Agronomy is the application of plant and soil science to crop production. Horticulture is the science and art of cultivating fruits, vegetables, flowers, and ornamental plants. Agronomy emphasizes staple food crops, such as corn, rice, beans, and wheat, which are produced on a large scale and represent the foundation of our human food supply. Forage plants and hay crops are also considered agronomic crops and are the feed base for the ruminant livestock industry on pastures and rangeland. Horticultural crops are used to diversify human diets and to enhance our living environment. Vegetables, fruits, flowers, ornamentals, and lawn grasses are examples of horticultural crops and are typically produced on a smaller scale with more intensive management than agronomic crops. Some horticultural crops are grown for aesthetic enjoyment and recreation.
