నత్రజని (N) లోపం

Class: పోషకాహార లోపాల
Common Name: నత్రజని (N) లోపం
Symptoms:

The main symptom is leaf chlorosis. Individual leaves will become pale and yellow. In cereals, yellow discoloration from the leaf tip creates a “V” shape.

In Short:

Nitrogen is a macronutrient that all plants need and is a key component in many important organic compounds such as amino acids, nucleic acids, and proteins.

Nitrogen uptake in plants occurs in the form of NO3− (ammonium nitrate), NH4+ from the soil, or N2 from the atmosphere with the aid of nitrogen-fixing bacteria.

All in all, the total content of nitrogen varies from 2 to 4% in dry plant matter.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
