Show Answer
Answer:
Correct Answer: A
Solution:
- Deficiency symptoms of nitrogen and potassium are typically visible first in senescent leaves. This is because both nitrogen and potassium are mobile nutrients within the plant, meaning they can be translocated from older leaves to younger, actively growing parts of the plant when there is a deficiency. As a result, the older, or senescent, leaves show the deficiency symptoms first.
