Question

Deficiency of potassium causes :

• A. leaves to die out early
• B. decrease in plant strength
• C. greying of leaves
• D. both $A$ and $B$

Answer 1

The correct option is B decrease in plant strength

Typical symptoms of potassium deficiency in plants include brown scorching and curling of leaf tips as well as chlorosis (yellowing) between leaf veins. Purple spots may also appear on the leaf undersides. Plant growth, root development, and seed and fruit development are usually reduced in potassium deficient plants.

Thus, an overall decrease in plant strength takes place.
