For correct plant development, an everyday provide of plant vitamins particularly the important ones, is critical. Vegetation soak up a lot of components from the soil, air and water throughout their development interval, however not all of those are important.
Solely 16 components have been discovered to be important for all crops and 4 others have been discovered to be important for some crops.
Components for Plant Growth
For ingredient to be so categorised, it has to meet the
- A deficiency of the ingredient makes it
unattainable for the plant to finish the vegetative or reproductive stage of
its life cycle
- The deficiency
symptom of the ingredient in query will be prevented or corrected solely by
supplying that ingredient.
- The ingredient
will need to have a direct affect on the plant, and have to be instantly concerned in the
vitamin of the plant, fairly aside from its doable impact in correcting some
microbiological or chemical situation in the soil or tradition medium
Important ingredient like carbon, hydrogen, oxygen, nitrogen, phosphorus and sulphur are the weather of which proteins and therefore protoplasm are composed. The opposite ten components that are important for crops are potassium, calcium, magnesium, iron, manganese, molybdenum, copper, boron, zinc, and chlorine. The 4 components that are important just for some and not for all crops are sodium, cobalt, vanadium and silicon.

Sources of Nutrient for Plant Growth
The next components are derived:
air; carbon (C) as CO₂ (carbon dioxide);
the water: hydrogen (H) and oxygen (O) as H₂O (water);
the water: fertilizer and animal manure : nitrogen (N) a substantial quantity of
nitrogen can also be fastened by leguminous crops by root nodule micro organism
Macro and Micronutrients
Macronutrients are wanted by the crops in great amount, and giant portions must be utilized if the soil is poor in a number of of them. Inside the group of macronutrients, that are wanted for plant development in giant quantities, the first nutrient similar to nitrogen, phosphorus and potassium.
Whereas calcium, magnesium and sulphur are generally referred to as secondary vitamins as a result of their secondary significance In plant vitamin.
In distinction with macronutrients, micronutrients or hint components are required in solely minute quantities for proper plant development and must be added in very small portions after they can’t be offered by the soil.
Features of Vitamins in Plant Growth
is the motor of plant development. It makes as much as 1 to 4 p.c of dry matter of
the plant. It’s taken up from the soil in the type of nitrate (NO₃) or

These are iron (Fe), manganese (Mg), Zinc (Zn), copper (Cu), molybdenum (Mo), chlorine (Cl) and boron (B). They’re a part of the important thing substances in plant development and are comparable with nutritional vitamins in human vitamin. Being taken up in minute quantities, their vary of optimum provide may be very small.
