Which term describes the application of scientific principles specifically to agriculture?

The term that accurately describes the application of scientific principles specifically to agriculture is agronomy. Agronomy focuses on the science and technology related to the production and use of plants for food, fuel, fiber, and land restoration. It encompasses a range of disciplines, including soil science, genetics, and meteorology, to optimize the growth and yield of crops. Agronomists work on improving agricultural practices to enhance productivity and sustainability, making it a crucial field within agriculture.

While husbandry is related to the care and breeding of livestock, it does not fully encapsulate the scientific principles applied specifically to crop production. Consequently, agronomy stands out as the most fitting term in the context of applying scientific methods to agriculture overall.
