农学 (nóng xué) literally combines 农 (nóng), meaning 'agriculture' or 'farming', and 学 (xué), meaning 'study' or 'science'. Together, it refers to the scientific study of crop production, soil management, plant breeding, and sustainable farming practices — essentially the academic discipline of agronomy. It is used in formal, academic, and professional contexts, such as university departments, research institutes, and agricultural policy discussions.

Unlike broader terms like 农业 (nóngyè, 'agriculture' as an industry), 农学 emphasizes the systematic, evidence-based knowledge underlying farming. Students majoring in this field learn about pest control, irrigation systems, fertilizer use, climate-resilient crops, and food security. It overlaps with botany and environmental science but remains distinct in its applied, production-oriented focus on food and fiber crops.
