Which nutrient is represented by the symbol "K" in plant nutrition?

• A. Nitrogen
• B. Phosphorus
• C. Potassium
• D. Calcium

Answer: (C)

In plant nutrition, the symbol "K" represents potassium, which is one of the essential macronutrients required for plant growth and development. Potassium plays a vital role in various physiological processes, including enzyme activation, osmoregulation, and photosynthesis. It helps in the synthesis of proteins and starches, regulates stomatal opening for water use efficiency, and enhances plant resilience to stress factors like drought and disease. Understanding the significance of potassium is crucial for effective nutrient management in agriculture. Farmers and agronomists focus on potassium levels in the soil to ensure optimal plant health and maximize yield, as it directly influences crop quality and productivity. The other nutrients listed—nitrogen, phosphorus, and calcium—play important roles as well, but they are represented by different symbols and contribute to different aspects of plant growth.
