Q1: Pick out the wrong statement.

ANS:C - Application of large excess of potassic fertiliser in soil increases the valuable carotene in fruits and vegetables.

The wrong statement is: Application of large excess of potassic fertilizer in soil increases the valuable carotene in fruits and vegetables. Potassium (K) is an essential nutrient for plant growth and is often included in fertilizers. While potassium plays a crucial role in various physiological processes in plants, such as water regulation, enzyme activation, and disease resistance, there is no direct evidence to suggest that the application of large excesses of potassic fertilizer specifically increases the valuable carotene content in fruits and vegetables. Carotene is a precursor to vitamin A and is responsible for the orange coloration in many fruits and vegetables. It is primarily synthesized by plants through photosynthesis and is influenced by various factors such as genetics, environmental conditions, and soil nutrient availability. While potassium may indirectly affect overall plant health and vigor, its direct influence on carotene content in fruits and vegetables is not well-established. Therefore, the statement suggesting that the application of large excesses of potassic fertilizer increases the valuable carotene in fruits and vegetables is not supported by current scientific evidence.
