self-healing process of plants.

It prevents chlorophyll destruction. 

  • It is helpful in indole acetic acid synthesis in plants.  
  • In its use, outbreak of mildew disease in plants is less.  
  • Helpful in vitamin A 
  • Copper deficiency in paddy crops leads to a disease called Reclamation 
  • Tip of leaves turns white 
  • Tillers weaken  
  • The leaves of lemon-grown plants become ugly.
  • Gum-like sticky substance accumulates on the bark of the fruit
  • Beron helps in nitrogen exploitation by plants.  
  • Pollen and is helpful in breeding women 
  • This flower affects fruit and seed production.  
  • In Barron leguminous plants serves as a root glands for symbiotic nitrogen fixation

Boron first effects on new leaves of plants. 

  • Due to its deficiency, the leaves become thick and die. Roots do not grow, become thick, twists, flowers and fruits do not take place before fruits are ripened, internal melting in beetroot in apple, internal cork in turnip, complete internal pore in the turnip, disease, etc.
  • Molybdenum nutrient is useful in plants

 It is necessary for the positioning of free nitrogen by the Azotobacter and Rhizobium bacteria. 

  • It is essential in the synthesis of vitamin C.

* plant nutrition

Molybdenum nutrient deficiency causes plant symptoms. Harima in between leaves of plants leads to inferiority.

  • Leaf color is yellow
  • The leaves of citrus species turn yellow due to this disease called YELLOW SPOT.

Chlorine increases the graying stains in plants 

  • Cation maintains equilibrium in cell juices and is a constituent of anthoscience.

* plant nutrition

Symptoms of chlorine deficiency in plants The lower wives of tomato plants wither away.  

  • It leads to harm 
  • The special smell of pattaroli ceases 
  • Maximum leaves of the plant die 
  • Plants do not produce fruit

* plant nutrition

Cobalt is required for elemental nitrogen fixation by Rhizobia. 

  • This vitamin B12 which is required in the manufacture of hemoglobin

* Vanadium is essential for Hari algae 

  • Helps dress in Azotobacter 
  • Asparagus is essential for rice and corn 
  • It is required for the biological oxidation degradation reaction. 
  • Sodium beet is required 
  • It helps in opening stomata in plants.
  • Silicone cucumber is required for cucumber rice
