Nitrogen fertilisation is applied for growth, but its excess

Answer: Option B

Nitrogen fertilization is applied for growth, but its excess delays maturity.
Nitrogen Fertilization Increases Root Growth and Coordinates the Root-Shoot Relationship in Cotton. The root system plays an important role in the growth and development of cotton, and root growth is closely related to shoot growth, both of which are affected by N availability in the soil.
Excessive nitrogen causes fruiting plants to produce relatively more foliage, reducing their fruit production and delaying fruit maturity.
