Agricultural science is a broad multidisciplinary field of biology that encompasses the parts of exact, natural, economic and social sciences that are used in the practice and understanding of agriculture.

• Production techniques (e.g., irrigation management, recommended nitrogen inputs)
• Improving agricultural productivity in terms of quantity and quality (e.g., selection of drought-resistant crops and animals, development of pesticides, yield-sensing technologies, models of crop growth, in-vitro cell culture techniques)
• Minimizing the effects of pests (weeds, insects, pathogens, nematodes) on crop or animal production systems.
