Which term covers the science of crops and soil?

• A. Agronomy
• B. Horticulture
• C. Entomology
• D. Aquaculture

Answer: (A)

The main concept here is understanding which field studies growing crops in the field and managing the soil that supports them. Agronomy focuses on crop production and soil science together—how different soils, nutrients, moisture, and climate affect yields, and which management practices (like fertilization, irrigation, crop rotation, and pest control) optimize farming results. Horticulture deals with garden crops and ornamental plants, often on smaller scales or in different settings. Entomology is the study of insects, and aquaculture is farming aquatic organisms. Because agronomy directly integrates both crops and soil to improve agricultural production, it is the best fit.
