Nitrogen is an essential macronutrient for plants and plays a critical role in plant growth and development. Nitrogen is a key component of chlorophyll, the pigment that allows plants to absorb light energy and perform photosynthesis. Nitrogen is also a key component of amino acids, which are used to build proteins, and nucleic acids, which are used to create DNA and RNA.
Adequate nitrogen supply is essential for the growth of leaves, stem and roots. Nitrogen is also important for the formation of chlorophyll, which is essential for photosynthesis, and the production of protein, which is necessary for the growth and development of the plant.
A deficiency in Nitrogen can result in a stunted growth, yellowing of the leaves, and a reduction in the number of leaves. The older leaves may appear yellow, while the newer leaves may appear pale green or yellow. This is because the plant is not able to produce enough chlorophyll to support the growth of new leaves.
On the other hand, an excess of Nitrogen can lead to lush green foliage, but at the expense of the development of flowers and fruits, and can also cause an overproduction of leaves that can lead to a weaker stem and an increased risk of disease.
It’s important to keep in mind that the right amount of Nitrogen is essential for the proper growth and development of plants, and it’s important to regularly
