What is the main purpose of fertilizers in horticulture?

• A. To increase plant size
• B. To provide nutrients for plant growth
• C. To control diseases
• D. To protect against pests

Answer: (B)

The main purpose of fertilizers in horticulture is to provide essential nutrients that are necessary for plant growth and development. Fertilizers contain macronutrients like nitrogen, phosphorus, and potassium, along with secondary nutrients and micronutrients that plants need to thrive. These nutrients are crucial for various physiological functions, including photosynthesis, root development, and fruit production. While increasing plant size can be a result of sufficient nutrient availability, it is not the primary purpose of fertilizers. Similarly, controlling diseases and protecting against pests are functions associated with different types of agricultural practices, such as integrated pest management and disease control strategies, rather than the core function of fertilizers. Therefore, the focus of fertilizers is solely on supplying the nutrients that enable healthy plant growth.
