It is the pre-harvest practice aimed at hardening the skin of the tubers which provides the best quality seed tubers.

Nitrogen is the most essential element for plant growth and it is the common element for glycoproteins, Nucleic acids and Chlorophyll.
Nitrogen plays a critical role within the plant to ensure energy is available when and where the plant needs it to optimize yield.

AICRP is the All India Coordinated Research Project on sugarcane that was set up in 1970 - 1971.

China is the top country in wheat production. About two-thirds of the total wheat production came from the North China plain. As per the reports, total wheat production in china was 1,34,250 thousand tons in 2020, which is 20.66% of the world's wheat production.

CAM (Crassulacean acid metabolism), is a photosynthetic adaption to periodic water supply, in the plants occurring in Arid regions.
