Effect of Nitrogen on Sesame

Nitrogen is the main component of protein, chlorophyll, enzyme, nucleic acid, vitamin and alkaloid. The nitrogen supply is normal, the plant growth is luxuriant, the yield is high and the quality is good. The excessive or late application of nitrogen will cause excessive growth and lodging, and the green ripening period will be postponed at maturity. The disease resistance was weakened, which led to the decrease of yield and quality. On the contrary, the supply of nitrogen is sufficient, the formation of protein and chlorophyll in the body is blocked, and the growth and development is slow. The plant is short, the leaves are small, and the leaves turn yellow, even withered, aging before old age. Therefore, rational application of nitrogen fertilizer is one of the measures to increase production.
