Which of the following practices is adopted to prevent 'greening' in Potato?

Correct option is B

· Correct answer: (b) Earthing up
· Earthing up is the practice of mounding soil around the base of the potato plant, which prevents exposure to sunlight and prevents greening of the tubers. Greening occurs when potatoes are exposed to sunlight, which produces solanine, a toxic compound.
Other options:
· (a) Closer Spacing: While closer spacing can affect plant growth, it does not directly prevent greening.
· (c) Early Sowing: Early sowing is not linked to preventing greening but can affect the growing season.
· (d) Normal Sowing: Normal sowing does not specifically prevent greening.
